UO2/C green was prepared on May 2, 2013 and let dry over the weekend.
UO2 powder used = 50.36g (Inventory R-00835A UO2 + bottle = 896.30) |

UO2/C green was prepared on Aug 17, 2013. The slurry was cast on a piece of glass coated with WD40.
The cast was let dry until Aug 19, 2013. |

A P2N target was carbothermal reduced but at the maximum current, the power supply tripped (elog. 267)
Therefore, the target was not hot long enough to fully outgas, that is why it will be reheated. |

The assembly consists of two tantalum foils, 0.001" thick, which are radially crimped to form a cylindrical surface. The outside support are
two P2N conditioning legs, and the inside supports are tantalum tapered rings. The solidworks geometry for this test is ITD0811 in PDM.
The
P2N is attached to EVAP1 with copper legs and copper shims. A current ramp up to 600 A on the target wrapped with heat shields is attempted to benchmark |

Yesterday, a second graphite cartridge was installed in EVAP1, it consists of the old, 3-body cartridge design, and was sanded on the outside to
be able to fit a P2N container. |

Wed May 18 13:12:24 2011: Target is wrapped with 3 Ta-heat shields and is installed in the evaporator which is being pumped down.
Wed May 18 23:11:42 2011: TGHT was raised to 40A and held for about 6 hours; Vac gradually came down to 2.1e-6 Torr. TGHT increased
to 90A and pressure is going up, currently vac @ 2.9 e-5 Torr. Auto heating will begin soon at 0.5A/min --> 820A. |
