[Halld-controls] Hall D controls meeting on July 12, 2018

[Scot Spiegel]

Hovanes, 

Do you have the motor driver card for ComCal vertical stage? I'm planning on terminating the control cable (25 pin d-sub) @ the driver controls rack today. 

Tim, 

Do you have an idea about the type & mounting for the limit switches needed for ComCal? I would like to order them A.S.A.P. 

Best regards,

Hi Hovanes, 

As usual, I have the DIRC meeting at the same time and will not be able to attend the controls meeting. Here is some input; 


    * Solenoid status (Tim,Beni,Brian) 
        * ADC calibrations 
        * Hot check out to begin last week in July 
        * Helium LL probe Dewar test today 
    * Goniometer (Tim, Hovanes) - removed jd70-100 diamond and will cycle all stages to distribute grease 
    * 
    * ComCal 
        * Translation stages (Tim, Hovanes) - Nema 23 motors ordered, Vertical stage ordered, need limit switches for vertical stage 
        * Voltages (Hovanes, Nick) 
        * LED pulser (Hovanes) 
        * Temperature monitoring and chiller ?? - BCAL spare chiller will be used - adding flow meter same as BCAL. 

Please let me know of any questions or comments. 

Thanks,
