We are developing of adiabatic demagnetization refrigerator for X-ray microcalorimeter operation. By improving thermal environment in the cryostat, it achieved the lowest temperature of 80 mK, temperature stability of 9 μK rms at 100 mK, and a hold time of 7 hours at 100 mK. The excess heat load to the saltpill decreased from 10 μW to 3 μW. Using this system, we demonstrated a measurement ofR–Tcurve of a TES microcalorimeter andϕ–Vcurve of a SQUID.
