| 内容記述 | A low-energy positron diffraction (LEPD) experiment station was developed at the Slow Positron Facility, High Energy Accelerator Research Organization (KEK). An electron-accelerator-based slow-positron beam with an energy of 5 keV was magnetically transported and focused on a transmission-type Ni remoderator to achieve a 50 – 500 eV brightness-enhanced beam in a non-magnetic space. A LEPD detector with center holed retarding meshes, Chevron-type microchannel plates, and a delay-line detector (DLD) was installed. A newly developed pulse stretching system was used to stretch the initial positron-pulse width of 1.2-μs to 200 μs - 20 ms to avoid multiple hit events within the position analysis time of the DLD. | |||||
