|
Yesterday Aaron, Isaac and Anders inspected the EZL connection from the service chase to the optics tray using the goose neck camera in SHC. No issues or shorts could be identified. Containment box was not removed.
Today David and Anders opened up two panels on the service cap and inspected the EZL connection. No issues or shorts could be identified. Photos available on DocuShare.
Next step will likely be to remove the containment box and inspect the optics tray. |

The containment box was removed yesterday. One of the main insulators on the source tray had cracked at the rear close to the bolt to the source tray mounting plate (see photos using link above)
Troubleshooting continued this morning with disconnection of the optics tray from the module. The banana plug copper tube connection was removed form the optics tray side. With the connection removed, the measurement showed open line on top of the module indicating that the problem is on the optics tray |

TM#4 ,with UC#22, was moved from the south hot cell to the east target station. Upon lowering the module down it made contact with the IMC, At that point the module was removed and placed back in the south hot cell. The IMC was inspected and problem corrected and the module was moved back to the east target station without a problem.
|
The IMC (ITA0160) appears to have a dent in it from the contact with the Target Module. The pressure on the IMC was found to be about negative ~3 mmHg and was increased to ~20 mmHg to attempt to retract the IMC further away from the TM. This pressure is similar to the pressure used at the Conditioning Station. The bellows appears not to be symmetrically compressed. It should be inspected again and pressure checked and monitored for upcoming module moves. |

The 2A2M19 beam profile monitor did not work and was e-faulted. After initial troubleshooting 2 blocks were removed form ITW to inspect the entrance module where the beam monitor is installed. The cable was found not to be connected and was quickly fixed. Blocks reinstalled. The work was done by Maico, Travis and Anders |
