This is the graph of the leak test of Solenoid Coil #1 on January 31, 2008. (It shows the coil is leak free.) The test was done with a Inficon Helium Mass Spectrometer Leak Detector capable of detecting leaks in the 10-11 Std. cc of He per sec. The graph shows that once the Detector is "zeroed" to eliminate a background of 10-8 Std. cc of He per sec, only noise between 10-12 and 10-11 is seen during pressurizations to 15 psig in first, the Shield's LN2 circuit and then in the coil's LHe vessel. The opening of the 5 x 10-8 calibrated leak shows the sensitivity of the test system. The test was performed by Elliott Smythe of the Accelerator Vacuum Group and John Fischer of the SRF Assembly Group. The leak detector is calibrated with its own internal leak by its automatic calibration routine.
