✓ ✓ ✓ Very Near Future: ✓ 5. Submit HIERD (Hazard Identification and Emergency Response Document) – under development (Physics, ESH&Q, Facilities – ✓ SAF110 Safety Walk-Thru!!) 6. Submit experimental procedures.. ✓ ✓ (Hall A Operations Manual and OSPs for “ new ” equipment) December 9! 4
Conclusions • On track for a successful ARR Phase 2 review at the end of January • No show stoppers! Slide directly from Experimental Readiness Review Close-out – things to do, but overall good news! More to come, though… Accelerator Readiness Review (DOE, external) in January
Hall A Base Equipment Checkout Conditions for Spring Run • Run anticipated late March 2014 for 1-4 weeks - 12 GeV milestone 3 pass > 2 GeV pulsed beam delivery (see Jay’s talk!) - planning for some checkout run time at higher (CW) current - beam ~40% at 6.6 GeV, ~60% around 5.4 GeV to avoid trips - accelerator performance and operations budget dependent • Beam dump upgrade planned for Summer 2014 limits activation - agreed on 5 µ Amp limit (other than maybe one short test for cryotarget) and thin targets, 1%, 2% Carbon, 15 cm hydrogen 6

Current Activities in Hall (preparations for DVCS/G M p ) • Beamline – Compton Polarimeter: under vacuum, still need to install detector, work on optics: will try to thread beam through, maybe get some test data – Moller Polarimeter: room temp ready to go, test in Spring run, superconducting upgrade in works – BCMs, BPMs, Unser, preparations for Spring (see Sasha’s talk) – Raster: additional coil in, new electronics to be installed – Arc Energy: need to install new NMR in 9 th dipole, measurement planned planned for Spring run • Cryotarget NOT a – + Swing Arm for Spectrometer Optics comprehensive list – Scattering Chamber + Extension LOTS of room for • Detectors help!! – HRS repairs and upgrades » Shower, Cerenkov, additional tracking plane DVCS collaboration » DAQ and cosmic testing meeting at ODU – DVCS Calorimeter Shielding + Stand, cable mobility Thursday, Friday • HRS Cooldown to start January 2, 2014!
….and beyond… • 3 H target design and venting in preparation for 2015/2016 experiments • BigBite • Assembly in test lab started • New/modified Cerenkov(s) also NOT a • PREX comprehensive list - Pb targets purchased - Shielding design - Polarimetry • New septum magnet designed for APEX - Internal E&D review, to be purchased by collaboration • Polarized 3 He target improvements and continued development - Convection, new lasers, metal windows, double cell… • MOLLER Experiment internal experiment design and costing update in preparation for possible DOE science review early 2014 - All but beamline complete • SoLID Experiment just submitted draft CDR to Physics Division as first step for early 2014 Director’s Review - Working with Cornell to move solenoid in 2016 - Hall A E&D coordinating to make a planning trip
SBS • Project started October 2013 • First Annual Review November 4,5, 2013 – Some recommendations, but overall positive and on track • Spectrometer work at Jlab – Power Supply ordered – 48D48 magnet shipped from BNL – Working on support, stand and motion • GEM order placed to UVA – Pre-R&D complete • Coordinate detector – new! • HCAL Hadron calorimeter – Scintillator ordered from FNAL • DAQ/tracking/electronics…. – Test lab
Summary • Hall A will have first beam time starting in 3-4 months ! – Successful experimental readiness review • Many experiments, many parallel efforts • There is a lot of activity and a lot of work to do - the collaboration is encouraged to take on projects, send students, send postdocs,…. • Exciting times – 12 GeV beam is on the way!
