Abstract

Recent studies of rotating superfluid (Formula presented.)He and (Formula presented.)He 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.
