Every Shift:

Follow run plan as outlined by RC

Keep shift summery up-to-date in HBLOG

Document any beam condition change and send scaler GUIs to HBLOG

Send "scaler_hps" GUI to logbook at least twice per shift or any time run conditions change

Peform 2H02A harp scan ones per shift or when beam conditions changed based on beam monitors (BPMs, halo rates, beam-viewer)

Fill out shift checklist in the logbook, HBLOG, using template at least ones per shift or when run conditions change

Continuously check quality of data

With any issue contact On-Call Experts or RC.

MCC Daily Meetings

Run Plan:March 6 - 7

Setup Beam to Hall-B Tagger Dump and Studies of Beam Properties.

Aid MCC to establish physics quality CW 1 pass beam to the Hall-B tagger dump:
When reasonable beam spot is achieved on the tagger dump screen perform harp scans, 2C21 and tagger (2C24) harps. Note: harp scans must be performed with 10 nA beam current
If beam x/y sizes are ~<250 um, proceed with program below, otherwise ask MCC to retune
Set up halo counter gains, see link below

Ask MCC to deliver oval shape beam at tagger (2C24) harp: x-width ~250 um, y-width << x-width, and tilt angle ~0 (if tuning is going to be too long, more than an hour, use whatever asymmetri beam is available)
Continue with 2C24 (tagger) harp scans to check beam tilt angle motion over time, as well as beam position and width stability - ~4 hours with scans every 1/2 hour
Study beam tails as a function of current. Position x(y) wire left then right (above then bellow) of beam center at ~3\sigma increase beam current up to 200 nA and record halo counter rates. It is expected to see linear increase of rates if increasing the current does not effect beam profile
Repeat above for position 5\sigma away from the beam center
