General Considerations

Jian-ping Chen SoLID-SIDIS Collaboration Meeting

• 12 GeV upgrade: opens up a large window for DIS in the valence region • SoLID: a general purpose large acceptance spectrometer• Uniform and full 2 azimuthal angular acceptance• High Rate Capability: allow for high luminosity • Ideal for precision DIS and SIDIS experiments

• Approved Experiments:• PDVIS (E12-10-007), Paul’s talk• SIDIS I: transversity (E12-10-006), Xin’s talk• SIDIS II: worm-gear (E12-11-007), Jin’s talk

• More proposals to come

SoLID Experiments

• Special considerations for SIDIS:• Identify hadron () as well as electron• Forward and large angle detections• Event-by-event

•Identify major tasks for the SIDIS experiments Ready for the director’s review; Ready for the experiments

•Identify responsible person(s)/group(s) for each task/subsystem

• Magnet (Argonne, Paul Reimer)• Detector supporting structure (Duke, Haiyan Gao)• General (physics and background) simulation (UVa, Zhiwen Zhao)• Neutron background simulation (Syrucuse, Lorenzo Zana)• GEM detectors (UVa, Nilanga Liyanaga, Chinese colalboration)• Tracking (Caltech, Xin Qian)• Electron Identifications

•EM calorimeter: forward angle (UVa, Zhiwen Zhao)• large angle (Los Alamos/MIT, Jin Haung)•Light gas Cherenkov (Duke/Temple, Simona Malace, Zein-Eddine Meziani)

• identifications•Heavy Gas Cherenkov (Duke/Temple, Simona Malace, Zein-Eddine Meziani)•TOF with MRPC (Duke, Haoyan Gao, Tsinghua, Yi Wang)

• DAQ and Trigger (JLab, Alexandre Camsonne, Yi Qiang)• Target (Jlab, Jian-ping Chen)• Beamline/Polarimetry (UVa, Kent)• Infrastructure (JLab, Hall A engineer/design team)
