Problem With Separator Pass 4

Log Number: 4048635Logbook(s): Entry Makers: wissmannBody: 

While working on pass 1 and pass 2, we noticed IOT 3's Cathode power supply is faulted. We took an opportunity to restart the power supply but it did not come back to life. This could mean a bad
IOT tube or the power supply is bad. This will need investigation during the next maintenance day. Until then, pass 4 is out of commission.

NOTE!! Pass 4's Cathode PS is tripped which indicates a possible problem with IOT #3 (Pass 4's IOT)

Follow-up Re: Hall A Laser status update

Log Number: 4048625Logbook(s): Body: 

I checked and optimized the A laser output parameters for both 250Mhz and 500MHz, did observation and found no overheating anywhere on the board. Everything looks good except PreAmp readback is still the same (a static number "2") although I tried very hard to tune. For now, we will keep this board in the chassis since the PreAmp readback is only relative and does not affect performance or operation. We have an accurate PreAmp power reading in the PowAmp section for monitoring purpose. I left the freq at 500MHz.
