Rita Star

Rita Star is a thin layer linear analyzer specially designed for beta detection. The detector has an active length of 200 mm. For various applications the active width can be limited from 20 mm down to 15, 10, 3 and 1 mm by simple exchange of the diaphragm. All ionizing radiation is detectable by the Rita Star position sensitive proportional gas flow counter.
For the measurement of the low energy betas of tritium the counting tube has to be used without any window and as close as possible to the radiation source. Therefore the Rita Star detector rests on the surface of the sample in order to close the counting chamber, to reduce gas leakage and to present a zero distance between source and detector.


Detector

The gold plated detector Rita Star is the only detector for position sensitive proportional counting, which uses a gold plated sensing element.
