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. |

Monday, June 17, 2024, 07:36, David Wang, ITE, Repair, , , IG1S elbow oring seal and a blabk off cap oring seal beside the elbow were replaced on ITE entrance module top..
|
IG1S elbow o ring seal and a blank off cap o-ring seal beside the elbow were replaced on ITE entrance module top last Friday. IG1s has a higher than
normal reading so i leak checked entrance module top last Thursday and found leaks to 5x E-8 atm.cc/sec leak on one of (or both of )these two o-rings seals.
they are too close to identify exactly on which one was leaking so both o rings were replaced. other air to vacuum seal on entrance module are leak |

Monday, June 17, 2024, 17:24, Carla Babcock, ITE, Development, TM3, UCx#44, Status of gas system prototype in ITE
|
A new gas system for FEBIAD operation was installed in ITE to enable us to use a calibrated leak which is attached to the target heat shield. This will
allow us to control the quantity and purity of the gas going into the system, and to switch quickly between gasese and pressures.
The schematic of the system is attached. The use of the ballast container is likely not needed - it was originally included in case we want to |

Thursday, July 04, 2024, 01:20, Carla Babcock, ITE, Development, TM3, SiC#46, TM3 conditioning with protons
|
Initial Summary:
TM3 sparking behaviour in ITE has been very disruptive both with and without protons. Protons are at 60uA, target heater at 540A. Max voltage achieved
so far is 51kV, limited by time and a current limit on the BIAS supply. |

Tuesday, July 09, 2024, 16:14, Carla Babcock, ITE, Repair, , , Attempts to reduce ITE:EL trips from HV sparks 8x
|
ITE:EL has been tripping off due to HV sparks. Usually this also trips ITE:Q1/2. These are sitting in side-by-side racks.
The working theory is that HV sparks are returning to ground through the EL and quads, tripping them off. Possibly this is the result of a changed
low impedance ground path. How this change happened could be either something we did during shutdown or the changes we made in TM3, no clear evidence yet. |
