最近对旋转超流He和He的研究导致建造了巨大的旋转冰箱。我们已经建立了，另一方面，一个紧凑，廉价和易于操作的旋转低温搜索新的超流现象。我们的新型旋转低温恒温器非常简单，一个操作员就可以操作并进行连续测量。低温恒温器和电子设备作为一个整体通过直接连接在下面的旋转器旋转。最大旋转角速度为6.28 rad/s，这是现有旋转低温恒温器的中间值。在旋转过程中的性能进行了讨论。
Recent studies of rotating superfluidHe andHe had led to construct massive rotating refrigerators. We have built, on the other hand, a compact, inexpensive and easily operated rotating cryostat for search for novel superfluid phenomena. Our new rotating cryostat is so simple that one operator can handle it and make continuous measurements. The cryostat and electronic devices are rotated as a whole by a servomotor directly attached underneath. The maximal rotation angular velocity is 6.28 rad/s, which is an intermediate value in existing rotating cryostats. The performance during rotation is discussed.
