Abstract

HUBS adopts microcalorimeters based on transition edge sensors (TES) as its sensitive detectors, requiring an energy resolution of 2 eV or better. In the project’s development phase, various Mo-Cu TES microcalorimeters have been fabricated in our lab, based on different designs. In this work, we will describe the measurement system built in our lab and show the preliminary results of a TES, including various electrical and thermal properties. We also tested the energy resolution of this TES with a laser diode system, and the resolution of the TES is shown to be 0.34 eV.
