论文摘要
我们在这里提出一个小型液态氦（LHE）浸入式低温恒温器，具有适用于长波长辐射范围和施加的磁场下的创新光学设置。低温恒温器是一种多阶段设备，除了几个光学阶段外，还具有多个屏蔽。该系统已使用外部液体氮锅炉设计，以减少液体气泡。计算并优化了针对设计的配置的光学元素的光学和机械性能，而光学布局已根据设备的几何形状进行了模拟和优化。最终设计已针对在波长范围内应用磁场下的接近连接阵列的低噪声辐射测量进行了优化，$λ$ = 250-2500 $μ$ m。
We present here a small-scale liquid Helium (LHe) immersion cryostat with an innovative optical setup suitable to work in long wavelength radiation ranges and under applied magnetic field. The cryostat is a multi stage device with several shielding in addition to several optical stages. The system has been designed with an external liquid Nitrogen boiler to reduce the liquid bubbling. The optical and mechanical properties of the optical elements were calculated and optimized for the designed configuration while the optical layout has been simulated and optimized among different configurations based on the geometry of the device. The final design has been optimized for low noise radiation measurements of proximity junction arrays under applied magnetic field in the wavelength range $λ$=250-2500 $μ$m.
