Towards a cryogenic vacuum system for rapid testing of ion traps

We present on progress towards a cryogenic trapped ion system for rapid and iterative trap testing. The low vapor pressures of nearly all substances at cryogenic temperatures (<10 K) allow for low vacuum pressures to be quickly realized. The cryogenic stage to which the ion trap is thermally anchored is designed for convenient trap replacement. The design is partly enabled by the wider range of materials that will not outgas due to cryopumping. We plan to take advantage of other features of the cryogenic environment, such as the use of superconducting rings to reduce magnetic field fluctuations, see X. Wang, et al., PRA 81, 062332 (2010).
