Paper Abstract

Transition Edge Sensor (TES) quantum microcalorimeters can provide intrinsic arrival time and energy resolved measurements of individual photons over a large energy range centered on the optical band. Our TESs consist of thin-film superconduting tungsten pixels on a silicon substrate. The pixels are voltage-biased to remain in the sharp superconducting transition region through negative electrothermal feedback. We report progress on our first imaging TES array of 32 pixels. We describe the experimental apparatus, summarize recent progress, characterize detector performance and outline the future path of TES development.
