摘要:Membrane proteins are major players in important cell processes and, therefore, are key targets for research on human health and drug development. The crystals of these membrane proteins typically have large unit cells with repeat of a few hundred angstroms. The average inte...

摘要:New high-flux and high-brilliance neutron sources demand a higher count-rate capability in neutron detectors. In order to achieve that goal, the Solid-State Neutron Detector (SoNDe) project is developing a scintillation-based neutron detector. It will be capable of fully exploiti...

摘要:The existence of permanent neutron electric dipole moment (nEDM) violates the time reversal symmetry, therefore this is good probe for search CP violation from new physics beyond the standard model of particle physics (assuming CPT = 1). The present upper limit was measured ...

摘要:The neutron is suitable for precision measurements to search for new physics. Combination of the pulsed neutrons provided by J-PARC and the advanced optical devices enables us to perform new types of high precision measurements. The large CP violation should exist to explain the ...

摘要:Highly oriented pyrolytic graphite (HOPG) monochromators with low mosaic (grades PGCX04, PGCX05, ZYA, AGraphY, etc.) are only available up to a maximum size of 50 × 50 mm2. In particular for one-dimensional focusing, several monochromators have to be glued or scre...

摘要:Ultracold neutrons (UCN) with kinetic energies up to 300 neV can be stored in material or magnetic confinements for hundreds of seconds. This makes them a very useful tool for probing fundamental symmetries of nature, by searching for charge-parity violation by a neutron electric...

摘要:Pulsed polarized neutron imaging is considered to be a promising method for direct observation of magnetic fields in industrial products under operating conditions. To quantitatively evaluate the magnetic field distributions in these devices, we can analyze oscillation profiles i...

摘要:We develop proton polarization system for spin-contrast-variation neutron reflectometry using a technique of dynamic nuclear polarization at 3.36 T and 2.5 K. We succeeded in observing polarized neutron reflectivity profiles of a polymer thin film with proton polarization up...

摘要:“Neutron Optics and Physics (NOP/BL05)” at MLF in J-PARC is a beamline for studies of fundamental physics. The beamline is divided into three branches so that different experiments can be performed in parallel. These beam branches are being used to develop a variety of new p...

摘要:We have fabricated spatial resolution test targets made of gadolinium and gold for conventional and resonance neutron imaging at RADEN, located at beam line BL22 of the J-PARC Materials and Life Science Experimental Facility (MLF). RADEN covers a broad energy range from cold neut...
