Monday, April 15, 2024, 14:33: On Friday it was noted that the EE was being troublesome. If we put -500 V on the EE the PS would deliver -1000 V. However
it would slowly trickle downward. elog:1002.

Opened the ATTS, placed what I will call “Cast Alumina Sample #1” into the ATTS and activated the roughing then turbo pumps. Currently sample
is in slow heating progress to 1000 degrees Celsius, process is expected to take some time, so I'll revisit after lunch.
