Logentry Text:
In an effort to refine the procedure to burp the Torus and keep the Solenoid cold (and buffer dewar cold) this afternoon I will be making small changes to the Solenoid 4K supply valve controls. I expect no more than 1-2 g/s flow change to the Hall. If anyone notices a negative effect please call my Cell 757-876-3265

The main change is to lower the set point of EV8611JT_Min (the cascaded PID) that controls the flow through the solenoid based on Solenoid return temperature in the DBX TD8522SR.
