Sorted and packed one 55 gallon drum with low contamination and active stuffs which are placed around silo area in the past. They include old poly water cooling lines replaced from ITE, ITW and TCS, contaminated paper  rags , gloves, and plastic bags,air cooling fans for turbo pumps, EE resistor packaged used on module top before, flow meters and cables used in ITW, etc. After packing, The field outside the drum on contact is less than 10 usv/hr.

Just some notes on the install of SiC#30 on TM3 last month...It was installed with all new fasteners and torque values provided by Anders were used...of main interest is probably the main high current fasteners which were torqued to 150 in lbs.

Entry  Tuesday, July 25, 2023, 16:25, Carla Babcock, North Hot-Cell, Standard Operation, , SiC#45, SiC#45 post irradiation inspection 

Looked at SiC#45 in the hot cell. Looked very clean, no deposits on the heat shield or other components. Target also looked very straight. Only issue we saw was sparking marks on the EE side that faces the ground electrode, in several spots. This target had a bout of sparking when ramping up the protons, so I guess that was the location. Will look for matching spark marks on the ground electrode next time TM4 is in the hot cell. Forgot to take picutres...

Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.

Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module in hot cell) febiad coil left twisted a bit when torqued up.

SiC#32 has been removed from TM2. Quick inspection shows some troubling discoloration on the water cooled connection blocks of C and D as well as the left target heater A.

As for the target, both legs are broken and is has the normal "charge up" marks on the 9 pin connector.

SiC#30 has been removed from TM3. A quick exam of TM3 source tray did not  yield any obvious signs of damage.

9 pin connector on the target showed the usual sparking/arcing marks.

Heat shield has been removed from the target. Inside of heat shield has some unusual marks on it and quite a lot of black deposits.

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.

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  Thursday, January 17, 2013, 10:06, chad fisher, South Hot-Cell, Standard Operation, , , SiC Test Target for TM4/CS 16x

I have inserted the test target for TM4 and the CS into the hot cell.

I had some concerns about the condition of the target which I have discussed with Pierre and he has cleared. Pictures are attached.

Entry  Tuesday, May 26, 2015, 14:34, chad fisher, South Hot-Cell, Repair, TM2, , Shutter replacement Shutter.jpg

The shutter in TM2 was successfully replaced today.

New lock washer and nut were installed onto shutter and nut torqued to 120 ft lbs.

Shutter guide alignment tool was used to insure tapped shutter guide holes were concentric with thru holes in shutter side mounting panel, button head screws replaced and torqued to 110 ft-lbs.

The shutter was manually cycled open and closed by David and everything is to operate well.

Entry  Wednesday, May 13, 2015, 13:55, chad fisher, South Hot-Cell, Repair, TM2, , Shutter removal TM2_20150513_131339.jpgTM2_20150513_134232.jpg

TM2 has been successfully de-shuttered.

All went pretty much according to plan except I had to remove one fastener out of the upper wiring harness (the one that has just been installed) to allow for enough clearance to rotated the shutter guide out of the way...I shutter to think what would have happened otherwise...anyways...

Close inspection of the shutter does show that the "thin" area isn't in very good shape; whether this is a result of removal or just the way it was is hard.Due to the ease of removal I would quess that it may have been a preexisting condition. That being said...I think we may want to consider replacing it.
