Lessons Learned – Use of RGA Quadrupole Mass Spectrometer for Leak Detection
Year: 1996
Abstract: Description of Driving Event:
On the MIDAS project, leak detection for the vacuum chamber was done both by helium "sniffing" using the RGA, and also by checking the N2 to O2 ratio to see if there was a steady air leak present. In one case, this ratio did not indicate a leak, because the cryopump was preferentially pumping oxygen.
