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.

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.

First batch of UO2/C mixture of carbonization (Stock# 2011_A):
UO2 used = 50.120g (left overs + container = 411.23g)
C(grv) used = 10.653g (or 21.25% w/w)
Mass of organics = 4.842g (or 9.66% w/w)
Mass of dried cast = 47.420g
Waste collected in jar = 18.195g (including UO2, C and Org)
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

- Cu-gaskets used for leak checking target had a leak rate of about 10-8 10-9 atm cc/sec. Replaced with silver plated SS gaskets and no leak detected above 10-11 atm cc/sec.
- 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.

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.

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.
