Calibration datasets:

1. TPC+HFT: Cosmic rays for TPC alignment (require TPC; opportunistically include HFT subsystems)
   1. FullField (currently 17.6M recorded) [status: done]
   2. ReversedFullField (currently 3.4M recorded) [status: ongoing]
   3. HalfField  (currently 12.8M recorded) [status: done]
      • HalfField is usable data, but FullField provides much better momentum/pointing resolution
2. HFT: Cosmic rays with magnet at ZeroField for internal HFT alignment with commissioning as far along as possible before beams appear (require PXL, IST; opportunitistically include TPC, SSD) for 6+ hours (revised down from initial 48 hours) [status: done]
   • There is interest in an additional week of cosmics at ZeroField using the HFT subsystems alone after the physics running ends this summer to help finalize HFT alignment. As no other subsystems are needed, this can proceed without much organization as long as the HFT group provides people to take shift for acquiring the data, and perhaps allow some other shutdown activities to interrupt them now and then [status: unknown]
3. TPC+HFT: Physics runs at low luminosity (<10kHz) for TPC+HFT global alignment (TPC & all 3 HFT subsystems required)
   1. AuAu15: expecting standard physics data to suffice as calibration data, no special runs necessary [status: done]
   2. AuAu200: still in discussion, but current proposal: beams steered apart once a week, with and without magnetic field (field can be dropped mid-fill), 0.5-1.0M events within full HFT acceptance each time for a total of over 10M each (with and without mangetic field) by the end [status: unknown]
4. TPC: Laser runs with 20k events, newly modified laser_localclock trigger setup that includes "adc" data in all events for TPC alignment
   1. FullField [status: done]
   2. ReversedFullField [status: done]
   3. ZeroField, after ramping down from FullField (hysteresis check) [status: done]
   4. ZeroField, after ramping down from ReversedFullField (hysteresis check) [status: done]
5. TPC: Lasers interspersed in physics and/or cosmic runs every few hours for TPC drift velocity [status: ongoing]
6. EMC²: emc-check runs with 50k events at the start of each collider fill, emc-check trigger setup, BEMC, EEMC, opportunistically include BSMD, ESMD [status: ongoing]
7. SSD: pulser runs for gain calibrations and scanning of all A128C (require SSD, nothing else; 128 runs of 1k events to scan each channel; estimated time is less than 1 minute per run, ~1 hour for full task) [status: unknown]

Proposed strategy as of 2014-02-06 (Thursday), midday:

Towards these goals, the proposed path forward at the moment (for STAR Operations to have final say on how this gets carried out), given the expectation of beam(s) appearing in the collider this weekend:

1. Thursday (ZeroField): Request D3: 20k of TPC lasers with laser_localclock trigger setup at ZeroField [status: done]
2. Thursday (ZeroField): Request B: 6 hours of cosmic rays at ZeroField, including PXL, IST, and opportunistically TPC, SSD [status: done]
3. Thursday night (FullField): Request D1: 20k of TPC lasers with laser_localclock trigger setup at FullField [status: done]
4. Thursday night through Friday and Saturday (FullField): Request A1: cosmic rays at FullField, including TPC, and opportunistically HFT subsystems [status: done]
5. possibly Friday or Saturday (ZeroField): if either (a) the magnet is brought down for other needs, or (b) the HFT group can determine within ~1 day from the initial 6 hours of ZeroField cosmic running that more is needed, continue Request B: cosmic rays at ZeroField, including PXL, IST, and opportunistically TPC, SSD [status: done]
6. during beam development for AuAu15, Sunday+ (ZeroField): when the collider expects notable downtime, sufficient to bring up the TPC and HFT and bring them back down before beam activities restart, continue Request B: cosmic rays at ZeroField, including PXL, IST, and opportunistically TPC, SSD [status: done]
7. after beam development, in a couple weeks (ReversedFullField): Request D2: 20k of TPC laser with laser_localclock trigger setup at ReversedFullField [status: done]
8. after beam development, in a couple weeks (ReversedFullField): Request D4: 20k of TPC laser with laser_localclock trigger setup at ZeroField [status: done]
9. during physics operations, in a few weeks, for the remainder of the operations (ReversedFullField): Request A2: cosmic rays at ReversedFullField, including TPC, and opportunistically HFT subsystems [status: ongoing]
10. during any operations: Requests E & F: as usual [status: ongoing]

Feedback or changes to the above should be sent as soon as possible to me.
