The average mass per disc = 0.105g

Total mass (505 discs + some Ta wire for packing) = 53.876g  ( Not 75.277g as mentioned above.  See Target Logbook 2015 Dropbox for more details)

 Target full name ITE-TM4-UC#31-P2N-SIS

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).
