Implemented local data processing before data storage.

Abstract

This paper describes the data acquisition and trigger system of the Thin Time-of-flight PET (TT-PET) scanner. The system is designed to read out in the order of 1000 pixel sensors used in the scanner and to provide a reference timing signal to each sensor in order to measure time differences of better than 30 ps. This clock distribution is measured to have a jitter of less than 4 ps at the sensors. Collected data is locally processed before being forwarded to storage. Data flow as well as control, configuration and monitoring aspects are are also addressed.
