Analog tests of the new ISPA-tube readout system

A new readout system for hybrid photon detectors is being developed by the collaboration and has been operated for the first time to test the analog front-end. In order to test its performance we used the ISPA (Imaging Silicon Pixel Array)-tube, a position sensitive photon detector based on the hybrid technology which contains a pixel detector array with 2048 pixels of 50times500 mum² pitch. In this paper, we present the first successful application of this gamma camera prototype with a compact and portable readout system based on new electronics, able to provide full control and real-time data processing and analysis.
