1. 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)

2. Why are we having this review? - John Domingo

3. E04-007: Threshold Pion Production Left HRS @ 12.5 - 50 Negative (Right Arm Not Required) Cryo-target 20 cm race track plus new 4 cm pancake target BigBite with Wirechamber Hadron Package (40 - 60 ) –two wire-chambers (one upgraded) –dE/E trigger scintillators –updated frame & cabling 4 He Bag System

4. E06-010 & 11: Transversity Left HRS @ 16 - 75 (S1, S2M, A1, RICH, Gas Cherenkov, Pion Rejector) BigBite @ 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

5. E06-014: d 2 n Left HRS @ 30 - 70 (S1, S2M, A1, Gas Cherenkov, Pion Rejector) BigBite @ 45 with Electron Package –detectors the same as Transverity Polarized 3 He Target System –change to in-plane polarization

6. E05-015: A y The Big Hop (Left HRS and BigBite Trade Places) Left HRS @12.5 - 20 with Negative Polarity Right HRS @12.5 - 20 with Negative Polarity BigBite with neutron detector for testing @ large angle Polarized 3 He Target System –nominal exit beam-line

7. E05-102: 3 He(e,ed) Left HRS @ 15 - X with Negative Polarity Right HRS @ 12.5 with Negative Polarity BigBite with Hadron Package & Hall A Neutron Detector @ 70 –system check during E05-015 Polarized 3 He Target System
