Maintenance of MEG system
Checks to be made
Helium level
Every two days check Helium Level it should be higher than 50%
- Check the ATP and ATL gas flow and pressure
- If low Helium pressure (Low G FLOW on the ATL) then
Remove the hose between ATP and ATL
Check if helium is passing through the hose
Plug the hose again, see if G Flow increases
Restart the ATL from the green button on the rear panel
Data retrieval from ATP and ATL for diagnostic
When the ATP and ATL helium recovery system exhibits low gas flow or unusual temperature/pressure, contact the references below and provide them the following data
Retrieve data from ATP and ATL by opening an FTP connection to 10.224.44.200 and 10.224.44.201
Connect to the NYU Abu Dhabi VPN
Use the following information username: qd, password: 79653
Navigate to the /StorageCard/DAT_Files/ directory for each of the previous IP addresses, send the latest .dat files
Note
documentation in the link: QD Documentation for Data retrieval Sheet to be filled by maintenance team for Helium levels Helium Filling Sheet
Check air pressure every month
The air pressure inside the meg can be not so good, it must be 0.7, 0.8 this could be a compressor problem
When the air pressure is low, the door could be stuck
MSR Door:
Test the emergency button every week
Test if the pressure release when using the emergency button is getting heavier or not releasing pressure as it is supposed to be
If using the manual handle, make sure that to reset the door, you need to put the handle in the original position or else the door won’t reset
