[dsg-hallb_rtpc] [EXTERNAL] Leak tests on the floor of Hall B

[Brian Eng]

Correct.

Just turn off the supply and disconnect the cable from the MFC end on the one that is currently connected.

Hi Brian,

I guess you are saying this one.

Thank you,
Jiwan

Hello Brian,
   Will you be available to help with it tomorrow morning?

Thanks
Mohammad

In that case there is a bench top power supply and cables (15-pin DSUB to flying leads) located in EEL/231 (in the area immediately to the left against the wall close to the CAEN crate) that can be used to power an MFC.

Then you'll just need to figure out where best to get networking from as I don't know what's available on L0, perhaps Sergey or Nathan knows?

Make sure you can ping the MFC after reconnecting and then reinitialize it via the button on the GUI.

Hello Brian,
   Yes, all what we need is the MFC and the local readouts. We cannot keep moving it forth and back to SFL1 after every sealing iteration. The process may take three iterations. It is not needed for today, but mostly tomorrow.

Thanks,
Mohammad.

Hi Mohammad,

I've added Krister to the CC list as he also worked with running the cable.

Honestly I'm not sure we have a long enough cables to reach from the current cRIO on SFL1N to L0 on the floor, there's some slack to allow for cart movement, but not that much.

In theory the cRIO itself could be moved to the floor since all it needs is power/networking, however it would be a rather huge undertaking to try and decable the cRIO rather than just move the detector back to SFL1.

The power to the MFC could be supplied from an external supply located near the panel, but the sensors themselves need to go to the cRIO. Is just the MFC + local readout sufficient for your testing?

Hello Brian and all,
    I am reaching you to ask about connecting the MFC to the Labview software. We observed major leak from our detector and we moved the detector and the gas panel to the floor. We need your help in connecting the MFC and the pressure indicators to the software to control the gas and watch the building pressure. Can you help us with this?

Best regards,
Mohammad Hattawy.
