|
TM3 new source tray was transferred into SHC on this Tuesday. one hook arm of transfer jig is very close to optic tray tube when engaging the jig on
transfer frame. tube side hook arm should go east side a little bit further to avoid the tube. Also the HS tube top lines to transfer frame
beam bottom distance needs to be watched closely when hooking on the frame.Help from HC window is necessary. By watching on this details, Source tray are |

Ramping up bias/EE/EL on ITE - will see if the HV cage in the pit can hold 60kV or not.
At around 50kV the bias read current starts to get jumpy. Doesn't look like its an issue for the voltage, but definitely instability increases. |
