Pumped on supply U-tube all weekend, but the biggest effect happened on Friday afternoon when I changed the setpoint of EV8611JT-Min to 5.8K
Flow to Hall B peak to peak was ~1 to 13 now 3-7 g/s
LL of solenoid was 75 to 100 now 78 to 82%
Supply temp to solenoid was 5.7 to 50 now 5.6 to 13K
Return temp from solenoid was 7.5 to 35 now 8.5 to 10K
Supply JT to solenoid was 44 to 70 now  45 to 62%

A plot of the key parameters of the solenoid is attached. All signals are plotted with  range of 500 from  min to max on the graph.

Lowered set point of EV8611JT_Min PID from 5.8 to 5.75 to see if any more stabilization can be achieved
