An original instrumentation technique is to be proposed for nuclear detection, based on the photobleaching effect in optical fibres. The technical proposal will be accompanied by an assessment of the market for the proposed device.
The photobleaching effect will be measured with two types of fibres:
- fibres with silica cores
- special fibres containing boron impurities.
With each fibre type the propagation characteristics will be determined in the presence of radiation and photobleaching will be measured using an alternative technique. As the frequency, intensity and wavelength of the photobleaching signal must be varied, a substantial volume of measurements will be needed.
A restricted market survey will be conducted on the size, variety and cost of conventional radiation detectors and counters. This survey will be done in the nuclear power plant, industrial and hospital environments.
