Wednesday, August 19, 2015, 12:04: Water off for purging and leak test.

Wednesday, August 19, 2015, 12:52: Vacuum response observed while David was working on purging the water lines. This turned out to be when the valve to the leak detector was opened.

Yesterday TM2 was inspected in the SHC. Spark marks were found both on the steerer wires and on the ANODE wire. The steerer wires (GND)  were touching the gas lines (60kV). This is likely the cause of the sparking observed at the Conditioning Station (e-log).

 will be performed Tuesday October 6th

Tuesday, October 06, 2015: Maintenance re-schedlued for Wednesday October 7th

 An electrical check was completed by Travis C and Anders M. Note ~250 kOhm between Target and 60 kV common. Leak check was done by Dan M and Chad F on HS and Window circuits. No leaks found

The failed extraction electrode was inspected in the hot cell this morning by Anders and Chad. The following electrical measurements were taken

• EE on target assembly as recieved from TM after online operation. 14 Ohm
• EE removed from target assembly and placed on conductive flat surface. ~1 G-Ohm at 1kV
• EE installed back onto target assembly (fasteners not tightened).~ 0.8 G-Ohm at 1 kV

There was some material deposited on the EE. Some of which has fallen off - possibly during removal of the electrode from the target assembly. It seems the cause of the short was material build up between plasma electrode and extraction electrode. See photos.

The heat shield lid was removed after lunch. This revealed a broken target. The target may have broken after operation (in hot cell).

Friday, November 06, 2015, 14:35: Roughing

Turbos was started around 4pm. Later it was found that the manual valve for the two turbo pumps on the service cap was closed. The valve was open and pumping resumed. The roughing vacuum was high and increased into Saturday morning. The vacuum system was switched off on Saturday.

Purged MP1 using the purging function. Performance recovered. Started rouging.

 One of the wires for the steerers had come loose and was reattached by Maico. Photo on DocuShare

Service cap leak checked this afternoon. Found multiple leaks of 10E-8 to 10E-7 range. Connected to the backing line with IG1 at ~4E-6 T, CG1A around 40 mT. Got responses around large round flange on top, rectangular side panels, water f/t on GND and water f/t on HV. Will resume leak checking tomorrow to attempt to pinpoint sources of leak more accurately.
