Notices in Effect for Shift Crew

  • Please take a screenshot of the spectrometer angles when they are moved to a new position and make a log entry. If working on a kinematic that lasts several days take an image daily.
  • Pay attention to the notices posted in the counting house regarding HMS Q1/Q2.
  • If HMS interlocks when ramping, check the live camera image of the HMS power supplies for smoke/water before clearing the interlock.
  • Hit enter once you type in the angle when rotating(!)


  • Wifi connection in the hall does not work for Steve and Mike's laptop, but works for Mike's ipad. Rounter reset?
