Abstract
A radioactive ray detecting device comprises a superconductor element formed without an underlying substrate, an oxide film formed on a surface of the superconductor element, and a superconductor thin film formed on the oxide film. The oxide film and the superconductor thin film cover substantially an entire periphery of the surface of the superconductor element. The semiconductor element may be formed of a polycrystalline material such as aluminum, or a single crystal superconductor such as one containing tin, lead, niobium or tantalum, and may have a circular cross section or a rectangular cross section.

A radioactive ray detecting device comprising:
- a columnar superconductor;
- an oxide film formed on a surface of the columnar superconductor;
- and a superconductor thin film provided on the oxide film;
- wherein the oxide film and the superconductor thin film cover substantially an entire periphery of this surface of the columnar superconductor.
A radioactive ray detecting device fabricating process comprising the steps of:
- forming a first superconductor thin film on a side surface of a columnar superconductors oxidizing the first superconductor thin film to form an oxide film;
- and thereafter providing a second superconductor thin film;
- wherein the first superconductor thin film and the oxide film and the second superconductor thin film cover substantially an entire periphery of a surface of the columnar superconductor.
