To bring the oven temperature up to the desired 175C, Ed Folts and his crew added a second heater in front of the main oven heater element. It is powered by a variac sitting on a table to the right of the laser hut door. The variac is currently set to 65V.
After 1 hour of heating, the oven temperature is stable at 175+/-1C. The air flow is 240 units and the heater temperature, 76C. The heater temperature interlock setpoints were increased to 90C.
We informed MCC at 16:15 that work in the Hall was finished. Lockup is expected between 17:00 and 19:00.
