We have developed a compact permanent-magnet sextupole lens for neutrons that can focus a pulsed beam with a wide wavelength range—the maximum wavelength being more than double the minimum—while sufficiently suppressing the effect of chromatic aberration. The bore diameter is ø15 mm. Three units of a double-ring sextupole with a length of 66mm are cascaded, resulting in a total length of 1…
