meclas.TTL_shutter.

  • meclas.TTL_shutter_Status()                                  tells you which TTL shutters are currently opened vs closed
  • meclas.TTL_shutter.Toggle('openall')                    opens all TTL shutters
  • meclas.TTL_shutter.Toggle('closeABEF')                closes AB and EF TTL shutters
  • meclas.TTL_shutter.Toggle('openWW')                 opens WEST TTL shutter
  • meclas.TTL_shutter.Toggle('closeXX')                    closes EAST TTL shutter
  • meclas.TTL_shutter.Refresh()                                 see text below
  • If you toggle the shutters using the button or the EPICS screen instead of Python, nothing is keeping track of the shutter state, so you will confuse the laser -- it will think it has one state when really it has another! As such, never touch the button or the GUI unless absolutely necessary!
  • If things get out of whack, you can always come to the hutch, visually verify that ALL SHUTTER ARE OPEN, and then type in the command: TTL_shutter_refresh() This will reset the counter/reference back to being all open.
