Developments and Applications of Super Strong Permanent Magnet, New turns for Linear Collider and Neutron Optics

点击翻译按钮获取中文摘要

We have been developing final focus lens for a linear collider and focus lens for neutrons with super strong permanent magnet technique. An adjustable quadruple magnetic lens of 5-ring-singlet was successfully beam-tested at ATF2 beamline. Sextupole magnets with modulating capability have been also developed for neutron focusing. The second model was tested at ILL, Grenoble, with Very Cold Neutrons, where pulsed white beams were successfully focused. SANS experiments with this beam proved that a very compact VCN-SANS with high resolutions can be feasible.
