UCx#2 Spec:

Target wrapped with 3 Ta-heat shields

Target length = 11.2cm

Total UC2/C foils = 245 discs

Total U/cm2 = 15.27g

Standard salts = 10uL Na, 10uL Li


Tuesday, August 09, 2011, 14:27: 

Target came out from the glovebox and transported to the cold lab for assembly.  During the assembly, one of the screw-heads for the heat-shield broke (see attachment#1: broken_screwhead). 

The target was leak checked and fine. 

Target is going back to the glovebox to be kept under Ar until RH is ready (see attachment #2: UCx#2).

UCx#2 run was finished last week.  

Target was moved from ITW to south hot cell, and stored in a bucket under argon feed.

The target is now in the test-stand, and by next week Tuesday, it should go in the Hotcell.

 


 Monday, June 04, 2012, 16:56

The target was tested in the Test-stand.  The EE was inspected and a small amount of deposit was discovered after the test (the same stuff was found on Ta#36),  see attachment #1.  The samples were collected and will be analyzed through SEM/EDX/XRD.

The EE and the common plate were cleaned with methanol and were assembled back.

The target is ready to go in the Hotcell tomorrow, June 05.


 Monday, November 05, 2012, 16:42

The deposits on the EE and CC were analyzed using XRD

On the EE, it was mainly copper hydroxide nitrate, Cu2(OH)3(NO3). (see attachment #2)

On the CE, it was mainly tantalum, Ta. (see attachment #3)

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.

  • The target can not hold high voltage when it is sitting on the jig. The insulator on the jig have reduced resistance over time (less than 1 G Ohm). All high voltage tests passed when target is tested not sitting on the jig.

 

  • Target is now in the test stand and pumping down.

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.

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).

Waste accountable for UO2 = 12.57g

 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)
