What	Postdoc	Description
DAQ	Dustin	AutoDB configuration Recover GreenMonster Make list of epics words for DAQ () Sync monitor between crates (Luis) Pedestal noise Pickup tests BMW scripts (Kent) Hall C BCM signal New PITA QASY (high-speed) feedback script Test new helicity board New config file mechanism (Bob?) Test injector crate Implement/test LHRS crate (Bob) High-rate DAQ system tests ET system test at 240 Hz
Analysis chain	Mark	Decode Qweak ROC structure in PAN (Rupesh/Kent) Run analysis on HAPPEx II data (Mark) QWeak ADC -> PAN (Rupesh) Multiplet (Mark to contact Richard) Multiplet mode in PAN (fall,Richard) Multiplet mode in POSTPAN, Regression (fall) Multiplet mode in dithering (spring) Dithering analysis for PREX system 240 Hz speed/efficiency (Rich)
Detector prep	Dustin	Cosmics Checkout, PMT linearity tests, LED system, Mounting hardware and angles PMT DC linearity (Luis) New (Bogdan) Burle PMT Photonics PMT New/Old base Test for He poisoning (strong baseline current and look for double pulsing) Calculate light yield from HAPPEx III detector (KK/Wexler) [DONE] Online LED pulse linearity hardware (Kent) LED mounting (Rupesh) Studies once hardware is available (Rupesh) Attenuation study (Rupesh, Dustin) Locate/Test/Update mounting hardware (Rupesh/Kent) Determine installation spec: angles and position (Dustin) Installation plan, test installation?? Test detector pedestal noise (Rupesh) Lumi Check running for lumi health Identify spare tubes Test pedestals Electronics pulse LED linearity testing system Relays between counting and integrating mode PREX test configuration design/installation (Dustin)
Moller polarimeter	Dustin	Dustin, Luis and Sasha become experts at running the Moller polarimeter New Custom-FADC DAQ Spilt signals between old and new DAQs pre-stage FADC DAQ work implement parallel DAQ in Fall '09, possibly main DAQ for PREX (Brad, Eugene, Bob)
Compton polarimeter	Mark	Electron detector (Alex, Bob) repair edet planes complete tests reinstall Increase IR cavity power (Mark) Understand transfer function Find script that runs 1/4 wave plate scan Shine green laser through cavity High-rate helicity flip tests (Alex, Bob) integrate electron DAQ and FADC (Gregg, Bob?) Photon Detector install positioning scints (Brian Q.) install new tube/base with linearity test (Megan) LED studies of PMT linearity (Megan)
Accelerator dev/liason	Mark and Dustin	Run 8 more cables from HAPPEx DAQ to source table (Mark,Riad) Kent emailed Riad the requirements for cabling and asked for 2 shifts during the week of July 27, and two shifts in the period Aug 5-8. coordinate high-rate flip test (ATLIS) coordinate low-current running (ATLIS) coordinate spin dance for polarization optimization (ATLIS?)
Modulation		Revive BMW scripts Test BMW system Add new magnets to arc Revive Hall B,C and compton signals Design PREX modulation system Modulation "spec" document (Kent)
Installation planning		When is the detector going in? What tools are needed? Give Ed a list of surveys that are required
Commissioning planning
Documentation and administration		ALIST for watercell removal procedure (Dustin) commissioning plan / schedule (Kent) COO, RSAD, TSOP must be produced. Shift workers must be asked to read and sign before shift. (Kent) Target training must be organised and advertised. Contact Dave Meekins and JP. (Dustin) Shift schedule and signup sheet (Mark) Run coordinator signup (Xiaochao) WAC signup (Mark) Online documentation for shift workers Manpower schedule (Mark) Contact list update (Mark)
PREX		Radiation issues for PREX Possible Shielding? Thermalized neutron estimates to be done with RSAD (Pavel) PREX collimators and Sieve Finalize the design Manufacture Septum Manufacturing Testing in testlab (Fall 2009) Build PREX target ladder GEM detectors Needed for high-rate <math>Q^2</math> during PREX (Nilanga, Kent, KK) Needs design of frontend electronics and DAQ (Nilanga, Kent, KK, Bob)
