For reasons unknown the laser power supply was found to have been tripped off manually sometime late last evening.  Appears someone actuated the switch as it is a guarded switch and it was found this morning in the 'open'power off ' position.
Upon actuation the laser quickly came up in power and phase locked as expected. all stage operations are not normal.
Users are reminded that the Ebeam lab is a restricted access area and that they are to confront anyone whom comes into this area that is not a qualified user on the tools.
