Phase camera removed from ISCT1

Cao, Dan

We removed the phase camera this morning from ISCT1.

On ISCT1 we left the beam being dumped via a 90:10 BS into the black glass beam dump and then dumped the transmission with razor blades at angles. Double checked the beam dumping whilst DRMI just now. The only thing that is left is the safety curtains and the fibers for the network and PSL light. The sample port on the ALS distribution box was capped so no light will come out of the PSL fiber.
