Abstract
A method and apparatus for automated read-out of a superheated droplet-to-bubble type detector whereby a light source is positioned near one end of a droplet-containing medium which is protected from undesired light. A light sensor is positioned to detect changes in light that has traversed the medium from the light source. The sensor provides a read-out signal of changes in light intensity due to radiation and the read-out signal is monitored. Optionally, the light source intensity is monitored to correct the read-out signal for fluctuations in the light source intensity.
Claims11
A method for automated read-out of a radiation detector of the superheated droplet-to-bubble type, comprising:
- a) positioning a selected light source in proximity to one end of the droplet-containing medium so that light from the source will traverse the medium;
- b) protecting the medium from undesired light;
- c) positioning a selected light sensor so as to detect only changes in light that have traversed the medium from said source, the sensor being selected to provide a read-out signal of changes in light intensity due to radiation;
- and
- d) passing said read-out signal to appropriate monitoring means.
An automated radiation detector of the superheated droplet-to-bubble type, comprising:
- i) detector means including a selected medium having dispersed droplets adapted to be superheated when in use;
- ii) a selected light source in proximity to one end of said medium and adapted to pass light through said medium;
- iii) means to protect the medium from undesired light;
- and
- iv) a selected light sensor positioned to detect changes in light passing through the medium from the light source, the sensor being selected to provide a read-out signal of said changes in light passing through the medium.
