The Axion Dark Matter Experiment (ADMX) clinic project is sponsored by Lawrence Livermore National Laboratory (LLNL) to develop a piezo-electric rotary drive system. This drive system will move tuning rods within a microwave cavity to adjust the cavity’s resonant frequency as it scans for signatures of axion dark matter. The system must be able to operate with heat generation on the order of 100 microwatts or less at 0.1 K in an 8 T magnetic field and 10-6 Torr vacuum.
