Particle Identification and Tracking by the Use of a Pixel-Based Semiconductor Radiation Detector Coupled with Voltage Controlled Oscillators

Abstract

A particle detection chain based on a CMOS SOI VCO circuit associated to a matrix of detection is presented. The solution is optimized for the recognition and tracking of various particles. Two ions are considered: an alpha and an aluminum. These two ions were chosen because there are very different in terms of energy and LET variations.

Particles discrimination and tracking through a matrix of detection coupled with a voltage-controlled oscillator

“…In this context, an approach based on the use of a ring oscillator was developed with an innovative conditioning method [10][11][12][13][14][15][16][17]. This approach is based on the reading of the information related to indirect output parameters of the detection chain signal (i.e.…”
