PMC replacement work delayed due to laser control issues

EdM, JasonO, JeffK, PeterK, RickS

The water cooling for the output shutter for the 70-W amplifier was plumbed in this morning.

We were then unable to start the laser.  The problem was traced to a blown fuse in the control box.

After lots of fault hunting, we finally got the system to the point that the laser would start at about 5:30.

Things seem to be in order now.

We plan to proceed with the PMC swap first thing tomorrow morning.
