Method of fast broadband radiation detection from pulse sources and fast broadband radiation detector

摘要

The fast broadband radiation detector operates on the basis of ultra-rapid demagnetization and subsequent thermomagnetic effect, using a sensor element (1) consisting of a ferromagnetic or antiferromagnetic material in the form of a nano / micro-layer or nano / microstructure or a macroscopic structure in the case of metal ferromagnetic material, in which the magnitude or direction of the magnetic moment of the ferromagnetic material changes due to the directly impact of the radiation or indirectly due to the influence of the hot electrons, registered by the detection unit (2). The detection unit (2) comprises at least one passive element - a magnetic antenna based on a single-screw coil, coplanar wiring, or other inductance element and / or active element - a magnetoresistant sensor for detecting a rapid change in the magnetic moment of the ferromagnetic or antiferromagnetic material.
