    Announcements, Eugene

  * Staff position decision made, names to HR
  * Patrizia: we have money for period up to Dec. 9


    Engineering, Tim

  * goni is here
      o install by this week, will be under vacuum
      o according to manufacturer: problems when operated in a small
        range, need to move over full range occasionally
      o need to re-lube once per year
  * target still retracted, but ready to put back in
  * comp cal had to be resurveyed, mistake in y, 1.7 mm


    DAQ, Sascha

  * feature: F125 threshold, fixed by Cody, caused mismatch with config file
  * new firmware installed for FDC
  * new discriminator firmware, allow bi-polar thresholds
      o backward compatible, old software will work
