The PSL is now up and running after this morning's power glitch. Once the front ends were alive the PSL came up without any issue. I reset the injection locking relock counter.
While it was down I took the opportunity to power cycle the diode chiller. The front panel of the chiller has been scrambled since the chiller started behaving funny (alogs here and here), the power cycling cleared the screen up; the water temperature is still oscillating. We are in talks with the chiller manufacturer about this issue.
