Previously sintered over weekend [see elog i.d 311]
Target container contains 471 discs of SiC [6 x 5 packs + 441 single discs]
Target packed length = 16cm.
Mass of 533 discs SiC(green) = 52.7172g
Container is wrapped with 3 heatshields; no end caps are inserted yet - coated spring inserted both sides to hold discs in place.
Conditioning temp = 1800C.
TGHT max = 450A. TBHT max = 230A.
Chamber is currently being pumped down.

Target was not removed from evap2 after sintering, vented and cleaned windows only.
IGP1 = 5.5e-6 Torr
Stepped up manually to 80A, vacuum stable.
IGP1 = 3.2e-6 Torr
Initiating auto-ramp at 0.2A/min for the TGHT and 0.1A/min for the TBHT.

Tues the TGHT reached ~280A via auto-ramp
Evap2 was then tapped up manually to 480A/ ~1800C
Temperature readings on OMEGA have fluctuated up and down during conditioning process which was also observed for SiC#33
Also consistent with SiC#33, a lower current was required to reach 1800C during the conditioning process compared to the sintering process.
See attached link for data.

TGHT remained at 480A, 9.2V for ~7 days.
IGP1 = 6.5e-6 Torr
OMEGA = 1470C [with window coating, so temperature reading compromised]
Initiating auto cool at 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.

Vented in air and opened this morning.
Target broke 
Target clearly heated to high.
See attached snapshot of striptool from conditioning process.
Will update later with photos of broken container
