SUPERCONDUCTIVE IMAGE DETECTOR

摘要

PROBLEM TO BE SOLVED: To uniformize detection sensitivity of a superconductive tunnel junction(STJ) to improve both enhancement of detection performance and a stable operation, and to provide image detection of high performance. SOLUTION: A phonon, a quasiparticle or the like is generated by making a radiation incident into a substrate. An incident position and energy of the radiation are measured based on a propagation time difference and energy detected by plural STJs integrated in a periphery of the substrate. Micro strip coils different each other are integrated in the respective STJs to be coupled electromagnetically onto the respective STJs, and a current flowing in the each micro strip coil is regulated to unify the detection sensitivity of the each STJ in an induced magnetic field. Since a Josephson current is restrained thereby to get uniform, a dispersion on manufacturing an element such as a characteristic in the STJ and an incident angle of an external magnetic field is regulated individually.
