Just pushed out the 'full' cooldown gui. Still need to update the corresponding alarms gui though..

Hello Ruben, 

Calculation to estimate temperature in the Coils 1 to 5 are completed, the calculation were implemented in the Solenoid PLC code and EPICS screen as well (See attached screenshot). Actual readout values are not the expected values, since we need to hook the Solenoid to read normal parameters that are involve the calculations for the estimate temperatures. 
Detailed information of this calculations and results can be found in the spreadsheet Standard Length_Solenoid_cond_for temp estimation_June 15th_ 2017_V1 in the next link: M:\hallb_eng\CLAS12\Magnets\Solenoid\Controls and Wiring. 

Best Regards, 
Pablo

Hi Ruben, 
Pablo will send the details and the screen shot of the EPICS screen today (15th June). 
All completed but will test only after hooking up the magnet and MPS. 
Pablo - could please send the document as suggested and the location this morning. 

Regards 
Probir

Probir, 

What was the outcome from your meeting today? 

Is the work now complete with EPICS screens updated?
