Period

SEPT.-OCT.1997

Canada

CANADIAN DEVELOPED & MANUFACTURED RADIATION DETECTORS, WHICH FLEW ON U.S. SPACE SHUTTLE MISSION STS-86 OF SEPT. 25 TO OCT. 5 1997, TO MIR SPACE STATION. DETECTORS SERVED AS SENSORS IN CREAM (COSMIC RADIATION EFFECTS & ACTIVATION MONITOR) EXPERIMENTS CARRIED OUT ON MIR DURING THAT MISSION.

Function

DEVICE USED TO MEASURE NEUTRON RADIATION. DETECTOR CONSISTS OF TINY DROPLETS OF SUPERHEATED LIQUID DISPERSED THROUGH ELASTIC POLYMER. WHEN DROPLETS ARE STRUCK BY NEUTRONS, THEY FORM SMALL GAS BUBBLES THAT REMAIN FIXED IN POLYMER TO PROVIDE REAL TIME VISUAL RECORD, WITH NUMBER OF BUBBLES INDICATING RADIATION LEVELS. THESE DETECTORS FORMED SPECTROMETER PACKAGE & WERE USED ON SPACE STATION TO MONITOR NEUTRON LEVELS.

Technical

THIS GROUP OF SIX BUBBLE RADIATION DETECTORS FORMS PART OF COMPLETE SPECTROMETER PACKAGE CONSISTING OF 36 DETECTORS, WITH SIX DIFFERENT ENERGY THRESHOLDS. THIS RANGE MAKES THEM PARTICULARLY USEFUL IN MEASUREMENT OF NUCLEAR SPECTRUM IN SPACE, WHERE THEIR INSENSITIVITY TO OTHER CHARGED PARTICLES IS ALSO MAJOR ADVANTAGE.
