Description
We are developing X-ray microcalorimeters using superconducting transition edge sensors (TESs), which can be operated at relatively high temperatures in a 3He cryostat, and DC-SQUID current amplifiers to realize an X-ray spectroscopy with a high energy resolution and a high counting rate. The TESs are proximity bilayers of Ti and Au on SiNx membranes with 500-1000 nm thicknesses. The typical TES has a Tc value of 0.4 K and a ΔTc value of 2 mK. Two types of DC-SQUID amplifiers were developed; the single stage with 200-series SQUIDs and the double stage with an input SQUID and 50-series SQUIDs. The X-ray detection experiment is in progress.
