Other developments

Two White Papers - Download from Hall D website:

JLab Electromagnetic & Hadronic Physics Town Meeting White Paper

JLab White Paper: Science Driving the 12 GeV Upgrade

Visit with Sen Pete Domenici’s staff - Christoph & Alex - Jan 25

NSAC Considerations

Discussions with various NSAC & extended NSAC members

Curtis Meyer - on LRP Committee

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.

Zisis and George will talk about plans for the barrel calorimeter:

Fiber and PM research

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

Forward chambers

Interest from Moscow State (George Bashindzhagyan)

2. TPC Option (Dick Mischke)

Tracking - advantages/disadvantages

Compatibility with trigger and DAQ (event building)

3. START Counter (Andi and/or Werner)

Particle ID

1. TOF (Dick Heinz)

Tests at IHEP (Protvino)

Further studies at IHEP

Further tests at IU

Requirements of F1 TDC

2. Cerenkov Counter (Gary Adams)

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
