Description
Summary:The hybrid pixelated semiconductor Timepix detector is the successor of the Medipix2 X-ray detector. It is provided with additional functions directly integrated in the pixel electronics which allows to perform the measurement of event times of interacting X-ray photons in the silicon sensor layer in respect of the end of each acquisition. Due to the number of pixels of the device there are 65536 independently working channels available to determine the time structure of high flux X-ray sources which are operating in a pulsed mode. These X-ray sources are commonly used in medical applications and homeland security and create X-ray bursts in the range of 50 ns. We present the results of the time resolved measurement of a pulsed X-ray field and the corresponding measurement which was done in a collaboration with the Physikalisch Technische Bundesanstalt (PTB).
