Times Cited Count：27 Percentile：85.04(Instruments & Instrumentation)A new beamline for a fundamental physics experiment is under construction at BL05 port in the Materials and Life Science Facility (MLF) at Japan Proton Accelerator Research Complex (J-PARC), this beamline is designed using novel techniques of neutron optics and it is termed "Neutron Optics and Physics". The beam from the moderator is deflected by multi-channel supermirrors and split into three branches for individual experiments. In this study, we have optimized the design of the beam optics and shields using the Monte Carlo simulation package PHITS. The neutron fluxes of beams are expected to be

One of the experimental facilities in Japan Proton Accelerator Research Complex (J-PARC) is the Materials and Life Science Experimental Facility (MLF), where high-intensity neutron beams and muon beams are used as powerful probes for materials science, life science and related engineering. The neutrons and muons are generated with high-intensity proton beam from 3-GeV rapid cycling synchrotron (RCS). The high-intensity proton beam has to be effectively transported, and a neutron production target and a muon production target have to be also properly irradiated. The principal design of the 3-GeV proton beam transport facility (3NBT) is systematized.

We have started the commissioning of the neutron scattering experiment instruments since May 2008 in MLF, J-PARC. Simultaneously, we have started the commissioning of the data acquisition and analysis software. Experimental users operate this software through the software framework which we have developed. The software framework was developed based on Python which is an object oriented script language. The system implemented with the software framework can seamlessly measure, analyze and visualize with some modules which are experimental control and data analysis. In this presentation, we report the process of the construction and the current status of the software.

We have developed the software framework in MLF computing environment from 2006 to 2008. The software framework is the fundamental software for neutron and muon experimental instruments in J-PARC/MLF. Currently, the software framework is installed at 4D Space Access Neutron Spectrometer (BL01), IBARAKI Biological Crystal Diffractometer (BL03), Cold-Neutron Disk-Chopper Spectrometer (BL14), Engineering Materials Diffractometer (BL19) and High Intensity Total Diffractometer (BL21). The features of experimental control, analysis, visualization and authorization are already implemented in the software framework. In this year, we will start the development to introduce the feature of database. We will present the current status and future plan of the software framework.

The first neutron was produced on May 2008, the first muon was extracted on September 2008 and the operation for the first user program started on December 2008 in J-PARC/MLF. The beam power of proton are increasing from 4.3kW to 120kW, the number of the experimental instruments are increasing from 8 to 14. In addition, the constructions of new instruments were started in this year. Many users started the experiments in each instruments and measured the data. Under these situations, the requirements of the MLF computing environment are increased more and more. In this year, we provided the project management server, the trial distributed data processing system, the sample management system with database and Gigabit Ethernet backbone.

In this year, we are developing the following three items in the software framework "IROHA" which is the standard software for J-PARC/MLF computing environment. First, the experimental metadata are managed by the MLF database, which is available for the multi-dimensional data analysis environment. Second, the automatic experimental software is called "Experiment Scheduler", which is collaborated with ISIS. And third, the digital and analog signals are acquired as general event with "TRIGNET" which is the event recording system for the variation of the external fields. We present the detail of these items and the remote data analysis environment which we will introduce next year.
