SSR1- Sensitivity to He pressure variations

SSR1 must operate within a small bandwidth plusmn 20 HzPressure of LHe can vary by plusmn 05 Torr in the cryomoduleA self-compensating design was developed allowing low sensitivityDespite non-negligible deformations (see picture) net shift is very low thanks to Slaterrsquos TheoremBare cavity ~ 600 HzTorr with He vessel ~ 10 HztorrEase of tuning 39 NkHz (bare) 40 NkHz (with He vessel)

SSR1 must operate within a small bandwidth plusmn 20 HzPressure of LHe can vary by plusmn 05 Torr in the cryomoduleA self-compensating design was developed allowing low sensitivityDespite non-negligible deformations (see picture) net shift is very low thanks to Slaterrsquos TheoremBare cavity ~ 600 HzTorr with He vessel ~ 10 HztorrEase of tuning 39 NkHz (bare) 40 NkHz (with He vessel)
