\subsection{Organization}
Construction and operation of the DUNE-PT is an integrated effort within the experimental program of the DUNE collaboration.
The DUNE Collaboration management team includes the collaboration Co-Spokespersons, Andre Rubbia (ETH Zurich) and Mark Thomson
(Cambridge University); the Technical Coordinator, Eric James (Fermilab); and the Resource Coordinator, Chang Kee Jung (Stony
Brook University). This team is responsible for coordinating the international effort required to design, construct, install,
commission, and operate the detectors needed to achieve the scientific objectives of the DUNE Collaboration.
The DUNE-PT is an integral part of this effort. This detector will be built from full-scale components and designed to replicate
the configuration of the first 10~kt detector module to be installed at the Sanford Underground Research Facility (SURF) in
South Dakota during the early 2020s. Successful construction and operation of the DUNE-PT will validate the design of this much
larger detector, and the accomplishment of these tasks is among the highest priorities for the DUNE Collaboration over the
timescale of the next few years. Additionally, the subsequent collection and analysis of test beam data from the DUNE-PT will
provide vital calibration data necessary to achieve DUNE's scientific goals.
In addition to taking responsibility for the construction and operation of the DUNE-PT, the DUNE collaboration strongly endorses
the already approved dual-phase liquid argon detector development program at CERN (WA105 experiment), recognizing the potential
advantages of this detector technology, which may ultimately be chosen for one or more of the three additional 10~kt detector
modules to be installed at SURF.
The organization of the DUNE collaboration is shown in Fig.~\ref{fig:DuneOrg}.

\caption{Organization of the DUNE collaboration.}
\label{fig:DuneOrg}
\end{figure}
%
The international DUNE Project Office is overseen by the Technical Coordinator and coordinates the work packages assigned to each
of the different international partners contributing to the effort. The Project Office maintains a schedule covering the entire
scope of the project (incorporating all of the individual work packages) and tracks progress through a detailed set of milestones
embedded within this schedule. The schedule is based on a Work Breakdown Structure (WBS), which within its cascading levels
incorporates all required components of the detector construction projects. The highest-level elements within this WBS
encompass multiple work packages assigned to different international partners. The deliverables associated with individual work
packages become separated at lower levels within the WBS, where the contributions from specific partners are broken out
as independent WBS elements.
The DUNE Collaboration structure incorporates detector and prototyping organizations that mimic the WBS of the project.
All matters related to the design, construction, installation, and commissioning of individual detector elements are discussed
within these organizations. Because these organizations serve as the required interface between the DUNE Collaboration and the
international DUNE Project, they incorporate both a coordinator who reports to the DUNE Executive Committee through the Technical
Board of the collaboration and a manager who reports to the Project Office. The coordinators and managers of the organizations
are also members of the Technical Board, which coordinates activities across organizations and acts on lower-level project change
control requests. Coordination of simulation and data analysis activities are the responsibilities of the Computing \& Software
and Physics Coordinators, respectively, who report directly to the collaboration Executive Committee and manage collaboration
working groups covering the full scope of activities within their areas.
As shown in Fig.~\ref{fig:DuneOrg}, the collaboration structure includes a high-level organization focusing specifically on the
CERN prototyping effort. The interim coordinator of this group is Thomas Kutter (Louisiana State University) and the interim
manager is Greg Pawloski (University of Minnesota). Coordinator responsibilities include defining operational requirements,
communicating with the CERN SPSC and leaders of the CERN neutrino platform, as well as coordination of all activities associated
with the installation, commissioning, and operation of the detector in the CERN test beam area. The design and construction of
the DUNE-PT is undertaken by the DUNE Far Detector Organization, whose interim coordinator and manager is Jim Stewart (Brookhaven
National Laboratory). The DUNE management team oversees all of the collaboration activities related to the design, construction,
installation, commissioning, and operation of the DUNE-PT through the collaboration Technical Board.
The DUNE Software \& Computing and Physics Coordinators will form collaboration working groups focusing on simulation and data
analysis efforts related to the CERN-PT. The current co-leaders of the DUNE effort to develop a comprehensive and prioritized
list of measurements required to evaluate the performance of the detector and provide the particle response models necessary for
DUNE sensitivity studies are Donna Naples (University of Pittsburgh) and Jaroslaw Nowak (University of Lancaster). Complementary
efforts to define requirements on the test beam necessary for making these measurements and communicating with the CERN beamline
coordinator on how to implement these requirements are headed by Cheng-Ju Lin (Lawrence Berkeley National Laboratory).
%The CERN prototype effort is coordinated by the "CERN Prototype Technical Coordinator (CTC)" \cite{LBNEorg}.
%The charge of the CERN prototype Collaboration Technical Coordinator is defined as follows.
%The CERN prototype CTC is responsible for the following:
%
% \item Prioritize and maintain a schedule of collaboration activities regarding simulations and physics analysis.
