The original HS 45253-23 Had to be replaced due to a leak being discovered during a leak check. Reassembled in 45235-10

However post-TS https://elog.triumf.ca/TIS/Test-Stand/1014 & https://elog.triumf.ca/TIS/Test-Stand/1015, it was discovered there was electrical shorts, components stuck together, including the retainer to the ovens tube. This had to be repaired & rebuilt.

Repairs included opening ITD0542 inner diameter to 11/16"

increasing the slot gap on the HS for the target leg to bottom insulator clearance

Source Cup inner ID opened 0.030" as the short was found to be the tube touching the Cu wall.

Top & bottom insulators were also replaced pre-TS. Checked post TS. They held 540 OL & 1049 OL respectively afterwards.

Run in TS: https://elog.triumf.ca/TIS/Test-Stand/1018

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.

This afternoon, Darwin prepared in the hot lab fume hood the two UO2 slurries to be cut into P2N target discs. Later, I took over cutting both slurries. A total of 49 annular discs were cut and loaded into the P2N graphite container.

The discs thickness was measured by stacking 5 discs on each other, and measuring their thickness in two points.

#discs = 49

Average disc thickness = 0.453mm

Empty cartridge weight = 9.42 g

Full cartridge weight = 39.86 g

UO2+C weight = 30.44 g

The unused material plus the cutting scrap were left in a zip lock bag on a shelf in the right hand side of the fume hood. The center scraps and the loaded target were placed in a plastic tray on the top shelf. The used tools and scales were left on the right of the working area, the napkins on the bottom were put into the garbage bag (inside the fume hood) and replaced, while the only napkin left is the one with the target information (recorded in attached picture).

Attached please find the UCx#13 target description.   

Note:  Target container was coated/sintered with TaC twice.  Would like to see if this will improve the life-span of the target.

Total packed length = 13.2 cm (measured after the sintering process) 

Note:  The theoretical length (ZrC + graphite foils) is 10.52cm    After the sintering process, the stack of discs expanded in length.  To avoid crushing the materials while inserting the endcaps, the discs are gentally packed to 13.2cm.

This target did not pass the test-stand and will not be used for online (unless if it gets approved).  The target container is deformed.  An increase of voltage was observed during the test; perhaps it's a sign of the container being cracked?!  See Test-stand e-log#450 for more details.  

Another target is already prepared and being tested.  (Target Oven WO# 41177-2).

This target was broken right before the end of the final run.  The target was inspected today inside the Hotcell and the pictures can be found here: http://documents.triumf.ca/docushare/dsweb/View/Collection-9357

Looks like the protective layer (TaC coating) was worn out over the course of the run time. 

We need to improve the target coating so this can be prevented in the future.

More info about this later...

 On tuesday July we lower the cathode heater to swap the anode-cathode bias. While lowering the cathode heater a short on the anode developed. 

The polarity swap was not possible because the target/tube assembly has also a short to common. 

We return the configuration has it was and we added two 100 Ohms: 5 W resistor between the common and the heaters to prevent current to flow back to the common. 

The anode short disappear during the cathode and target heating.

Waste accountable for UO2 = 12.57g

The carbonization process started from May 26 to June 4 (9 days).  

See attachment #1 and #2 for the striptools during the UO2/C carbonization

Total Mass UC2 flakes = 35.310g 

 Fri Jun 17 11:56:15 2011

Attempted to make the second batch of UO2/C mixture of carbonization on June 13, but it failed.  The milling jar gasket seal partially came out during the high speed milling.  As a result, the UO2/C mixture squirted out and contaminated the planetary mill (See attachment #3 & #4).  RPG and all other groups were informed.  The planetary mill and the lab were properly cleaned up (see attachment #5), no activities were found after the cleaning.  Attachments #6, #7, #8 are some of the discussion about the UO2 spill.  

All the UO2 taken out from the container (50.23g) is accountable for waste.  

 June 28, 2011 - Re-making 2nd batch of UO2/C mixture was successful.  

