-The 75kV power supply is linked into the keyed interlock system. The key & switch labelled BIAS/EZL will unlock it.
-The PS is currently not connected to the epics controls and can only be adjusted manually. |

|
Thursday, February 08, 2018, 16:54
Testing the HV bias I found that the einzel lens was behaving strangely. When I tried to put it higher than 1kV, the current would start spiking
from 12uA to > 100uA. The voltage would jump around quite a bit as well (+/- 100V). Everything seems the way it was before, except the EZL power supply |

|
Friday, February 09, 2018, 08:25 Disconnected the AC power chain from the old bias supply but now cannot turn on the new bias supply
in EPICS because the "TSGBIASSAFETY ok" interlock is tripped. No idea what this means - maybe it checks for AC power?
Friday, February 09, 2018, 08:48 Reconnected power to old bias supply, does not fix problem. Talked to Mike, he thinks it is |

|
Ramped up to 60kV with the new power supply, same as what we did last time with the standard test stand bias supply (see entry #627 ). Much more instability
on the bias current readout (see attached screen shot), develops around 54kV. As well, the old supply read out 37uA at 60kV while the new supply reads
out ~85uA. This could just be an EPICS read back issue though. |
