In Japanese neutron scattering facilities, some SE equipment that are frequently used at an instrument, such as the closed-cycle refrigerator (CCR), have been prepared for the instrument as standard SE. They are operated for user experiments by the instrument group. The advantage of this practice is that they can optimize the design of the SE for the instrument and can directly respond to users' requests. On the other hand, the SE team in the Materials and Life Science Experimental Facility (MLF) in J-PARC has managed commonly used SE to allow neutron experiments with more advanced SE. In this report, recent SE in the MLF is introduced. Highlighted are the SE in BL11, BL19, BL21 and BL17 and other SE recently progressed by the SE team.

Times Cited Count：3 Percentile：45.99(Instruments & Instrumentation)The multilayer structure of Fe/Si and Fe/Ge systems fabricated by ion beam sputtering (IBS) was investigated using X-ray and polarized neutron reflectivity measurements and scanning transmission electron microscopy with energy-dispersive X-ray analysis. The obtained result revealed that the incorporation of sputtering gas particles (Ar) in the Ge layer gives rise to a marked reduction in the neutron scattering length density (SLD) and contributes to the SLD contrast between the Fe and Ge layers almost vanishing for spin-down neutrons. This leads to a possibility of fine-tuning of the SLD for the IBS, which is required to realize a high polarization efficiency of a neutron polarizing supermirror. Fe/Ge polarizing supermirror with 
fabricated showed a spin-up reflectivity of 0.70 at the critical momentum transfer. The polarization was higher than 0.985 for the 
range where the correction for the polarization inefficiencies of the beamline works properly.

Polarized neutron reflectometry is one of the powerful methods to investigate various phenomena on the surfaces and interfaces of a variety of films with layered structures such as magnetic materials. In this instrument, a two-dimensional position-sensitive neutron detection system consists of multi-wire proportional chamber (MWPC) with helium-3 gas and its data reduction software have been developed for the measurement of off-specular reflectivity and grazing incidence small-angle neutron scattering (GISANS). Each wire signal is read out by amplifier-shaper-discriminator (ASD) individually to meet with demands for a fast counting response and high spatial resolution for the measurement at intense pulsed neutron sources. The pitch between anode/cathode wires is 1.0 mm. The spatial resolution was 1.8 mm. We report characterization results of 2-D MWPC system at BL17 and its applications to neutron reflectivity measurements.
