Found spark signs on TM3's containment on the side of the water blocks. They may be OLD or/and NEW sparking signs, but this in not determined at this moment. Please see picture: first attachment. First and second attachment show the profiles of water block and HV lines.

 We have a ram installed on SHC pole which is 0.5 meter to  module shielding block surface. the readings we got today during TM3 move:
at containment box center (highest reading): 3.14 msv/hr.
at bottom  of shielding blocks: 960 usv/hr.
at 1/4  of  shielding blocks height from  bottom :700usv/hr.
at 1/2 of shielding blocks height from bottom: 340usv/hr.
at 3/4 of shielding blocks height from bottom:140u/sv/hr.
   The Ram is behind the pole and measured the surface which is 90 degree right side of that opened service tray side.

Results of an electrical check on TM#1 with no target attached to it.

 I use this e-log entry for TM1 notes as well  1. TM1 IG1 is a dual filament gauge . Its filament is very close to grid now. It shorted one time during the pumping down. It still works fine so far . But, we may need to change it if we use this module in TS again.

TCS 1G1 and 1G1S are pumped to 5Xe-6 torr. IG2 stayed at 2.5XE-5 torr. Since no target is installed on module , I capped top of HS water line. Maybe, the small o-ring seal in cap is too old, I found a big leak on this seal when i use LD check it. That is the reason IG2 stayed too high. Still, Leak check and helium presuure test are fulfilled on TM1. Leak detector BLR 5XE-7 atm.cc/sec, BP 0.0XE-4 torr9.  Back up pressure is 51 mtorr which is high because of leak on HS line cap seal so LD BLR is high. At this level, Ta+-, Tube +-, MSP,  EE are good.  Other air to vacuum seal are good as well at this leak rate.  I will check and change small o-ring seal in HS cap. The TM1 is functional basically.

Hi Curtis

 

Further to the emergency service call at the Isac Target Hall on Thursday March 23rd, we advise as follows:

 

It was reported that the hoist was making an unusual noise and that there was a strong brake odour during operation.

The lift was completed using the auxiliary hoist.

 

A man-lift was arranged and Senior Service Technician Tom Kauss attended site the next morning to troubleshoot.

He determined that one of two hoist brakes (walkway side) had a strong odour and on closer examination it appeared that the 

brake lining material was breaking down and particulate lining material was getting caught between the lining and the discs.

These lining fragments were rubbing and burning off during the hoist operation.

The end cover of the brake had an accumulation of brake lining fragments 

The lining was not overly worn, but appears to be becoming friable, perhaps with age or exposure to radiation.

 

The brake was cleaned with compressed air to remove the friable material and thoroughly tested. 

A test load of approximately 10 tons was lifted and the hoist handled the load without issue

The brake fragment issue did not recur while we on site and the hoist was recommissioned for use.

 

To guard against the likely recurrence of this condition on this critical application crane, and as both brakes have seen identical conditions in operation, 

we recommend that both brake assemblies be replaced.

The brake assembly would include the brake coil, friction discs, steel brake discs and the brake springs

TRIUMF does not have a spare brake on hand, therefore one of the removed brakes could be rebuilt and kept on hand.

Today, I checked TH crane main hoist  when shielding plug is installed into ITE pit. I did  some jogging actions on main hoist during the operation. Everything looks fine. No burning smell, no strange noise. An outside crane expert suggest that jogging is the worst working situation for crane. We have to use jogging actions during our crane operation. But, we could try to use less jogging when operate the crane.

This morning, The helium pressure leak check on TM4 Ta(-) is done after TM4 finished conditioning yesterday.  LD base LR:8.0XE-9 atm.cc/sec, base pressure: 0.0XE-4 torr. Applied 70 psi helium to TM4 TA(-) water line. The LR slowly climbed to 2.2XE-7 atm.cc/sec, and stopped there. Waited for 5 minutes and change at 2.2 X E-7 atm.cc/sec.