% \item Prioritize and maintain a schedule of other collaboration service activities on the CERN prototype. These
% activities may include collaboration participation in assembly, commissioning, calibration, debugging, data-taking, shifts, etc.
% \item The responsibility of the CERN prototype CTC shall include maintaining a database of contributions from the collaboration to
% the CERN detector and beam test prototyping.
% \item The CERN prototype CTC shall recruit collaboration personnel and resources.
% \item The CERN prototype CTC shall coordinate with the DUNE far detector L-2 project manager and the DUNE technical coordinator
%\end{enumerate}
%There are currently one CTC,Thomas Kutter (LSU) and a deputy, Greg Pawloski (Minnesota) sharing the responsibilities.\\
%In order to effectively execute the tasks required for the CERN prototype detector and beam test several sub-groups have been created
%and sub-group leaders have been appointed.
%{\bf Measurement Program + Analysis :} Their charge is to develop a comprehensive and prioritized list of measurements required to
% evaluate detector performance and provide detector charged particle response as input into DUNE physics sensitivity studies (beam
%physics, nucleon decay, supernovae, atmospheric neutrinos). And to perform simulation studies to quantitatively compare the relevance
%of various measurements. The leaders are Donna Naples (Pittsburgh) and Jaroslaw Nowak (Lancaster).
%{\bf Beam :} Their charge is to work closely with the measurement group to identify ideal beam requirements, to work closely with the CERN
%beam group to develop realistic beam design to make relevant beam measurements, to evaluate and optimize possible beam injection points and
%beam orientations, to perform beam simulations and provide simulated beam spectra as input for detector response simulations, to identify
%required beam instrumentation for beam characterization, and to develop beam run plans. The beam subgroup leader is Cheng-Ju Lin (LBNL).
%{\bf Calibration :} Their charge is to develop tools to calibrate the performance of the detector, to interface with the physics measurement
%group to prioritize different calibration measurements, and to interface with detector subcomponent working groups to identify all required
%calibration tools and their integration into the detector /cryostat design.
%The calibration sub-group leaders are Qiuguang Liu (LANL) [interim] and Michele Weber (Bern).\\
%The CERN prototype coordinators work closely with the DUNE technical coordinator and the DUNE far detector manager.
%Direct communication with DUNE spokespeople is important for any strategic issues.
%The CTC also coordinates closely with the CERN Neutrino Platform leader.
%The leaders of the "measurement program + analysis" subgroup work closely with the DUNE physics and software tools working group leaders.
%The leader of the "beam" subgroup works closely with the relevant CERN beam-line group leader.
\subsection{Schedule}
The proposed schedule for constructing, installing, and operating the DUNE-PT is driven by the desire of the DUNE collaboration to
complete these activities on a timescale that will inform construction of the the first 10~kt detector module at SURF, which has
a scheduled installation beginning in early 2022. For this reason, the collaboration would ideally like to fully commission the
detector and collect data for analysis prior to 2019. However, the primary collaboration goal of validating the design for the
first 10~kt detector module at SURF can be mostly accomplished through the collection of cosmic ray data. Therefore, although
it would be highly preferable to collect beam data prior to 2019, data collected after this date would still be available in time
to play its essential role in understanding the data to be collected from the first 10~kt detector at SURF.
A schedule that allows for the collection of test beam data prior to 2019 is shown in Fig.~\ref{fig:schedule}. Detector construction
is scheduled to begin in the second quarter of 2016 and the modules would be transported to CERN in two batches so that installation
at the test beam site could begin as soon as the cryogenic infrastructure including the detector cryostat was available. Using
this approach, the detector installation, which is expected to require a little under one year to complete, could be finished by
the beginning of 2018, allowing for an early-2018 filling of the cryostat and a short data run prior to the shutdown. Detector
construction times are informed by recent experience obtained from building prototype detector modules for the 35~t cryostat at
Fermilab, which will start taking cosmic ray data in the fall of 2015.
\begin{figure}[htb]
\centering
\includegraphics[scale=0.34]{figures/150529_CERNproto_schedule.png}
\caption{Rolled up version of a draft schedule for DUNE-PT. A 2 - 3 months data taking period is included in the schedule. }
\label{fig:schedule}
\end{figure}
%The major milestones for the proposed CERN prototype detector construction and beam test is dictated by the DUNE overall schedule which
%foresees to place the first 10~kton detector module underground as early as calendar year 2021. Additional detector modules, possibly of
%different design, are expected to follow at intervals of 1-2 years in a technically driven schedule. Information and experience gained
%from manufacturing, installing and operating the CERN detector test will inform decision regarding future DUNE far detectors.
%The LHC long shutdown, which is presently scheduled for mid-2018 represents a significant constraint on the beam data run schedule.
%Cosmic muon data taking and ideally also beam data taking for the proposed measurement program
%should be acquired prior to the long LHC shutdown in mid-2018. While it is desirable to have results from the charged particle beam run
%available as soon as possible the value of these results is not diminished if they become available only after installation of the DUNE
%far detector.
