Description
The diverse and challenging requirements of dark matter searches motivate the development of new readout technologies. Relevant performance metrics include input noise, frequency range, bandwidth, resistance to magnetic field, and compatibility with a variety of sensors and sensor architectures. In this presentation I describe work at NIST on several superconducting readout technologies relevant to dark matter searches. These include the microwave SQUID multiplexer, parametric amplifiers, and Kinetic Inductance Current Sensors (KICs). Some of these devices have already been used in dark matter searches while others show potential for future experiments.
