Run Plan for February 5 - 7, 2016: Locking up the hall At 2pm (Friday), check the status of the activities in the hall and notify RC if there are potential delays for the lockup at 3pm. Work with the hall work coordinator (Doug Tilles or his designee) to make sure hall is ready for sweep at around 3pm. Make sure experts, beamline, ECal, SVT, and slow controls, checked their systems befor the lockup. When ready notify MCC to start seep and lockup of the hall. Make sure all necessary monitoring GUIs are up and running. Make sure beam viewer screens are up. Bringing beam to the hall (consult with RC with any problem): First beam comes to tagger dump. Ask MCC to turn on tagger magnet (they have procedures to set the correct current), check that beam type is "Photon" on the BTA GUI (can be opened from "Beam" GUI). Follow instructions under "Procedures" on the documentation tab for "Beamline" to establish beam to the tagger dump. For establishing beam on the tagger dump beam current should be <10 nA. Make sure nA BPMs are calibrated while running beam to the tagger dump (this will depend on time of the day when beam and experts are available for BPM calibration). After reasonable beam is established on the tagger dump ask MCC to degauss the tagger magnet and deliver beam to the Hall-B electron beam dump (to Faraday cup). Here "reasonable" means beam profile is close to the design values at 2C21 and "tagger" (2C24) harps. Not much has been changed in beam optics from the previous run, it is still 1 pass beam and we expect beam profile at 2C21 harp to be < 0.1 mm and < 0.4 mm on 2C24 (tagger) harp, both in X and Y. Make sure that SVT collimator is on the beam when sending the beam through HPS to the electron dump (Faraday cup). Follow the instructions under "Procedures" on the documentation tab for "Beamline" to establish beam to the electron dump. In order to have reliable readings on two important BPMs, 2H00 and 2H02, beam current should be >25 nA. All studies should be done with beam currents between 25 nA and 30 nA. If needed move SVT protection collimator up/down to see beam clearly on the viewer (motion should not be more than a 1mm, the preset positions should be good to few hundred micrometers). Before moving forward with 2H02A harp scans and beam profile tune, stripline BPMs 2H00 and 2H02 must be calibrated and orbit lock must be operational. The required beam profile at 2H02A harp is: X-width <~0.25 mm, Y-width <~ 0.05 mm, and the tilt angle <15 degrees. If beam profile is not exactly as required, but beam position on BPM is stable within 0.2 mm in X and 0.05mm in Y, the following still can be done: Verify positions and sizes of SVT protection collimator holes as assigned on the GUI. Center beam on HPS using ECal rates (see instructions under "Procedures" on the documentation tab for "Beamline"). Mark the beam position on the chromox screen and turn on HPS chicane magnets. Study rates on ECal channels as a function of beam current without and with production target. Check the FSD system (see procedures on the Documentaiton page) If beam stability and profile are acceptable, start centering it on HPS SVT using SVT wires (see instructions under "Procedures" on the documentation tab for "Beamline"). Start trigger rates studies, establish running conditions. Miscellaneous Notes: If you change beam current, turn orbit locks off first, there is a current - position dependence on the stripline BPMs 2H00 and 2H02 Do NOT change chicane magnet currents when beam is on Do not run more than 60 minutes above 30 nA without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents.
