Description

<p>At the end of May in 2008, the first neutron was produced successfully at a spallation neutron source in Japan Proton Accelerator Research Complex (J-PARC) Materials and Life Science Experimental Facility (MLF), the following June, SuperHRPD recorded the world's highest resolution of Δd/d = 0.0353(3)%. We used the existing Sirius vacuum scattering chamber at the KENS facility to complete the commissioning as quickly as possible. During the summer shutdown in 2009, a replacement to a new vacuum scattering chamber was carried out. The new vacuum chamber was designed and installed successfully, with ingenuity to allow for efficient construction in a small experimental building for BL08 and technical issues to achieve even higher resolution and low background.</p>
