我们正在研制用于X射线微量热计工作的绝热退磁制冷机。通过改善恒温器的热环境,使恒温器的最低温度达到80 mK,100 mK时的温度稳定性达到9 μ Krms,100 mK时的保持时间达到7 h。对盐丸的过量热负荷从10 μW降低到3 μW。利用该系统,我们测量了TES微量热计的R-T曲线和SQUID的R-V曲线。
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.
