Adrian and co installed a new T to be able to add an instrument loop for O2 and pH monitoring on the low conductivity water systtem (photo). See WP I2021-04-09-4

The crane pendant for the auxiliary hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Canco, supervised by Tom Kauss and David Wang. Installation work was performed in one day (I2021-03-26-1).

Items installed include: new pendant (2 motion, 2 speed)

The existing antenna and receiver box located in the Target Hall were used.

The new system was tested by David Wang. Everything is reported to be in working condition.

Pail 237 only has 200u sv/hr field at 0.5 meter. On contact measurement: 0.9 to 1.6 m sv/hr.and less than 80 count contamination outside the pail.   It is moved to mini storage. We will transfer this pail to cyclotron vault and store it there later.

Frank and I removed Tm3 from TCS to SHC. The move is successful.

 David and I re-connect Entrance module at ITE after the monitor been replaced at SHC. 

 The east entrance module is now back at the east target station.

In mid-2020 design analysis was completed on the steel plate & pin assemblies (ITA6550) used to connect the ISAC target hall crane hook block to the module lifting yoke assembly ITA0494.  The released design note is Document-184431.  

In November 2020 fabrication was completed on two full plate & pin assemblies (photos attached below).  As per the relevant ASME standards (identified in the design note), each assembly has been identified with serial numbers (#1 and #2).  Material test reports for the steel plate and round bar material used for fabrication are attached in PDF format.  For both materials the tested tensile yield strength (from the MTR) exceeds the value used in design calculations (from Document-184431):  117ksi vs 100ksi for the plate material;  138si vs 103ksi for the round bar material.

On February 8, 2021 both plate and pin assemblies were load tested by David Wang and Frank Song.  The total load applied to each was 31,400 lbs (as per the ISAC target hall crane load cell) which exceeds the 125% of rated capacity (31,250 lbs) required for the test.  The lifts were conducted successfully and no deformations or other damage to the assemblies were observed.  Photos of the load test are also attached.

Both plate & pin assemblies are now certified for use up to their rated capacity.  As specified on drawing ITA6550 and in Document-184431, a monthly visual inspection must be performed to check for structural deformation, cracks, excessive wear, and loose or missing fasteners.  In addition, an annual inspection must be performed to check for structural deformation, cracks, excessive wear, loose or missing fasteners, and missing or illegible markings or safety labels.  A written record of the annual inspection must be documented and kept readily available.

 The East Entrance Module has been moved from the East Target Station to the South Hot Cell.

 ITE water flow wheels and coils are replaced. Wheels and coils on Oven, Tube, HS, EE, MSP, Febiad coil, containment box window, dump, dump plug, 2A window, and tank return circuits are replaced with new parts.

First thing I entered into the NHC to install to the target kart mounting clip, and remove excess tools and materials from the hotcell

After the TM3 without a target was lowered into the NHC.

Once inside, with the use of the manipulators, I was able to remove the containment box door, place it on the swivel arm, move the arm out of the way, after the door was return to the containment box and reattached.

 The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today.  5psi helium gas was applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to the matching connector inside the cell.  The end of the wand was sealed using tape.  The Agilent G8601 leak detector was used on "sniffing" mode to check for escape of helium gas from all joints and connectors.  With the sniffing line attached the leak detector test port pressure was 3.9E-1 Torr and the baseline leak rate was 1.7E-6 Torr*L/s.  There was no response while testing all of the three lines.  For all three there was a leak detector response after disconnecting the Staubli fitting, which confirmed that the lines were properly charged with helium.

TM3 has been moved from silo to NHC. The move is successful. NHC ram stand and NHC protection railings are checked and installed. Everything works fine.

2021-03-05. TM3 has been moved from NHC to silo. The move is successful.

ITW water flow wheels and coils are replaced. Wheels and coils on Oven, Tube, HS, EE, MSP, Febiad coil, containment box window, dump,dump plug, 2A window, and tank return circuits are replaced with new parts.

TCS leak check: TCS IG1S1.6 XE- 6 torr. LD  0.0XE-9atm.cc/sec.We used a long pole to spray helium to TCS vacuum seals on diagnostic box and vessel body. Lots helium have been sprayed around the check area.  no leak has been found.

 David and I disconnected entrance module in ITE by following the procedure # 190510. And, the yoke was installed and left on for remote handling later. 

Edi and I inspected roughing pump ITM MP1, primary backup pump ITHMP1, and secondary backup pump ITHMP2. We checked oil level and color on all pumps.  Refilled lubricant to ITMMP1. ITHMP1 and MP2 oil level is fine. ITH MP1 oil color is darker than MP2. But, both them are ok still. Shielding block has been restored after the job.

TM3 old source tray, old target hall high active water resin tank, and  old 2A window RH clamp are transferred from TH to cyclotron lower vault basement 10 and 10A location for storage. They are placed beside and in front of old TM1 and TM2 source tray boxes which stored there in 2018. 

ITE TP1S new pump is installed today. Reset pump life time on controller to 0 hr.

The crane pendant for the main hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Matt at Canco, supervised by Tom Kauss, David Wang, and Adam Newsome. Installation work was performed in two phases since the initial installation did not provide adequate range and an antenna issue needed to be resolved (I2021-01-14-1, and I2021-02-16-1).

Items installed include:

• New pendant
• New antennae
• New receiver box, mounted on main crane control panel in the crane control room

The old receiver control box will be kept for some time in case there is a need to revert to the previous system for some reason.

The new system was tested by David Wang - including using the pendant at the far end of the target hall where range was previously an issue. Everything is reported to be in working condition. Remote mode is functioning as expected.
