Times Cited Count：139 Percentile：95.91(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 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.

Low Active Waste Treatment Development Facility (LWTF) is planning to solidify the cement waste liquid generated at the Tokai Reprocessing Facility. In the previous report, it has been shown that the carbonate waste liquid can be solidified by conducting a solidification test on the waste liquid simulating the carbonate waste liquid containing sodium carbonate and sodium nitrate. On the other hand, it is expected that sodium sulfate will coexist as a foreign substances in the carbonate waste liquid, even though it is a trace amount, and it has been confirmed that there is no effect of sodium sulfate coexists in beaker-scale test. In this report, a actual-scale test is carried out, confirm that there is no effect when sodium sulfate coexists, and the results is reported. It was confirmed that the presence or absence of sodium sulfate in the waste liquid had no effect on the fluidity of the sample after kneading, the compressive strength of the sample after curing, etc., and thus had no effect on the solidified body properties.

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.
