Compatibility with Exogam system

An electronics system for Exogam is being built to process energy and timing information, make trigger decisions and relay data onto an acquisition system. The electronics will be based on the VXI and VME electronics systems in which the UK has considerable expertise. Purpose built VXI cards for the new detectors are being designed and built in the UK and France. The TIARA electronics and data acquisition will need to be compatible with the Exogam system in order to best exploit the potential benefits. During the design stage of Exogam, the TIARA team maintained close links with Exogam and was represented at the electronics and data acquisition planning meetings. The best matching of the systems, based on this information, is for TIARA to have independent signal amplification and trigger definition electronics and then to feed in to the Exogam data acquisition at the digital conversion stage.
