RHIC beam synchronous trigger module

Abstract

The RHIC Beam Synchronous Event System consists of centralized event encoders (one for each collider ring), which operate from the RF clock and the revolution clock provided by the RHIC RF system, and distributed embedded decoders. The Beam Synchronous Trigger Module (V124) is a general purpose 6U/spl times/4HP, VMEbus controlled module that is compatible with the RHIC Beam Synchronous Event System and is designed to provide clocks and triggers for collider data acquisition systems and experiments. The V124 Module contains a separate memory (Bunch Fill Mask RAM) for each channel that is software configurable with the pattern of filled buckets (Bunch Fill Pattern) to permit bunch synchronous triggering/clocking. This module provides eight identical channels that can be configured independently or in pairs, and a buffered RF clock output.
