SN0932 was annealed between 02 and 03 September 2021 - used the large furnace in Downs 221, atmosphere was air, used glass petri dishes to protect optic (from Gabriele and CRiMe).
Ramp up rate = 100 °C per hour
Hold temp = 300 °C
Hold time = 10 hours
Ramp down rate = 100 °C per hour
Witness RTD observed a ~22 °C overshoot and ~14 °C offset from controller RTD. See attached image (.xlsx file is source document).
Optic is now with Liyuan in RTS for recharacterization after anneal.
