CCAT: LED mapping of the 850GHz instrument module for prime-cam on FYST

Le résumé fourni par la source

Prime-Cam, one of the first-light instruments for the Fred Young Submillimeter Telescope developed by the CCAT Collaboration, will accommodate seven modules, including a central 850 GHz camera. The 850 GHz module uses three arrays of TiN microwave kinetic inductance detectors (KIDs) totaling roughly 38,000 detectors, read out through 12 RF feedlines per array. As part of the characterization pipeline, we perform LED mapping to relate each detector’s measured resonant frequency to its physical position on the wafer. This enables a lithographic trimming step of the KID capacitors that significantly reduces frequency collisions and boosts usable detector yield. We present the design and laboratory characterization of one of the 850 GHz TiN arrays, with emphasis on the implementation, performance, and accuracy of the LED-based mapping procedure.
