Homed laser steppers

3 days 11 hours ago
Log Number: 4462784Logbook(s): Entry Makers: brukerBody: 

Homed x/y stage as well as all four attenuator steppers. All of them had lost their reference position due to the power outage, causing the TMG tool to get stuck trying to move the motors past the limit switches.

However, homing the attenuators seems to have incorrectly reproduced the previous reference position at least in the case of D, which now has its minimum power at position 310. The others look reasonable: A 75, B 110, C 85. I tried homing D again and got the same result. This will need to be looked at but doesn't preclude the use of the TMG tool with the present configuration.

cebaf laser HCO work

4 days 2 hours ago
Log Number: 4462761Logbook(s): Entry Makers: shukuiBody: 

I planned to do a laser HCO this afternoon once the power outage was over. However the laser RF was not available due to an issue with the 1427 MHz amplifier. I turned lasers back on after was told the RF was ready but the RF frequency was not recovered from previous setting at 250MHz, so did a manual reset. Then did a partial HCO by checking the laser power and waveforms at different laser modes.
