Abstract

Controlled-drift detectors are fully-depleted Si detectors for X-ray imaging which combine good position resolution with a very fast frame readout. The basic feature of the controlled-drift detector is the transport of the charge packets stored in each pixel column to the output electrode by means of a uniform drift field. The drift time of the charge packet identifies the pixel of incidence. Images of an X-ray source obtained with the controlled-drift detector up to 100 kHz frame rate are presented and discussed. The achievable energy resolution as a function of the operating temperature and frame rate is analyzed
