[dsg-hallb_gas] ALERT in Clean Room

[Bob Miller]

Hi Denny,

Please install a full K bottle of 80% Helium / 20% CO2 in the clean room.  Turn on the bottle when finished so ALERT can continue their testing.

Thanks,

I checked it yesterday, it was bubbling.

I just checked the system, the MFC is set to 15, but there is no flow and the MFC valve is at 100%.

So, I think the tank may be empty.

Bob, can hall b have the bottle changed out?

Marc

Thank you!

Could you check the bubbler?

Hi Gabriel,

I set the flow to 15 L/h, per your request. I'll check the bubbler when I go in this morning.

Hello Marc,

 If you have time today, could you set the gas flow of ALERT HDC to 15L/h please? It should be bubbling inconsistently but still bubbling.

Have a nice day,

Hi Marc,

 Thank you, then if it is not too late, you can close it for the weekend and I am not sure we will turn it on on Monday.

Have a nice weekend,

Hi Gabriel,

In the short term, while we are working out the details of remote control of the system. If you send me an email, I can set the MFC flow remotely.

Hi Bob, hi Marc,

 I wanted to thank you again for the nice work.
 The gas system works very well and its use could not be better. The interface to control is beautiful also.

 One question, can I access it via clascss? Eventually it will need to be there I guess if the other gas control panels are controled via clascss. If not, then I'd be curious to know how the other detectors are doing.
 In any case, while it is in the EEL building, is there a way to access it remotly? That would prevent unecessary use of gas when we are not trying to take data.

Have a nice day,

Hi Bob and Marc,

 Thank you both for your work. Everything is very nice.
 I'm travelling on Monday and will hopefully be allowed to work on Tuesday afternoon in the clean room.

 Where or how can I find you?

Have a nice day,

Hi Bob,

The gas flow controls are set up for testing in the clean room (EEL124).

We can meet Monday to go over operations, but the only control is the mfc set point.

Hi Gabriel,

The gas panel and scintillators are installed in the clean room along with the electronics rack.

We can purge the gas system next week before connecting it to the DC.
