On June 2 2022, while attempting to install target SiC#42 a gasket fell off the water line. I attempted to remove the target to have the gasket reattached, however the multi pin connector guide pin was loose and was preventing the target from being removed. During the attempt to remove the target it was noticed that an electrical cable in the back of the module had become loose and was dangling. The target was then secured to the module, and then the module was moved to the SHC to complete the job/repairs.
June 3 2022, containment box was removed, Einzle Lens cable reattached and tested, and the multi pin guide pin was retightened.
On June 6 2022, the containment box was damaged while lifting the containment box back onto the module.
The left rear corner of the box caught on the module and the corner weld snapped and folded the corner down about 90 degrees.
With help from Chad, we were able to restraighten the corner with a C-clamp, enabling the box to be reattached to the module.
However the 2 bolts that were on the corner that attach to the module were not able to be aligned and were not used.
The target was reattached to the module, and to save time was brought directly to ITW, skipping the conditioning station. |

Tuesday, November 12, 2019
The FEBIAD source worked well over the weekend. The anode current limit was adjusted twice to stop voltage limiting. About 5E-8 A on the FC with TGHT=580A, TBHT=300A, ANODE=200V,150 mA, COIL=50A. Bias was conditioned to 30 kV |
Thursday, October 19, 2017, 14:20: EE configured for conditioning. HV cage locked up
Thursday, October 19, 2017, 16:46: BIAS / EL / EE at 45 / 22.5 / 0 kV
Thursday, October 19, 2017, 17:16: 30 min without sparking. Lowering to 0. Continue conditioning tomorrow.
Friday, October 20, 2017, 08:22: Resuming HV conditioning
Friday, October 20, 2017, 08:44: BIAS / EL / EE at 45 / 22.5 / 0 kV
Friday, October 20, 2017, 09:48: No sparking. Continue conditionoing
Friday, October 20, 2017, 10:40: BIAS / EL / EE at 50 / 22.5 / 0 kV
Friday, October 20, 2017, 11:30: HV spark (at 52.5 kV) tripped TP2 and TP1s resulting in IG1S and power supplies tripping.
Friday, October 20, 2017, 13:50: Gelo is troubleshooting flickering on/off of ANODE, TGHT and TBHT power supplies.
Friday, October 20, 2017, 13:51: BIAS / EL / EE at 50 / 25 / 0 kV
Friday, October 20, 2017, 14:26: BIAS / EL / EE at 55 / 28 / 0 kV
Friday, October 20, 2017, 14:37: TP2 tripped on spark
Friday, October 20, 2017, 14:51: Gelo has determined there is a communication problem with the PLC on the HV platform. Troubleshooting continues.
Friday, October 20, 2017, 19:02: Troubleshooting did not succeed. Not able to control power supplies. Troubleshooting continue on Monday.
Monday, October 23, 2017, 09:00: After starting the TCS again today communication has been reestablished. Started heater conditioning.
Monday, October 23, 2017, 14:03: Heater ramping previously aborted and ramp down started due to ongoing PLC communication issues. TGHT and TBHT power supplies tripped on timeout around 13:45. Gelo will continue the troubleshooting.
Monday, October 23, 2017, 19:55: Switching off source after operating for 5 hours without any communication glitches detected (fiber optic communication cables swapped between HV platform and BIAS/EZL PLCs) |
