We report on a cryogenic ion trap apparatus for quantum information processing and quantum simulation experiments with 9Be+ ions in surface-electrode ion traps. The ion trap is cooled by a vibration isolated closed cycle cryostat to reduce the detrimental effect of anomalous motional heating. We characterize the vibration isolation using a Michelson interferometer and find residual vibration amplitudes <20 nm 0-pk. We report on the setup of the cryogenic shields and thermal management for bringing in a large number of DC and RF control signals. We present the trap RF drive based on a miniaturized cryogenic helical resonator and discuss its performance.
