UO2/C green was prepared Jan 20, 2015. The slurry was cast on a piece of glass coated with WD40 on Jan 21, 2015.

The cast was let dry over the weekend and peeled off the glass nicely Jan 26, 2014. [see attached picture]

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

Initial UO2 powder used = 50.32g (Inventory R-00835A, UO2 + bottle = 494.52g before use)

Graphite powder used = 10.02g

Green cast dried UO2/C + organic mass = 60.33g

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.

change of plan.

there will be several interruptions over the course of the next month including a planned power outage and water shut off.

therefore UO2/C cannot be carbonized as these interruptions  will trip off the system when UO2/C would be at max temperature.

EVAP1 is now turned off and the flakes will be stored in the fume hood until further notice.

EVAP1 has been cleaned.

Target boat has been reloaded into evap1 and currently pumping down.

Will initiate ramp up tomorrow.

IGP1 = 1.7e-6 Torr

Tapped up manually to 35A.

Waited ~2hrs, vacuum stable.

IGP1 = 9.7e-6 Torr.

Initiating auto-ramp.

TGHT reahed 520A, 5.78V on the weekend.

The boat has been sitting at max setpoint for 4.5hours.

Carbonization process is complete [See attachment].

IGP1 = 3.4e-6 Torr.

Initiating auto-cool at 2A/min.
