Status Update Jianping Chen JLab So LID Collaboration

Status Update Jian-ping Chen, JLab So. LID Collaboration Meeting June 29 -30, 2017

Overview Progress Since Last Meeting (March 2017) • Meeting with Stuart in mid May: very supportive • Submitted Updated p. CDR Completed iterations with Rolf/Thia on the responses to the Director’s Review recommendations (36). Submitted to Stuart/Bob end of May. Following Bob’s suggestion, added summary sentences to each response. Submitted on Tuesday. Bob already talked to the chair of the review committee. Plan to have mail review. Following Rolf’s suggestion, plan to make the p. CDR be ready for DOE in 2 weeks (by the time of DOE S&T review of JLab). JLab will submit a request to DOE for a DOE Science Review after the Director’s Review committee complete their mail review and all issues addressed. Hope to have the Science Review late this year. § Schedule, budget and pre-R&D Try to keep same schedule: DOE budget briefing 2/2018, starts in FY 2020 Uncertainty in DOE budget. Business as usual for now Need more detailed prioritization: prepare for small amount of pre-R&D becoming available Suggestion from JLab: Consider applying for funding from NSF as well Mid-size $ 4 M-15 M MRI < $ 4 M

FY 2018 Impacts Tim Hallman Medium Energy: • Continuous Electron Beam Facility (Scientific User Facility) operates at 10 weeks (28. 7% utilization) • No CEBAF capital equipment, accelerator improvement project, facility accelerator R&D or general purpose plant funding provided to Jlab • Up to 100 FTE reduction-in-force at Jlab • No initiation of the Moller MIE, which received Critical Decision 0 approval in 12/16. • No medium energy experimental program at FNAL • No RHIC Spin Program • No MIT Research and Engineering Center (University Center of Excellence) • Remaining research reduced 24. 5% JLab User Meeting June 19, 2017 3

Overview Progress Since Last Meeting (continue) § Progress in subsystems Magnet: CLEO magnet Coils, cryostats at JLab Magnet Modeling (Jay) Magnet Steel: encountered difficulty Detector Layout: “finalized” Simulations: GEM digitization (Nilanga)/Tracking (Weizhi) MRPC (Sanghwa), first round complete? ECal (Ye), implemented in GEMC, cross checked, study pre-shower DIS-e vs background (Rich, Zhiwen) … ECal: Continue test, optical fiber, … DAQ: Rate limits n. MRPC for Kaon detection (China, funding passed first round) ….

So. LID Physics Program • SIDIS Projections (comparison with CLAS 12/SBS): (with theory group) transversity/tensor charge done (Ye et al. , PLB 767, 91 (2017)) Sivers on-going Kaon identification (n. MRPC-TOF) Conferences: INT, SESAPS-3 D Session • PVDIS Momentum calibration, Baffle optimization • J/y ECT* Proton Mass Workshop • Developing GPD program Review DVMP (this afternoon)

Timeline § Timeline (Preparation for next stages) MIE document preparation (summer? ) (do we need another step from p. CDR? ) Science Review (fall? ) Budget briefing to have So. LID in (Feb 2018) 2017/2018: CD 0 Director’s Review for CD 1 (next year? ) DOE CD processes (next year-FY 2020) … FY 2020: CD 3, start full project
