Abstract

<p>The first neutron was produced on May 2008 in Japan Proton Accelerator Research Complex (J-PARC) / Materials and Life science experimental Facility (MLF). The MLF computing environment group is developing an advanced data acquisition and analysis environments for neutron experiments according to a long-range objective. We have introduced the standard data acquisition system which records the neutron signal from detectors with event by event. This event data recording system acquires neutron detection data with the “DAQ-Middleware” which is the flexible and scalable data acquisition software. The standard data analysis framework, “Manyo-Lib”, is written in C++ and class library. Manyo-Lib is a software infrastructure and provides the libraries for building data input/output functions, data-analysis functions, and distributed data processing, etc. MLF users can operate the experimental instrument through MLF software framework called “IROHA” which unifies these software components.</p>
