Note:

This target was built in 2011.  The endcaps were replaced after they got vaporized in Evap#1 during the sintering process, and the target was re-conditioned.

See elogs for more details:

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. 

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.

• 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.

After the test-stand, the extraction electrode showed some electric arcing mark, but no solid deposits were found.  (see attachment#1: EE_after_teststand.jpg)

See attachment for the target specification.  

Details about Ta Hp surface, w.o#38295-4 (spare):

This target was built as a spare.

Note: Left side target arm replaced, Nov 18, 2010.  Weld prep on centre block misaligned.  (Marik has more details about this).

Packs of Ta foils were prepared by JW. 

Target was filled with 400 of 0.025mm foils (25 foils/pk) in 4.0cm length. 

Total Mass of 16 packs of Ta foils + Ta wires = 42.70g.  

See attachment#1 for the measurement.

Target was tested at the Teststand.  Result Good. 

Ready for use.

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).

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 

 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.
