Preliminary results of the experimental and simulated intrinsic properties of the Compteur A Trou (CAT) detector: behavior with synchrotron radiation

This paper describes a wireless proportional gas detector using a new type of intrinsic electric field shape for electronic amplification cascade. Its properties are analyzed by means of numerical simulations compared with experimental measurements. Electronic gain, energy resolution and count rate are established for pure argon gas and a mixture of argon and CO2. Measurements with a synchrotron light source show that CAT can achieve count rates as high as 107 mm2 S.
