Note on the equalization of the temperatures of interferometer tubes
John Job Manley · Proceedings of the Physical Society · 1934
This note is a description of two devices used for establishing and maintaining equality and uniformity of temperature for the contents of the twin tubes of Jamin interferometers. According to one method the tubes are closely wound from end to end with spirals of soft copper wire, s.w.g. 18. The other device consists of an aluminium chamber which during idle periods completely encloses the tubes. Shutters, covering the ends of the tubes, are removed prior to the carrying out of measurements.
