Entry  Tuesday, October 25, 2011, 08:47, Travis Cave, South Hot-Cell, Standard Operation, TM4, SiC#26 High Powered, Electrical check 

TM#4 with SiC#26 HP has been checked electrically it has passed. It was noted that the Megger check of the Oven to Chassis (earth ground) and Oven to 60kV Common is low but will not hinder running, according to Don Jackson.  Also yesterday the transition piece that sits on the 55 pin connector was damaged from excessive handling, it was removed and repaired and it now back in place.

Entry  Wednesday, November 02, 2011, 13:12, Bevan Moss, Conditioning Station, Standard Operation, TM4, SiC#26 High Powered, High Voltage (HV) testing 

 The silicon carbide targets voltage was raised to 42 kV today before continuous current draw was observed. It took roughly 10 minutes to raise the module to this voltage with only the occasional spark. The ION gauge reading was 2.0 x 10^-6 T, The service cap IMG 3.6 x 10^-6 T, and the secondary vacuum was 4.5 x 10^-6 T. Setup check and conditioning was performed by Pierre.

TM#4 with SiC#26 HP move from the conditioning station to the East Target Station, move went well.

Entry  Friday, October 28, 2011, 09:37, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#26 HP Febiad, SiC#26 installed on TM4 

HP febiad target SiC#26 was installed onto Tm4 on Monday morning.

"JP's" connector required lossing of the two mounting fasteners. Connector was pushed tight to its mating half on the source tray and both fasteners retightened, and the mating checked; it was good.

Two new 7/8 long 3/8-16 fasteners were used for the febiad coil connections.

Installation went well.

Leak check was performed:

 

Base Pressure: 0.0x10-4

Stable leak rate 0.0x10-9

Left vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Right vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Fllod of system with a 6 second spray; no response.

Entry  Tuesday, May 15, 2012, 12:14, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#26, SiC#26 removal TM4 degredation 19x

SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.

Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray. I will again warn that the source trays historically have a life expectancy, and that TM4 continues to show visual signs that the current source tray is rapidly approaching the end of its useful life!

I understand that one of this years goals is to retrofit TM3; however I fear TM4(and possibly TM1) may fail before this can be released. With the current absence of backup source trays and modules I fear we leave the ISAC program in a very vulnerable position.
