The aim of this work is the characterization of the Pixirad-1 detector system with monochromatic synchrotron radiation at different energies. The linearity of the system has been investigated varying the impinging photon flux up to paralyzation. The ratio between detector counts and number of impinging photons, as a function of energy and discriminator thresholds, has been measured. The pixel noise has been evaluated and the result compared with the theoretical Poisson model.

Abstract

The aim of this work is the characterization of the Pixirad-1 detector system with monochromatic synchrotron radiation at different energies. The linearity of the system has been investigated varying the impinging photon flux up to paralyzation. The ratio between detector counts and number of impinging photons, as a function of energy and discriminator thresholds, has been measured. The pixel noise has been evaluated and the result compared with the theoretical Poisson model. Eventually, the spatial resolution has been evaluated by measuring the line-spread function at different energies and discriminator thresholds.
