Abstract

A microcalorimeter with the superconducting transition edge sensor (TES) with a Au absorber of 5.0 μm thick was fabricated for the energy dispersive measurement of LX-ray photons emitted from transuranium elements. The TES microcalorimeter and a superconducting quantum interference device (SQUID) amplifier chips were cooled by operating a compact ³He-⁴He dilution refrigerator without consuming liquid helium by loading a Gifford-McMahon (GM) cooler. Since the cold stages of the GM cooler are tightly coupled to the heat exchangers of the dilution refrigerator, the TES and SQUID chips suffered from mechanical vibrations induced by a reciprocating motion of the displacer of the GM cooler. Detection signals of LX-ray photons emitted from an ²⁴¹Am source were observed by operating the TES microcalorimeter in severe noise environment induced by mechanical vibrations.
