Mass of empty target oven used = 461.55g

Target oven filled with 402 discs of UO2/Nb, 5.0cm in length, and tot mass (before sintered) was 61.49g (UO2+Nb+org). 

Target finished the sintering process on Feb 20, 2011.  

U(402 foils) mass = 35.689g

U(402 foils) thickness = 16.834 g/cm2

Target is stored in the Hotlab and ready for assembly.

Some notes about the target conditioning in Evap#2 (see elog ID#414):

TGHT at 500A, 8.4V, temp at 1600 C (4.2 kW)

TGHT at 475/7.84V, temp at 1550 C (3.72 kW - Max operating target heating power)

TGHT at 450/7.31V, temp at 1500 C (3.28 kW)

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).

Total no. discs = 422

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.

Target is currently undergoing the sintering process

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).

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...

Three Ta heatshields left installed on container.
