Times Cited Count：114 Percentile：95.27(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.

AMATERAS is a cold-neutron disk-chopper spectrometer newly installed at MLF, J-PARC. The spectrometer has pulse shaping chopper which can cat the source pulse shape as it is required by the experiments. By using newly developed high-speed disk-choppers, the spectrometer realizes both high energy resolution and high intensity with high flexibility in the cold and thermal neutron energy region. The construction of the spectrometer has been completed in spring of 2009. After the commissioning works, now the spectrometer is open to users. In this presentation, we will show the evaluated performances which were obtained in commissioning works.

AMATERAS is a cold-neutron disk-chopper spectrometer newly constructed in Materials and Life science Facility in J-PARC. Construction of the spectrometer has been completed in this spring and on 27 May, 2009 AMATERAS opened its shutter for the first neutron beam. AMATERAS is now in commissioning phase and will be ready for user program from this December. In this presentation, detail of the spectrometer, results from commissioning and plan of user program will be shown.

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.

AMATERAS is a cold-neutron disk-chopper spectrometer installed at beam-line No. 14 at Materials and Life Science Experimental Facility (MLF) at J-PARC. Owing to the use of newly developed high-speed disk choppers and the high peak intensity from the coupled moderator source of MLF, the AMATERAS design to realize high-intensity and fine and flexible energy resolution measurements in quasielastic and inelastic neutron scattering experiments in cold and sub-thermal neutron energy region. In this presentation, we will show the current status of AMATEAS including the results of performance tests and some of examples of scientific outputs.

AMATERAS is a disk-chopper-type spectrometer installed at beam-line No. 14 at Materials and Life Science Experimental Facility (MLF) of J-PARC. AMATERAS is equipped with an extra chopper for pulse shaping at the upstream position, in addition to a monochromating chopper. Owing to the use of these choppers and the high peak intensity from a coupled moderator source at MLF, AMATERAS is designed to realize high-intensity and fine and flexible energy resolution measurements in quasielastic and inelastic neutron scattering experiments in cold and sub-thermal neutron energy region. The spectrometer had the first neutron beam in May 2009 and user program started from December, 2009. During the course of commissioning and users' experiments, the performance of the spectrometer was confirmed by conducting test experiments. In this presentation, we will show the current status of AMATEAS including the results of performance tests and some of examples of scientific outputs.
