The Coincidence / Logic / Trigger Units family provides flexible tools for building trigger and logic architectures in nuclear and particle physics experiments. These modules enable the implementation of coincidence, majority, AND/OR logic, fan-in/fan-out distribution, and signal translation functions while maintaining precise timing and low propagation delay.
Designed for both fixed-function and programmable use cases, the family includes compact NIM and VME modules as well as fully configurable FPGA-based platforms. They allow users to combine and process detector signals, generate triggers, and implement complex logic chains with support for multiple logic standards and configurable output widths. With modular architectures and scalable channel counts, these units can be used from simple coincidence setups to advanced multi-detector trigger systems.
