Abstract

We introduce a new readout system for flat panel PSPMT detectors, based on discrete semiconductors. Due to the high number of simultaneous channels to be acquired, the first and most important component selected is the 8 channel ADC with 8 different track and hold. This approach enables us to acquire each of the requested 64 anodic channels in parallel, at 250 ksps/ch, with a typical resolution of 14 bits. All the necessary 8 ADCs are controlled by an FPGA, and an embedded Linux based CPU, that made the system capable to transfer data trough the Ethernet port or store it in an USB mass storage device like the popular USB pen.