%Figure \ref{fig:schedule} shows a technically limited schedule which meets the above requirements.
%is based on experiences from the production and installation schedule for the 35~t detector.
%This schedule is based on experience of designing and manufacturing components for the 35t detector which will be commissioned starting
%in August 2015 at Fermilab.
%
%
%Pending an approval of the effort proposed in this document we foresee the following milestones
%\begin{itemize}
%\item early 2017: Cryostat constructed
%\item early 2016: TPC production readiness review
%\item 2016/2017: Engineering Trial Detector Assembly
%\item 2017/2018: Detector Installation
%\item 2018: Detector commissioning
%\end{itemize}
\subsection{Institutional Responsibilities}
The deliverables required to construct and operate the DUNE-PT are summarized in Table~\ref{tab:wbs-detector}. DUNE is a new collaboration
recently organized to incorporate former members of the LBNE and LBNO collaborations and other interested members into a unified
effort to perform the best possible measurements of neutrino oscillations, proton decay, and supernova neutrinos using large-scale,
deep-undergound liquid argon detectors. Institutional responsibilities for specific detector construction activities are still
under development. In Table~\ref{tab:wbs-detector}, DUNE institutions expected to contribute to the production of specific detector elements
needed for the DUNE-PT are listed.
%
\begin{table}[h]

\end{tabular}
\caption{List of work packages and deliverables for detector components and scientific effort.}
\label{tab:wbs-detector}
\end{table}
%
It should be noted that the participation of some institutions on this list is dependent on
the acceptance of recently-submitted or future funding requests from their supporting agencies. A high priority for the DUNE
collaboration management moving forward will be to finalize a matrix of responsibilities among the collaborating institutions. It
is expected that this process will lead to a significant increase in the level of effort associated with the development of all
required detector components. In the meantime, the institutions who have been involved in the proposed design of the DUNE-PT
will be expected to push the effort forward during this transition period to ensure that the collaboration is able to maintain the
proposed schedule for having detectors installed at CERN in early 2018.
Although the construction, installation, and operation of the DUNE-PT will be the responsibility of the DUNE collaboration, we do
ask for support from the CERN neutrino platform in the form of detector infrastructure as summarized in Table~\ref{tab:wbs-infra}.
%
\begin{table}[h]
\centering
\begin{tabular}{|l l c|}
\hline
\textbf{item no. } & \textbf{Deliverable} & \textbf{Contributing Institutes} \\ \hline
3. & Detector Infrastructure \& Beam & \\
3.1 & Cryostat & CERN \\
3.2 & Cryogenics system & CERN \\
3.3 & Infrastructure & CERN \\
3.4 & Beam & CERN \\ \hline
\end{tabular}
\caption{List of work packages and deliverables for infrastructure.}
\label{tab:wbs-infra}
\end{table}
%
In particular, we ask for support for the
construction and installation of the cryostat and supporting cryogenic systems needed to house and operate the experiment as well
as access to common infrastructure within the CERN test beam area such as slow controls and data concatenation systems. We also
request support from the CERN accelerator departments to provide the required beamline.
Construction, installation, and operation of the DUNE-PT will be conducted following all Fermilab and CERN safety regulations.
DUNE management has direct line responsibility for safety and is assisted in this effort by the DUNE project ES\&H manager,
Mike Andrews (Fermilab).
%The deliverables for the CERN single phase prototype detector down to level 3, associated DUNE project
%work break down structure (WBS) numbers and contributing institutions are shown in table~\ref{tab:wbs}.
%
%Work on a MOU between the CERN nu-platform and DUNE describing responsibilities, listing institutions
%involved and defining deliverables has started.
\subsection{Cost estimate and funding sources}
Cost estimates in {\bf core} accounting of the various detector components and infrastructure items that
will be provided for the DUNE-PT by the participating members of the DUNE collaboration are shown in
Table~\ref{tab:cost}. Core M\&S cost estimates do include the cost of the labor hours required to
assemble and install the various detector components. Costing of the
various detector components is informed by the previously mentioned construction activities associated
with building prototype detectors for the 35~t cryostat at Fermilab.
Financial support for the construction and installation of the DUNE-PT will be obtained through the
funding agencies of the various institutions involved in the effort. Current funding available for
the effort is via the DUNE US project supported by the United States Department of Energy (DOE). It
is expected that additional funding sources associated with non-DOE institutions will be obtained for
this effort within the next year. However, even if this does not occur, the funding profile for the
DUNE US project over the next three years is by itself sufficient for supporting DUNE responsibilities
to the DUNE-PT, which the collaboration is supporting as its highest priority activity during this
time period.
%The total estimated cost of the CERN single phase LAr prototype detector is presented in .
%Cost figures are informed by component production for the 35~t detector.
