Dilution and adiabatic demagnetization refrigerators based on pulse tube cryocoolers are nowadays used in many low temperature physics experiments, such as atomic force and scanning tunneling microscopy, quantum computing, radiation detectors, and many others. A pulse tube refrigerator greatly simplifies the laboratory activities being a cryogen-free system. The major disadvantage of a pulse tube cooler is the high level of mechanical vibrations at the warm and cold interfaces that could substantially affect the performance of very sensitive cryogenic instruments. In this paper, we describe the performance of a very simple mechanical attenuation system used to eliminate the pulse-tube-induced low frequency noise of the superconducting transition-edge sensors under development for the instruments of the next generation of infra-red and X-ray space observatories.
基于脉管制冷机的稀释制冷机和绝热去磁制冷机如今被用于许多低温物理实验中，比如原子力显微镜和扫描隧道显微镜、量子计算、辐射探测器等等。脉管制冷机作为一种无低温制冷剂的系统，极大地简化了实验室操作。脉管制冷机的主要缺点是在冷热界面处存在高水平的机械振动，这可能会严重影响非常灵敏的低温仪器的性能。在本文中，我们描述了一种非常简单的机械衰减系统的性能，该系统用于消除正在为下一代红外和X射线空间天文台的仪器研发的超导转变边缘传感器中由脉管引起的低频噪声。
