Times Cited Count：143 Percentile：95.98(Physics, Multidisciplinary)AMATERAS is a cold-neutron disk-chopper spectrometer in MLF, J-PARC. The construction of main part of the spectrometer has been completed in spring of 2009. Soon after that, we have started the commissioning work on AMATERAS. The performance of AMATERAS has been examined by test experiments in the course of commissioning. In parallel to these works, we have started the user program on AMATERAS from December 2009 and we are getting scientific results from our spectrometer. In this presentation, we will report the current status of AMATERAS including the results of performance tests and some of examples of scientific outputs.

Times Cited Count：6 Percentile：39.64(Nuclear Science & Technology)In the JT-60 tokamak at JAERI, environment for remote participation is planned to be developed by concentrating experts of nuclear fusion research of another research organizations and universities distributed all over the country. We are constructing a hierarchical remote research system, which consists of remote experiment, remote analysis, and remote diagnostic. In a remote collaboration, it is important to maintain the security of the system, as well as to share the information, atmosphere and presence between the participants. For the latter purpose, we developed a video conferencing system, and a video streaming system that can deliver the images of the JT-60 control room. Furthermore, a development of the remote analysis system called "VizAnalysis" has been started. And to assist the remote analysis, we developed a web based software system called "VizSquare". In the JT-60 tokamak at JAERI, security and authentication methods on a computer network and a new communication tool are developed, and probably they will be applied to the remote participation of ITER.

To establish sealing technique suitable for geological environmental conditions of Japan, it is necessary to obtain data related with this sealing function through laboratory tests and in-situ tests. It also is necessary to put these data to practical use and to establish the estimating method of the sealing technique. This report deals with the sealing function tests under heating condition of supplying water, following the pressurized tests of supplying water at the AECL in Canada until last year. These test results are reported here together with the data, interpretation and analysis of tracer test results. Information arrangement for the establishment of estimation method of sealing function is also performed.

AMATERAS is a cold-neutron disk-chopper spectrometer in Materials and Life science Facility in J-PARC. By combination of high-peak intensity from a H
-coupled moderator source and newly developed high-speed disk-choppers (the maximum revolution: 350Hz, the minimum burst time: 7.6 
sec.) for pulse shaping and monochromating, the spectrometer realizes both high-resolution (
) and high-intensity (one order of magnitude higher than the present state-of-the-art chopper spectrometers) in the range of 
meV, and can show sufficient performance up to 
80 meV. Construction of AMTERAS has been completed in March 2009 and the spectrometer is at commissioning phase. In this presentation, we will report the current status of AMATERAS including the first results obtained at commissioning.

A Si-crystal analyzer backscattering spectrometer DNA is planned to be installed at the pulsed neutron source of the Material and Life Science Facility (MLF), J-PARC, and the construction has partially begun in the summer of 2010. The field of expected scientific research on the DNA spectrometer is very wide including the soft matter dynamics, the bio-molecular dynamics, the chemical molecular dynamics, the characterizations of the functional materials and the spin dynamics in the magnetism.
