Internal Target Experiment at
DORIS
Young-Kee Kim, on behalf of PRC
PRC64 Meeting: Findings / Recommendations
DESY Extended Scientific Council Meeting, November 19-20
•
Proposal of a new experiment at DORIS using the
available MIT-BLAST detector and an unpolarized
hydrogen gas target.
•
The goal is to determine the contribution of multiple
photon exchange processes and to resolve the
existing discrepancy in lepton-nucleon scattering
data. Dedicated data taking for one month per year
for several years would be sufficient.
•
External referees to review. They strongly support
the physics case. The PRC recommends DESY
management discuss with the accelerator group.

Update at PRC
• No `showstoppers’ in running DORIS accelerator for OLYMPUS
• OLYMPUS installation and commissioning in parallel with
DORIS light source operation
• Physics case viewed favorably by DOE
• Meeting of interested physicists March 31st at DESY
• More than 30 physicists from 10 institutions in Germany, Italy,
Russia, U.K., U.S.
• Representation from leading German hadron physics university
groups: Bonn, Erlangen, Mainz
• Working to prepare a detailed proposal with a formal
collaboration by the end of summer 2008
• Window of ~ 3 years (~2009-2012) opening up for many groups
• Formal encouragement by DESY requested
• Next collaboration meeting planned for ~ June at DESY

After PRC meeting…
• Naohito Saito appointed referee to PRC
• I had a meeting with Rolf Heuer, Naohito Saito, and
Joachim Mnich after the PRC meeting
• RH encouraged discussion of an aggressive
schedule where BLAST would be shipped in
calendar year 2009. Also in the proposal we
should discuss a more aggressive schedule to
carry out the experiment. Different schedules
should be considered.
• Need to clarify collaboration size and funding
sources, financial request of DESY
• RM asked to give talk to DESY Extended Scientific
Council on May 26th
• Proposal to be ready by the end of summer 2008

Building OLYMPUS collaboration
and funding for experiment
• I have been in contact with Klaus Rith,
chairman of the German hadronic funding
committee. They will meet in early June
and Klaus has requested a list of items
which would be requested by the German
hadron physics groups
• Dietrich von Harrach has sent me a
starting draft list of items which would be
funded by the German groups

Building OLYMPUS collaboration
and funding for experiment (contd.)
• I have also been in discussion with Italian
groups: Ferrara, Frascati, Rome. They are
strongly interested but constrained in terms of
capital equipment costs by existing
commitments to HERMES and JLab
• I have sent the DESY letter to John Arrington
and Roy Holt at ANL and encouraged them to
become actively involved.
• The St. Petersburg group (Stan Belostotski) are
very interested to participate.

Action Items
• Need to determine cost and schedule to
disassemble, ship, reassemble BLAST toroid and
detectors. Presumably this will be the basis of a
request to DOE later this year.
• Note that it will be very advantageous to have
European groups to come visit Bates before
disassembly.
• Need to identify groups to share responsibility for
various aspects of the experiment
• Need to form active group on OLYMPUS simulations
• Need to determine the date of the next OLYMPUS
meeting at DESY. Goal will be to form collaboration
with clearly identified responsibilities.
