Collaboration Meeting Alex Dzierba Indiana U March 16-17, 2001 at JLab 1.Progress since our last meeting 2.NSAC Issues 3.Preparing the Conceptual Design Report A Review of our Design Subsystem Needs 4.Physics Issues 5.Simulations 6.Milestones 7.Manpower Needs 8.Funding Strategies

Since the last collaboration meeting in August, 2000 Produced version 3 of the Design Report Held Information Tech Workshop - CMU (Sept, 2000) G. Fox from FSU - NSF/DOE submissions Management plan adopted and Collaboration Board elected thanks to George Lolos Dec, 2000 APS/DNP Town Meeting at JLab - White Paper puts upgrade/Hall D highest priority Preliminary working groups (TRC) formed Resumed weekly conference calls (discuss schedule) Progress on sub-systems and civil

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 NSERC Support of the Hall D Project

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 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 IU Group (Scott, Eric and Craig) visited UIUC to look at magnet mapper for the G0 magnet.

Magnet Fringe Field Work done by Paul Brindza & Eric Scott Field inside the magnet as a function of z GapsNo -gaps Impacts on the TOF, Cerenkov and the LGD B field (gauss)

Calorimetery E852 LGD now at JLab More from Scott Teige on IU plans to build bases and PM acquisition from IHEP 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) Geometry Radiator 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 V us

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 1.At Jlab Project Office Hall D Group and during construction Physicists Engineers Designers Technicians 2.At Universities Technical staff Postdocs Students

Funding Needs and Timetable

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
