General Update Jian-ping Chen, JLab SoLID Collaboration Meeting May 6-7, 2016

Overview Progress Since Last Meeting (Jan.) SoLID Time-line discussion with JLab management February Budget Briefing at DOE, time line presented to DOE Pre-R&D discussion with DOE (Paul) Stony Brook Workshop Focus on physics: transversity/tensor charge; TMDs (OAM, 3-d Imaging) Trento Workshop Broad discussions, issues, new developments Address Recommendations: Science SIDIS: workshops, projections/impacts, systematics, simulations/tracking PVDIS: background simulations, trigger; New initiatives: PVDIS-EMC, PVDIS-Spin; workshops J/y/TCS: Systematics, performance, bin migration, …; workshops GPDs: New initiatives: DDVCS, DVMP on Pol He3, ...; workshops Progress in subsystems Magnet: JLab plan Detectors: ECal, GEMs, TOF, … DAQ/Electronics Software frame/Tracking Simulations: background, trigger

Timeline and pre-R&D plan End 2016: Address recommendations related to science review (August complete the studies of relevant issues, Oct. mail review?) Spring 2017: Update pCDR -> Draft MIE Spring-Summer 2017: Science Review Feb 2018: Budget briefing to have SoLID in 2017/2018: CD0 FY2020: CD3, start full project Pre-R&D/R&D plan: 1st year prepare for science review: simulations, magnet, DAQ 2nd -3rd year prepare for MIE: detectors, simulations Effort continues/increases after CD0 (PED: Project Engineering and Design) pre-R&D plan submitted to DOE, iterations on-going, details requested

Recommendations Related to Science SIDIS Make strong science case: workshops (Stony Brook, ECT, INT) Comparison with CLAS12/SBS Study systematics Tracking Kaon identification (TOF) PVDIS Background study Q2/performance/systematics J/y Bin Migration Background Developing GPD program DDVCS Others (DVMP, TCS with polarized targets)

SoLID-TMD Related Workshops Stony Brook Workshop (http://skipper.physics.sunysb.edu/~abhay/SOLID/SOLID_at_SBU.htm) Physics on Transversity/Tensor Charge help Beyond SM Test (EDM) Physics with TMDs, Orbital Angular Momentum Physics with TMDs, 3-d Imaging Now, What will be before SoLID (CLAS12, Hall A/C, COMPASS,…) SoLID Impact, Future (EIC) ECT Trento Workshop (https://www.jlab.org/indico/event/143/) COMPASS TMD results Polarized D-Y from COMPASS, Fermi Lab, RHIC-W program New study: W+Y, issue Y term not under control at low PT B-Space: Bessel weighting Transversity from SIDIS and dihadron, tension with Soffer’s bound LQCD for TMDs Direct access OAM/GTMD: off-forward SIDIS?

Progress in Sub-Systems (ECal)

Time-Of-Flight Detectors Goal(s): - Initial plan is to have MRPC <100 ps for pion identification up to 2.5 GeV/c - Above 2.5 GeV/c Heavy Gas Cherenkov for pion identification - Kaon identification more demanding requirements: better separation and higher in momentum requires <30 ps resolution with the SoLID SIDIS environment - Tsinghua U: upgrade/improved hardware could make MRPC intrinsic to <20 ps need readout system upgrade Expanding collaboration effort - Joint effort with EIC R&D project, Micky Chiu joined SoLID EIC R&D achieved <20 ps on bench test, lab test now options for readout system - Option with (LA)PPT detector R&D, Junqi Xie joined SoLID See Junqi’s talk for details

New Proposals/LOIs GPD program: PVDIS program - DDVCS on proton: Alexandre Camsonne et al., LOI last PAC with two stages, 1st stage run-group proposal (this time) 2nd stage dedicated run (later) - DVMP with Polarized He3, Zhihong Ye et al., (this time) - DVCS with polarized He3, Zhihong Ye et al., (later?) - TCS withy polarized proton, Dustin Keller et al., (later?) PVDIS program - PVDIS-EMC: Seamus Riordan, et al., resubmission - PVDIS-Spin: Yuxiang Zhao, et al., (this time?) Half day session on Sat afternoon to discuss these new proposals. Will have a formal review session before PAC for the run-group proposals. (other proposals need SoLID collaboration endorsements should also present).
