35 circles of 14 mm diameter were packed into a graphite sample container.
28 discs corresponded to cats#1 and 7 discs to cast#2
35 x UO2/C circles = 3.42 g
Graphite container = 6.96 g
Graphite tube is placed inside a target boat.
Boat previously coated with TaC and sintered.
Ta-target boat is wrapped with 3 new Ta foils for heat shielding and the boat was installed in Evap1.

Initial IGP1 = 4.82x10e-7 Torr
Tapped up entire process manually to 520A in 30 min
TGHT = 520 A, 5.63 V
Vacuum coming down nicely indicating carbonization process complete
Will remain at max setpoint for 4 hrs to ensure full carbonization before cooling down.
