Anashin V. S. Sensors for on-board dose metering systems


The paper discusses the development problems of a cumulative dose sensor (CDS) which is a key element of the on-board segment of monitoring systems for space ionizing radiation. It justifies the choice of sensing element based on MIS dosimetry operation principle. Engineering requirements to on-board dose metering devices and to CDS design concepts and structure development are formulated. Priority areas in the field of on-board dose metering are specified.

Keywords: space ionizing radiation, monitoring system, on-board segment, cumulative dose sensors, sensing element.
