Quick note: Shutting Down Lasers as Safety Sign is not working |
|
|
Following up after CTN:2452, the laser safety sign is not working. Hence the lab has been shut down now. All lasers are switched off with key turned to off position. I'll fix the laser safettysign before turning the experiment back one. Possible reasons might be an interlock glitch or bulb fuse. |
