Cryogenic LED pixel-to-frequency mapper for kinetic inductance detector arrays
Cryogenic LED pixel-to-frequency mapper for kinetic inductance detector arrays
We present a cryogenic wafer mapper based on light emitting diodes (LEDs) for spatial mapping of a large microwave kinetic inductance detector (MKID) array. In this scheme, an array of LEDs, addressed by DC wires and collimated through horns onto the detectors, is mounted in front of the detector wafer. …
