[Dsg-halla_gas] Notification for connection of gas supply on UVa GEMs in Bigbite in TEDF

[kagnanvo]

Dear Jack,

The Marc Mullen from DSG group has just set up the SBS gas system 
prototype for us in the TEDF highbay area to try it out on the UVa GEM 
layer we just recently installed in Bigbite frame.

We would like to notify to that we are now ready to connect the gas 
supply to the GEM chambers and seek your approval to proceed.

We are planning to use a gas cylinder and regulator system identical to 
the one we have installed for the commissioning of the UVa GEM layers in 
EEL124 clean room and set up for us by Chuck. This system will be hooked 
up to the monitoring system installed by Marc to supply the BB GEM 
chambers.


Please let us know if there is any step we need to take before going 
ahead with connecting the system to our chambers. Ideally we would like 
to have N2 flowing into the chambers before the xmas break


Best regards

Kondo
