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 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.
