A Tunnel Diode Oscillator for High Sensitivity Broad Temperature Range Susceptibility Measurements
A. Sirusi, J. Adams, M. Lewkowitz +2
We report the design and operation of a versatile tunnel diode oscillator for high sensitivity (50 ppb) measurements of the magnetic susceptibility of samples over a wide temperatu…
Towards 100,000-pixel microcalorimeter arrays using multi-absorber transition-edge sensors
S. J. Smith, J. S. Adams, S. R. Bandler +15
We report on the development of multi-absorber transition edge sensors (TESs), referred to as hydras. A hydra consists of multiple x-ray absorbers each with a different thermal con…
First Operation of TES Microcalorimeters in Space with the Micro-X Sounding Rocket
J. S. Adams, R. Baker, S. R. Bandler +20
Micro-X is a sounding rocket-borne instrument that uses a microcalorimeter array to perform high-resolution X-ray spectroscopy. This instrument flew for the first time on July 22nd…
Micro-X Sounding Rocket: Transitioning from First Flight to a Dark Matter Configuration
J. S. Adams, A. J. Anderson, R. Baker +21
The Micro-X sounding rocket flew for the first time on July 22, 2018, becoming the first program to fly Transition-Edge Sensors and multiplexing SQUID readout electronics in space.…
