* The ST-100 should not be baked out because the window block and electrical feedthroughs are sealed using epoxy and baking out the cryostat might cause the epoxy to melt.
* What we've seen is that at room temperature while continuously pumping with the [[Turbo Pump Station (HiCube 80 Eco)|Pfeiffer turbo pump]] the pressure is pretty constant around 5.6<math>*10^{-5}</math> mbar (~4.2<math>*10^{-5}</math> Torr). While the cryostat is held around 5 K and continuously pumped down, the pressure gets as low as 4<math>*10^{-8}</math> mbar (~3<math>*10^{-8}</math> Torr).
