本文扼要介绍了稀释制冷机的原理,较详细地描述了DRl00-10稀释制冷机的制作,调试和性能.多次运转表明该机能达到的最低温度为33—40mK,在100mK时的制冷量为24μW,He~3的循环量约为50—100μmole/sec.最后对该机作了粗略讨论,提出了改善性能的可能性.
This article briefly introduced the principle of dilution refrigerator, described in detail DRX00-10 dilution refrigerator production, commissioning and performance. Multiple operation shows that the machine can reach the minimum temperature of 33-40mK at 100mK when the cooling capacity of 24 μW, He ~ 3 circulation is about 50-100μmole / sec Finally, a rough discussion of the machine made the possibility of improving performance.
