Minutes

Present: Dave, Mark S., Scot, Orlando, Hovanes, Elton, Nerses

BCAL pulser

• Orlando showed the status of the BCAL pulser control.
• The application is pretty much ready to be used.

Alarms for voltages

• Nerses is working on the scheme to generate alarms for voltages in EPICS.
• He showed the logic he is currently considering.
• There was a suggestion to have an alarm when the voltages are set to be off, but they are still on,
• Orlando pointed out that there will be a delay between the moment the setpoint is set and setpoint is readback. This time delay needs to be taken into account.

BCAL interlocks

• Dave reported significant progress on the BCAL interlocks .
• Upstream is wired and tested. Downstream interlock is in progress.
• Downstream chiller is not connected as of today. Will be connected most likely by the end of today.
• Buttons need to be change to match Elton's convention .
• Hovanes asked Elton if the expert GUI that Dave has will need to be copied to EPICS or EPICS will need to have only a GUI for the shift personnel with very limited personality. This was followed by a discussion about the need to have a PLC in the counting house.

Radiator stage

• The test were done by Yi and Hovanes. The stage satisfied the specs. The limit switches will have to replaced.
• Slava and Hovanes handed the stage to Tim for installation on the tagger hall. The PS converter stage is in the FEL now.

Cabling of the motors

• Tina has been working on the cables for the Hall D motorized stages.
• Collimator cable will be complete today.
• Scot needs the notation for the low and high limit switches for each stage.

Gas system controls

• Gas system is pretty close to be complete.
• Procedures are being circulated for the controls.
• Dave reported that 80% of the PLC GUIs are complete.
• Michael Staib from CMU is working on the EPICS controls screens for the gas system .

Other

• Elton would like to purchase flow meters with remote readout. He will send an e-mail with the data-sheet or the specification for the flow-meter he liked.

Action items

• Hovanes will send info to Scot on limit switches for motors.
• Beni will forward Hovanes the draft of the procedures for the gas system to Hovanes.
• Dave will change the buttons on the BCAL temperature GUIs to match Hall D convention for controls buttons.
• Elton will send an e-mail with the information on the flow meter.
• Dave will check if the flow-meter that Elton wants could be easily integrated into the PLC controls.
• Orlando will commit the final version of the BCAL pulser control and Hovanes will check out the GUIs on the official tree.
