\section{\label{sec:introduction}Introduction}
This Memorandum of Understanding (MOU) outlines the activities and
responsibilities of the \instname{} (\instabbr ) \groupname{} within
the Jefferson Lab (JLab) \gx{} collaboration.  It describes
the commitments of all three parties to the successful completion
of the \gx{} experiment and is subject to regular review and updating
by all three parties. The manpower commitment and deliverables 
described in this document are contingent on continued funding of 
the \instabbr{} group.


The goal of the \gx{} experiment is a mapping of the spectrum of gluonic
excitations with the ultimate objective being a quantitative understanding of
the nature of confinement in QCD.  To achieve this goal a hermetic detector,
the \gx{} spectrometer, optimized for amplitude analysis, will be constructed
in a new experimental hall (\hd ).  A tagger facility will produce 
$9 GeV$ linearly polarized photons via coherent bremsstrahlung radiation 
of $12 GeV$ electrons through a diamond wafer.  To achieve $12 GeV$ 
photons CEBAF will be upgraded to $12 GeV$ with additional cryomodules, 
modified arcs and an additional arc.  Critical Decision 0 (CD-0) for the 
upgrade and \gx{} was awarded by the Department of Energy (DOE) in April, 
2004.  The \gx{} collaboration was formed in 1998.  The fourth and most 
recent version of the \gx{} Design Report was issued in 2002.  The project 
has been reviewed externally and by the JLab PAC.  The \gx{} management 
has been in place since 2000 with a Spokesman, Deputy-spokesman, \hd{} 
group leader and an elected Collaboration Board.


This MOU does not constitute a contractual obligation on the part of 
any collaborating \gx{} institution or JLab. No contractual obligations 
shall arise except pursuant to appropriate written authorizations by each 
party. All foregoing work is subject to the appropriate written contractual 
agreement of the parties.

\section{Institutional Commitments to \gx{} }
\subsection{Commitments to \gx{} R\&D }
%
By the end of 2005, the \instabbr{} group will complete work on construction,
and testing of a prototype straw tube chamber to be used as the central 
tracking device of the \gx{} detector. Based on both this work and continued
Monte Carlo studies of both the detector and physics, the group will develop
final design for the \gx{} central tracking device.  A rough time line
for the completion of this work is shown if Figure~\ref{fig:rndtimeline}
and detailed in Table~\ref{tab:rndtimeline}.

+6 to +8 months  & High Voltage Testing \\

+10 to +12 months & Structural Tests \\
+11 to +13 Review of the Design \\ 
\end{tabular}
\caption[]{\label{tab:rndimeline}The time line for completion of the
R\&D effort. Start time is April 2004.}
\end{table}

\subsection{Hardware Deliverables for \gx{} }

Upon completion of the final design for the \gx{} central tracking device,
the \instname{} group take on the responsibility of building the central
tracking chamber for the \gx{} experiment. This responsibility includes
the detector itself. The electronics that mount directly on the detector
and cables to take the signals to the Data Acquisition Electronics. 

The tasks necessary to build this chamber are shown along with a time line
in Figure~\ref{fig:consttimeline}. The start date for this construction
project is contingent on funding for the \gx{} experiment. The tasks
outlined represent approximately three years of work by the \instabbr{}
group. This plot is also detailed in Table~\ref{tab:constimeline}. 
With a flexible purchasing procedure, it may be possible to preorder
much of the material, and shorten the project by up to one year.

+24 to +30 months & Installation of electronics. \\
+30 to +36 months & Chamber tests. \\
+36 to +39 months & Delivery to JLab. \\ 
\end{tabular}

\end{table}


The current scope of this work does not include the \emph{High Voltage}
control and monitoring system, nor the final gas mixing and control system.
The most efficient use of resources in this regard would be to have 
a common \emph{High Voltage System} for the entire experiment and common
controls and hardware for all gaseous detectors in the experiment. 

