Final meeting in Santa Fe - week of Mar 25
Alex will make 30-min presentation on Mar 27 - JLab has 2 hrs
Note the new aggressive schedule:
1. Start construction in 2003
2. First Physics in 2007
Need CDR by march, 2002 (12 months from now)
Conceptual Design Report
1. What we need from Lab Management (in April):
Project Office established
Project Director appointed
Hall D Group formed
2. What we need to do
Set up (with Lab Management) a review
Subsystem reviews to identify R&D needed
3. What we need from DoE/NSF
Funding to start projects which need no R&D
Funding for R&D (after we identify)
Beam Line & Civil Issues
1. Roger Carlini will discuss civil - plans, drawings, milestones
2. Beamline issues - magnets (Novosibirsk?)
3. Richard Jones and Jim Kellie and Dan Sober will discuss:
Tagger design
Tagger magnet
Microscope
Diamond Crystals
Magnet Issues
Paul Brindza will discuss the move of the magnet from LANL to JLab. An MOU between LANL and JLab is being prepared. Move into Test Lab by early 2002.
IU Group (Scott, Eric and Craig) visited UIUC to look at magnet mapper for the G0 magnet.

Visit to KLOE (Frascati)
Tests at TRIUMF
Tracking
1. Curtis Meyer and Paul Eugenio will discuss plans:
Borrowed straw tube chamber from BNL
dE/dx studies

3. PM placement and fringe field issues (for TOF/Cerenkov, LGD)
TOSCA issues
Tests using Helmholtz coils
Electronics & DAQ
1. FADC Project (Paul Smith)
“one size fits all” - calorimetry and dE/dx and tracking
Robotics assembly facility at IU (Jlab?)
2. F1 TDC Project (Elton Smith and Dave Doughty)
Needs of the TOF?
3. Other issues
Bus - re-examined
Event building
CODA?
Controls
Physics Issues
1. Effectiveness of photoproduction in producing exotics
Diffraction (plucked string) vs meson exchange
2. Compilation of relevant photoproduction data and phenomenology
3. Certification of the PWA formalism
Beam polarization (what can be done with polarized target?)
Re-examine the isobar approach
Backgrounds
4. Other physics:
Spectroscopy of ssbar
S/P Interference
Radiative decays
Measurement of Vus
Simulations
1. Hall D Grid Approach/Virtual Experiment Environment (Larry Dennis)
Proposal to DOE Office of Advanced Scientific Computing (FSU,IU)
2. Preparation of Simulations for CDR (Larry Dennis, Elliott Wolin)
Crisp organization and cooperation is CRITICAL
Define issues for each subsystem
Understand where to apply GEANT or MCFAST or other
Manpower Needs

Funding Strategies
1. SURA
Funding for theory activities (workshops, school?)
2. DoE/NSF
Need to be aggressive in light of budget cuts in Bush era
Early funding for projects not requiring R&D
JLab or Universities? - model for funding
3. NSERC
4. European sources
5. CDRF - and other sources for support of Russian physicists
