我们展示了使用基于正常金属/绝缘体/超导体（NIS）隧道结的固态制冷器对X射线转变边缘传感器（TES）进行冷却。我们能够在260毫开的起始温度下操作NIS制冷器，该温度比TES转变温度（185毫开）高75毫开，并且仍然能够获得高质量的X射线光谱，在5.9keV处半高宽的能量分辨率为9.5±0.3电子伏特。NIS制冷器实现的最大冷却为110毫开，从300毫开的起始温度降至190毫开。
We demonstrate cooling of an x-ray transition-edge sensor (TES) using solid-state refrigerators based on normal-metal/insulator/superconductor (NIS) tunnel junctions. We are able to operate the NIS refrigerators at a starting temperature of 260mK, which is 75mK above the TES transition temperature (185mK), and still achieve high quality x-ray spectra with an energy resolution of 9.5±0.3eV full width at half maximum at 5.9keV. The maximum cooling achieved by the NIS refrigerators is 110mK, from a starting temperature of 300 down to 190mK.