\subsection{Software Deliverables and Support for \gx{} }

The \instabbr{} group has historically provided support for the 
\gx{} Fast Monte Carlo, (HDFast). The group will continue to 
provide this support and assistance to groups wanting to run the
code.

The \instabbr{} group will work to develop and test tools for Partial
Wave Analysis that will be  generally applicable to understanding
and \gx{} data. Of particular interest to the \instabbr{} group is
a systematically correct way of removing or handling baryon resonances
in the \gx{} data. A large portion of this work will be working 
with unpolarized photoproduction data from the JLab CLAS experiment.
These efforts will involve the study of both the Baryon and the Meson
systems with primary goal of developing better tools and techniques
to analyze the two systems together.

\subsection{Support for Running The \gx{} Experiment}
%
% This includes maintaining detector components, serving as experts
% on call for various parts of the detector as well as normal shift
% assignments.
%
\subsection{Support for Analysis of \gx{} Data}
%
% This includes calibration of detectors, data quality checks 
% and data processing and management tasks.
%
\subsection{Theoretical Support to \gx{}}
%
% This section describes theoretical calculations relevant to 
% GlueX as well as lectures to educate GlueX collaboration
% members.
%
\subsection{Collaboration Responsibilities}
% 
% This sections describes management roles played by group members.
% It also includes committee memberships that are purely in support
% of the functioning of the experiment. This might include publication
% or speakers committees.
%
Curtis Meyer currently serves as Deputy Spokesperson of the \gx{}
collaboration. The \instabbr{} group fully supports this effort and
any other efforts deemed necessary by the collaboration.

\section{Funding and Infrastructure}
\subsection{\instname{}}

The \instname{} group will provide funds associated with support of personnel
and travel to carry out the tasks outlined in this MOU.

The \instname{} group will request funding from the Department of Energy 
and from Jefferson Lab to carry out work beyond the scope covered 
by this MOU.

The \instname{} group maintains a fully equipped shop and a full time 
technician, (Gary Wilkin).  These will be available  to carry out the 
fabrication work covered by this MOU. \instname{} will also provide 
many of the smaller components needed for the fabrication as part of
their normal operating budget.

The \instname{} group controls lab space necessary to both build 
hardware and perform tests of the resulting equipment. This space 
exists and is assigned to the \instabbr{} group involved in \gx{}. 
In addition, the \instabbr{} group has or will obtain sufficient 
electronics, test equipment and infrastructure top carry out all needed
tests on both the prototype and the final chamber.

The \instname{} group will provide written time lines for the completion of
various phases of the project and written reports on the outcome of each
of these various phases.

\subsection{The \gx{} Collaboration}

The construction of the final central tracking chamber will be contingent
on securing additional funds from outside sources specifically for this
project. The \gx{} collaboration will develop a global plan for the 
timely funding and construction of all elements of the \gx{} detector. 
The collaboration as a whole will seek funds to build all parts of the
detector in a coordinated fashion.

\subsection{Jefferson Lab}

\begin{itemize}
\item JLab will retain ownership of all deliverables as specified 
under individual contracts and MOUs.
\item JLab is responsible for all engineering aspects of \gx{} and 
all aspects of the detector integration that require legal and certified
engineer approval.
\item JLab assumes all legal liabilities related to \instabbr{} provided
and installed equipment while located on JLab property.
\item JLab will provide reasonable assistance to the \instabbr{} group
to assure smooth flow of information regarding DOE procedures and 
protocols as they affect the funding of the work agreed between JLab
and \instname .
\item JLab will provide physical space to \instabbr{} personnel and for
their equipment to facilitate their work on \gx . The \instabbr{} group
will convey such requirements to JLab with reasonable advance notice
in the spirit of good relations and sound planning.
\item Official contact between the \instabbr{} group and JLab will be 
through the \hd{} project management office and its JLab appointed staff.
\end{itemize}
