Input power to HAM1 at 1W

Jennie W, Jason O

 

Jason and I added four beam dumps - two before we turned the power up, two after.

There were no beams leaving the table at 100mW but we dumped two beams going towards the PSL septum plate (one was transmission through JM1).

Jason saw one leaving the table after we were at one watt so this and the transmission throuhg JM3 + JM2 are now dumped.

PSL power into HAM1 has been returned to ~100mW and the PSL rotation stage is de-energized and locked out once again.
