Beginner's course; Computing environment in MLF

Nakatani, Takeshi ; Inamura, Yasuhiro  

In the Materials and Life science experimental Facility (MLF) of J-PARC, the computing environment group was organized from the construction of MLF. The group has been developed and operated the neutron event-recording data acquisition (DAQ) system, the data analysis library and the device control software framework for neutron experimental instruments in MLF. In this article, we report the new developments as follows: The universal event-recording DAQ system to make the most of the intense neutrons; the data process framework to enable multi-dimensional data analysis at various neutron instruments; the remote access to be easily able to monitor a measurement status and handle many kinds of enormous data from anytime, anywhere.
