METHOD AND DEVICE FOR RECORDING CHARGED PARTICLES Russian patent published in 2007 - IPC G01T5/08 

FIELD: prospecting of uranium, thorium and other mineral resource deposits, seismology, ecology, radiation dosimetry, radio-biological and space research, gas logging of wells, etc.

SUBSTANCE: suggested method for recording charged particles includes using solid track detectors, while solid track detectors are made using a set of optical fibers without protective covers in place of recording of charged particles, while registration of charged particle tracks is performed by means of double exposition holographic photo-resilience through the ends of optical fibers, by letting polarized light through them. Presence of charged particle tracks may be recorded based on change of transparency of each separate optical fiber, while transparence change evaluation is performed by means of polarization analyzer, mounted on opposite ends of given optical fiber, and a device for recording intensiveness of light passing through the fiber. Aforementioned method is realized by an appropriate device for recording charged particles.

EFFECT: no need for chemical etching, lower laboriousness of tests, possible multiple usage of optical fibers without changing their position.
