Özet

Silicon drift detectors (SDD) are state of the art devices for spectroscopy applications. The utmost energy resolution can be obtained by means of low noise front-end electronics, having shaping time of the order of microseconds. We are proposing a new front-end electronics for applications that may benefit from higher rate capability while maintaining a reasonable spectroscopic resolution. The idea is to combine a high speed semi-Gaussian shaping amplifier (originally designed for gas detectors) with very compact high speed low noise input-output stages. The shaper amplifier is implemented in hybrid technology. The shaping time can be controlled from 5ns to 50ns.
