A study has been made which demonstrates the feasibility of developing a nuclear particle detector utilizing tunneling between superconductors.
For optimum detector performance, temperatures lower than 1.2°K are mandatory. Accordingly, a He⁴ cryostat capable of being modified to a He³ cryostat has been constructed and tested.
The detectors, which have been fabricated and tested at 1.4° K, consist of thin aluminum and lead films separated by an insulating layer of aluminum oxide. The d-c tunneling currents have been observed and are found to compare favourably with the results of previous workers.
The d-c response of the device to gamma radiation was, as expected, unobservable. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
