Enhancing Hadron Calorimeter and GEM Tracker Readout Performance with Fastbus and ADC Technology

This project focuses on upgrading hadron calorimeter and GEM tracker readout systems. Utilizing Fastbus technology with pipeline Flash ADCs, advancements include reduced deadtime, improved triggering algorithms, and increased data processing efficiency. Testing over 6200 ADC channels, the implementation integrates analog and digital triggers for optimal performance. This innovative setup also enables Linux VME controller compatibility and integration with JLAB's DAQ environment.
