TGHT will be ramped up to 300A at 2.0A/min. Final desired temperature = 1900C Friday, October 14, 2016, 13:28 TGHT and TBHT had reached 300A/ 230A respectively. Power bump ~10min ago caused evap2 to trip off. Tapped back up manually to 35A. Re-initiating auto ramp now.   Friday October 14: the target was ramp up to 300A/230A after Laura started it. Then, I cooled down at 6pm before leaving TRIUMF. <br> Saturday October 15: restated the auto-ramp for Ta#50 in EVAP2. It's currently set to go to 300A/230A.  Sunday October 16: the target temperature measurements up to 620A/230A were performed today not on October 15 (yesterday, it was cooled down before reaching 300A/230A). Currently the target is cooling down, to be ready tomorrow morning for the Test Stand.

Vented in air and taken out this morning.

Target looks good!
