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. SVT Instructions Before sending beam to Faraday cup, verify (and page expert if otherwise): SVT should be open: "Position" at 0.000 mm in scaler GUI SVT HV is off: all red/green indicators RED in SVT bias GUI The first time sending beam to the Faraday cup after the hall is closed, page the SVT expert. Every Run: a b c d MCC Daily Meetings

Run Plan:March 13-14 (morning) Setup Beam to Hall-B Tagger Dump and Studies of Beam Properties. When Rafayel is on shift, after 4pm, perform beam vertical motion during beam trips and recovery - turn off the beam move tagger harp (2C24) motor to ~97 in absolute position using the expert GUI ask MCC to deliver 100 nA beam, make sure rates on Struck from upstream halo counters are on order of few MHz (if needed make slight movements with motor to get desire rates). Rates can be seen not only on Struck scaler but also on Jorger scaler using fwd_scaler.ald) tell MCC that you will study beam motion during trip and recovery, so they should not bring beam back after the trip without your call start "waveform" program, and ask MCC to deliver beam, 100 nA. When beam trips stop the run after couple of minutes call MCC to see if they are ready to send the beam again, if so start the program again and ask for beam repeat this for at least 10 trips and recovery document each run in the logbook, start and end time and any details if necessary. Send HPS scaler GUI to logbook for every run Setup Beam to Hall-B Faraday cup Dump and Studies of Beam Properties. Ask MCC to turn OFF the beam, turn OFF and degous tagger magnet After tagger magnet is degaussed, change beam configuration on "bta" GUI to "Electron" Insert Chromax screen on the downstream viewer on the beam Ask for ~10 nA beam, watch cctv6 to make sure spot on the downstream viewer is clear and approximatly at the center of the screen Check to make sure Faraday cup and nA BPMs read similar curents Use 2H02A harp do study beam profile and stability (beam current should not exceed 20 nA) Beam Energy ~2.0 GeV Current < 200.0 nA CW Position X Y ~0 mm ~0 mm Profile X Y < 0.1 mm < 0.1 mm Target #1 0 mm Magnets PS Current 0 A Chicane Dipole #1 0 A Chicane Dipole #2 0 A DAQ Configuration ___________________ Configuration file Prescales Thresholds Events Per Run Dead Time
