Superconducting MgB2 Thin Film Detector for Neutrons

The superconducting neutron detector using high-quality 10 B-enriched MgB 2 thin films at higher operating temperatures has been proposed, where a resistance change induced by the nuclear reaction of neutron and 10 B in MgB 2 is used to detect a neutron. Cold neutrons from a nuclear research reactor...

Zusammenfassung:	The superconducting neutron detector using high-quality 10 B-enriched MgB 2 thin films at higher operating temperatures has been proposed, where a resistance change induced by the nuclear reaction of neutron and 10 B in MgB 2 is used to detect a neutron. Cold neutrons from a nuclear research reactor irradiated the MgB 2 detector, and the output voltage was clearly observed through a low-noise amplifier by using a digital oscilloscope. The out-of-equilibrium thermodynamics was investigated by means of the time-dependent Ginzburg-Landau equations by using the Earth Simulator.
