Abstract

We describe the design of a reusable indium wire seal which has a small profile and is leak tight to better than $1 \times 10^{- 10}$ std. cc/s from room temperature down to ≈ $50 mK$ . The pressure necessary to deform the indium wire o-ring is provided by a screw-cap mating to threads on the outside of the cylindrical volume to be sealed.

The CF seals are used at all other positions in the CAPR UHV system except the windows. Furthermore, the CF seals allow for baking up to 450 °C [11], although in certain regions indium limits baking to 100 °C [12]. The Molflow + package [16] is used for Monte Carlo simulation.
We present the design and testing of the ultra-high vacuum (UHV) system, which is a key apparatus for the Cold Atom Physics Rack (CAPR) operated on the Chinese Space Station that allows study of ultracold atoms in microgravity. The simulation of the gas flow and experimental tests show that our UHV has a pressure of $3.4 \times 10^{- 9} Pa$ in the science chamber, two orders of magnitude lower than that of the 2D magneto-optical trap (2D-MOT) chamber. Moreover, we demonstrate that the system can not only self-sustain an equilibrium pressure for more than 1 month without power but also restore the desired pressure in the interaction zone. The loss dynamics of the trapped atoms are also measured to assess the performance of the UHV system.
