Blue Jeans Connection Information

  1. Enter Meeting ID: 895800575
  2. Press #


  1. SHMS Drift Chamber Update - Deb
  2. Survey of HMS and SHMS spectrometers. Presently doing surveys to set the angle plates for the SHMS. Do we need surveys for the HMS plates?
  3. Commissioning plan updates from detector systems
  4. Status update from detector owners, calibrations, efficiencies, etc.
  5. Review systems owners and update information
  6. Address system specific points of interest for the Fall 2017 run



  • Sam, a UVA undergraduate, will be working with Dave M. for the summer

Beam Line

  • Dave G. reported that the SHMS angle plates were surveyed and aligned, see log entry SHMS angle scale adjusted and SHMS rotated to 7.5 degrees
  • The SHMS was surveyed yesterday relative to the angle plate reading after movement
    • The data has not been analyzed yet
  • A systematic alignment and survey is currently set for the summer


12 GeV Drift Chambers

  • The chambers currently reside in the ESB
  • Readout ribbon cables have been fabricated, bundled, and labelled
  • Nanometric discriminator cards have been installed in DC2
  • Standalone cosmic DAQ is currently being assembled
  • LV system is being configured and will be deployed later this week
  • HV has already been implemented
  • Cosmic test stand setup is in place



  • Recently integrated into the Hall C DAQ, see Brad's E-Log entry
  • Current efforts are focused on modifying the online analyzer to be able to read the data in the Hall C CODA format

Drift Chambers

  • Deb showed some slides regarding the correlation of drift time spectra and cathode voltage
  • The spare chamber, currently in the TEDF high bay clean room, should be ready by next week
