Superconducting Neutron Detectors

Abstract

The superconductivity has been applied to detect a neutron through sequential detector development. The current-biased transition-edge detector (CB-TED) of MgB₂ wire detected neutrons successfully at temperatures near the critical temperature. Contrarily, the Nb-based current-biased kinetic inductance detector (CB-KID) with a ¹⁰B converter observed neutrons at wide temperatures in the superconducting state. Finally, the delay-line CB-KID achieved neutron imaging by using only the four leads from the detector.
