ESA Radiation Monitoring and Component Technology Test-Bed Instruments 

Standard Radiation Environment Monitor

SREM (Contraves Space, Switzerland)

A decision was made by the ESA management board to develop and fly a Standard Radiation Environment Monitor on future ESA projects with the following objectives:

• To aid satellite performance, anomaly and failure investigations.
• With preloaded radiation thresholds to act as a warning / alarm system for the spacecraft.
• To assist in the improvement of design of future spacecraft
• To allow the creation and maintenance of a European radiation database.

Real-time RadFET Dosimeter

RRD1 RRD2 (NMRC, Ireland)

The RadFET is basically a MOS structure where a change in the electrical properties of the device due to charge generation and trapping in the MOS gate insulator is used to measure the total ionising dose received. The RadFET may be used for local real-time dosimetry at critical points of a spacecraft. The development of a real-time RadFET reader for flight on the BIOPAN (ESA experiment) has been initiated.
