Control and monitoring of data acquisition and trigger system (TRIDAQ) for backing calorimeter (BAC) of the ZEUS experiment

The paper presents ideas and realization of hardware (photonics and electronics) and software diagnostic layers of TRIDAQ for BAC calorimeter of ZEUS experiment at HERA accelerator. The aim of diagnostic system (DS) is to provide high reliability of the BAC. The diagnostic system localizes, in the fastest possible way, place, time and cause of any breakdown inside the BAC. Functionalities of diagnostic system were discussed. Construction of distributed, diagnostic hardware layer was presented. The software layer of the system was designed using the object-oriented approach. Object oriented virtual classes were defined. These classes control electronics and photonics devices and sub-systems. Application examples were presented. The implementation results of DS for TRIDAQ were discussed.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
