RC: John Jaros (757) 575-7540 9 575 7540 from Counting Room PDL: Stepan Stepanyan Every Shift: Follow run plan as outlined by RC Once BPMs are calibrated, ask MCC if orbit locks are on, they should be. Keep shift summary up-to-date in HBLOG Update the run table on Google Docs: Google Docs 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 22-23, 2015 (day/swing/owl) Overview: Machine will be down noon until about 4PM for RF separator work and establishing Halls A and D. HPS shifts are on. Program: 1) Take SVT baseline data with DAQ when beams are off; (2) when beams are back, re-establish beams to tagger and Hall B dump;(3) set up chicane and perform SVT wire scans and harp scans to confirm orbit;(4)re-establish DAQ and data taking; (5) scan target vertically and horizontally, halo rates vs target (5) Take data. Subsystem commissioning studies: more trigger commissioning studies, SVT commissioning. While beams off, take SVT baseline data with DAQ When beam is back, work with MCC to restore beam to Tagger Dump After MCC finishes beam tune record harp scans at 2C21 and 2C24 make sure no bleedthru After beam tune is done send HPS scaler GUI to the logbook with proper comment Restore Beam to the Hall-B Faraday cup Dump and Setup HPS. Ask MCC to turn OFF the beam, turn OFF and degauss 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. 4mm SVT Protection collimator in place Restore 1 nA CW beam and make sure beam is at y~-5mm; x~5mm Record spot. Check position at 2H02 harp, check centering in Ecal. When beam looks ok, go to 10 nA Energize chicane. record scaler and bpm settings and beam location on screen. Energize HPS chicane - ask MCC to turn beam OFF, ramp up magnets to desired currents according to procedures . Use currents found last night. After magnets are at required settings (will take ~40 min) ask MCC for 10 nA beam check spot on chromax viewer, and Ecal confirm beam position with SVT wire scans Be very careful when changing magnet currents when beams are on. Must enter new current ACCURATELY. Small steps only. After chicane is set, record halo counter rates, turn beam off and insert HPS target, 4um W Do horizontal scan of beam on target. Using table provided, first change Frascati settings, then PS settings to move beam left and right on the target with ~1mm step. Small changes only. Return to nominal beam positon. Do vertical scan of target at fixed beam position. Measure halo counter/ecal rates vs target position Do scan of SVT collimator, measuring counter rates vs SVT collimator position with nominal beam position. Subsystem Commissioning Studies. Begin Data Taking. Make sure DAQ is OK for data taking More Trigger commissioning data runs. See Commissioning document on run wiki. When SVT is ready for data, begin integrated data taking. Call Omar. Absent other requests, take data at 50 nA.
