High-efficiency and Low-noise Detectors for the Upgraded CLASS 90 GHz Focal Plane

High-efficiency and Low-noise Detectors for the Upgraded CLASS 90 GHz Focal Plane

We present the in-lab and on-sky performance for the upgraded 90 GHz focal plane of the Cosmology Large Angular Scale Surveyor, which had four of its seven detector wafers updated during the austral winter of 2022. The update aimed to improve the transition-edge-sensor (TES) stability and bias range...
