I got the temperature interlock box from Mark Taylor on Monday. Six RTDs have been plugged in, since one box has six temperature modules, and the other box is in the Hall reading out the target cell and refereence temperatures.
This box has not been interlocked to the lasers yet. The temperatures read <10 °C on four of them. One shows 21 °C and the sixth one reads OPEN. Shall investigate.
The present set-point to shut the lasers is 28 °C. The RTDs are
placed on the cylinders of each leg of the 5-to-1 combiner.
