Study and setting up of a time varying filter
Description
The use of a time varying filter in a gamma spectrometry System permits to obtain a good B/S ratio at high counting rate. This filter includes a CR differentiator circuit, a gradually opening linear gate and a fast reset integrator. This work presents the theoretical study of the B/S ratio for different values of the parameters, the circuits hardware and the measurement. (author)
Abstract (French)
L'utilisation d'un filtre a parametres variables dans le temps dans un ensemble de spectrometrie gamma permet d'augmenter le taux de comptage sans trop degrader le rapport bruit a signal. Ce filtre comprend un circuit de derivation CR, une porte lineaire a ouverture graduelle ainsi qu'un integrateur actif a remise a zero rapide. Le travail presente ici rend compte de l'etude theorique du rapport bruit a signal du filtre en fonction des differents parametres, de la conception des circuits, et de l'experimentation.
