UO2/C green was prepared May 6, 2015. The slurry was cast on a piece of glass coated with WD40 on May 7, 2015.

The cast peeled off the glass nicely May 8, 2014 and finished drying over the weekend. [see attached picture]

Some materials were stuck on the WC jar wall and balls, consistent with every time.

Initial UO2 powder used = 50.44g (Inventory R-00835A, UO2 + bottle = 444.23g before use)

Graphite powder used = 10.05g

Green cast dried UO2/C + organic mass = 61.23g

The green was rolled up and wrapped in a piece of graphite sheet.

The Ta-target boat is wrapped with 3-layers of heat shield and installed in Evap1.

Chamber is currently being pumped down.

Target boat will be ramped up to 520A at the rate of 0.1A/min

Vacuum limit stop at 5.0e-5 Torr, backing off at 6.0e-5 Torr.