Stock#2011_B:

UO2 used = 50.29g

C(grv) used = 10.0g 

Mass of Organics = 4.84g 

Mass of Dried green = 71.96g (the cast was let dry over night <24hrs due to time restriction.  It might not be completely dried as a result of such heavy mass remained.  However, the UO2 waste was very minimum, <5.0g) 

Total Mass UC2 flakes = 56.853g

 Fri Jun 3 12:40:30 2011

Ta#37-LP-SIS (w.o#38634-5)

Filled with 400 Ta foils (25/pk), 4.0 cm in length.  Total mass + Ta wire = 42.32g.  The heat shield was assembled and tested, and the standard salts were added.  Target was installed in the test stand on Jun 1, 2011.  

Fri Jun 17 09:19:46 2011: The following salts have been added: Li, Na, Rb @ 10uL, K @ 5uL, Cs @ 15uL, and Be @ 10uL.

Wednesday, July 06, 2011, 14:08:  TM1 is still under repairing.  It was tested at the test-stand. Target is on the shelve and ready to be used.

Tuesday, July 26, 2011, 15:58:  Salt added before going into the hotcell: Li,Na,Rb,K,Cs.  Target is ready to be used for TM1 test.

Wednesday, July 27, 2011, 10:48:  It was found that the extraction electrode had some arc marking on it (see attachment: EE).  Investigating... 

Wednesday, July 27, 2011, 12:51: After further investigation on the extraction electrode,  we found some black and blue(or green) deposit on the outside surface and inside of the EE.  This deposit is most likely copper oxide, which formed during the HV test.  The EE was removed, and wiped clean with methanol.  (see attachment: EE_CuO).  This target will be used in TM1. 

Friday, August 26, 2011, 09:48:  As per Friday Aug 26 TIS meeting, bNMR is very satisfied with the beam; the count rate is very stable.

Thu Mar 31 15:19:51 2011:  SiC#25 was made sometime in December of 2010.  It is now in the target module and ready to be conditioned. 

Mon Apr 18 18:17:05 2011: It was found later that no salt was added to this target after it came out from the test stand.  However,  there were enough 40Ca and 39K  for tuning (See attachment#1 for the big mass scan).  Once the P+ is back, the yields will be measured.

Fri Apr 29 15:30:26 2011:  Low 27Al was ionized from the surface for some reason.  However, after the green laser was shone into the extraction tube, more 27Al was produced.  Then, the laser was turned off, the target continued to surface ionizing 27Al.  There could be a blockage from the rhenium (Re) ionizer foil.  Jens L. will investigate this further and do a test with the lasers and the rhenium foil.

Thu Apr 7 15:32:32 2011:

Target oven - w.o#38481-3.

Packs of Ta foils were previously prepared by Vicky H.

Marik loaded the target:  400 of 0.025mm foils (25 foils/pk) in 3.5cm length.  (Recommended length 4.0-4.5cm; If too closely packed, wires get squeezed and snapped)

Average mass per discs = 0.105g

Total mass (Ta+wire) = 45.06g

Disc area = 2.12cm2

Ta thickness = 21.25g/cm2

Thu Apr 28 :

Target heat Shield (w.o 38303-4) cleaned

Target is now assembled by John and Rick

Megger Test Performed:

TA-->HS = 540V, OL

TA-->EE = 540V, OL 

HS--> EE = 1049V, OL

Leak Check OK

*SIS restraint used in this target ion source

Mon May 9 10:32:40 2011:  Standard salts added: Li, Na, Rb @ 10uL, K @ 5uL (but added 10uL), Cs @ 15uL.  Target will be going to the test stand.

Fri May 20 16:57:22 2011: 

Target was tested on the Test Stand but problems with the software (see Test stand elog). 

Standard salts added: Li, Na, Rb @ 10uL, K @ 5uL (but added 10uL), Cs @ 15uL, and Be @ 10uL.

Monday, July 18, 2011, 11:15:  Target ended on July 16.  The target was used online for an extra 2 weeks and performed very well.
