Development of a data acquisition sub-system using DAQ-Middleware

Abstract

A prototype of a data acquisition (DAQ) sub-system has been developed at the Material and Life Science Facility (MLF), the Japan Proton Accelerator Research Complex (J-PARC). This prototype was built using software components called DAQ-Components in DAQ-Middleware. The DAQ sub-system attained scalability and flexibility, resulting from the nature of the DAQ-Components, their location transparency. The DAQ sub-system can be easily extended to keep in step with the increase in the beam intensity of J-PARC. Results of beam tests using the DAQ-Components in September 2007 certified the required fundamental DAQ functions of DAQ-Middleware.
