Abstract

The sensitivity of some analog and digital integrated circuits (ICs) to ionizing radiation was tested in order to evaluate their potential usefulness especially in the PROMICS-3 instrument. The PROMICS-3 is a plasma instrument to be flown on the Russian Interball satellites. The radiation tolerance requirement of the auroral Interball satellite is about 45 head/year inside a shielding of 4 mm Aluminium The IC's tested ware: AD571 A/D-converter, ADDAC80 D/A-converter, LF442A and PM108A operational amplifiers, MPREF01 voltage reference, STC SPXO 6 MHZ oscillator, 4N55 optocoupler, MC51C98 and CY7C164 16k*4 static CMOS RAM. Co60 was used as the irradiation source. The test methods and results are described in this paper. The RAM-circuits failed between 10 and 20 head. D/A- and A/D-converters degraded only slightly after 100 head, but one of the A/D-converters failed functionally at lg0 head. The LF442A began to degrade in the test connection at 100 head, and PM108A at 30 head. The output voltage of the voltage reference MPREF01 increased about 20 mV after 100 kind. No change was observed in the output frequency of the STC SPXD oscillator even after 300 head. The current transfer ratio of the 4N55 decreased continuously to about 75 % of the initial value after 100 head. This report describes the realisation of a prototype optical proximity sensor aimed to help the control of an underwater manipulator. The construction of the prototype sensor with its control software and the test environment are presented. Some preliminary test results are shown.
