BACKGROUND

Selecting one method for ionizing particle radiation detectionversus one another, depends on the cost/detection ratio accuracy level, required by the application. The readout chain must ensure sufficiently high resolution to characterize a narrow pulse with a time width of few nanoseconds. Most of the existing semiconductor particle detectors are based on a direct reading of the detected currents shapes, which is very costly as it requires high quality amplifiers.

HOW IT WORKS

Our particles detector offers a new approach with indirect detection of the current generated at the input of the readout chain.

Particle is easily characterized by :

• the peak width achieved by reading the frequency variation curve,

• the peak amplitude, measured by the average oscillation voltage.
