    Minutes

Present at JLab:Hovanes, Nerses, Ani, Krister, Stepan

Present at SLAC: Sho, Takashi


        Magnet power supplies (and other beamline devices)

  * Almost all of the Hall B equipment was disconnected and cables were
    removed, including controls for the magnet power supplies. Stepan
    discussed this with Hall B leadership, and it was agreed that the
    magnet controls will be installed by October. Pair Spectrometer
    magnet and its power supply will be moved downstream at a later
    date, by May 2014.
  * One unpleasant complication is that Krister does not have any
    drawing or schematics, so we will have to use the existing code to
    figure out the connections.
  * We decided to start restoration of the controls with the simplest
    case, pair spectrometer.
  * Stepan also wants to measure excitation curves of the Frascati
    magnets sometime soon.
  * Stepan would like to have other beamline components controls checked
    out. Krister will take a look at them. Stepan will send an email
    with a list of the beamline devices
    <https://mailman.jlab.org/pipermail/hps-controls/2013-August/000010.html>
    to the controls mailing list.
  * At least one of the gausmeters on the space frame should move to the
    forward carriage. We do not need to monitor the field in the tagger
    magnet, therefore we can use the gaussmeters to monitor the fields
    in the pair spectrometer magnet and the Frascati magnets.
  * Actually the HPS controls equipment may end up on the pie-tower
    since the forward carriage racks may be filled by CLAS12 equipment.
  * We will need to setup up some IOCs on the forward carriage or the
    pie tower when Sergey is back from Russia.
