The Big Family Readiness Review 1 st Run Period: Threshold Pion Production 2 nd Run Period: Transversity & d2n 3 rd Run Period: A y & 3 He(e,ed)
Why are we having this review? - John Domingo
E04-007: Threshold Pion Production Left Negative (Right Arm Not Required) Cryo-target 20 cm race track plus new 4 cm pancake target BigBite with Wirechamber Hadron Package ( ) –two wire-chambers (one upgraded) –dE/E trigger scintillators –updated frame & cabling 4 He Bag System
E & 11: Transversity Left (S1, S2M, A1, RICH, Gas Cherenkov, Pion Rejector) 30 with Electron Package –three wirechambers (two chambers from Hadron package) –upgraded preshower & shower (scope pending funding) –new gas Cherenkov (critical for d2) –GEN timing scintillators Polarized 3He Target System –transverse field coils –large diameter exit beam pipe Fastbus for Chamber Readout
E06-014: d 2 n Left (S1, S2M, A1, Gas Cherenkov, Pion Rejector) 45 with Electron Package –detectors the same as Transverity Polarized 3 He Target System –change to in-plane polarization
E05-015: A y The Big Hop (Left HRS and BigBite Trade Places) Left - 20 with Negative Polarity Right - 20 with Negative Polarity BigBite with neutron detector for large angle Polarized 3 He Target System –nominal exit beam-line
E05-102: 3 He(e,ed) Left 15 - X with Negative Polarity Right 12.5 with Negative Polarity BigBite with Hadron Package & Hall A Neutron 70 –system check during E Polarized 3 He Target System
Schedule and Milestones Group DAQ Layout Finished DAQ Completed and Tested Begin PreShower / Shower Upgrade –Scope of Upgrade Still Pending Funding –Project Defined By April 1 st Install Chambers In Hadron Package Complete Hadron Package Testing Submit FY08 Requisitions For Transversity & d2 –Local Construction Items –Cherenkov Gas Complete Electron Package Testing –Must Have Chambers Back In Hadron Package Before Christmas Install Threshold Pion Experiment Install Transversity & d 2 n Experiments Complete Neutron Detector Veto Install A y & 3 He(e,ed) Experiments (The Big Hop)
