Description

In order to apply the 3He neutron spin filter (NSF) to experiments at an intense pulsed neutron experimental facility such as the J-PARC, it is important to make the system stable, useful and easy to setup and operate, because the system is located inside a radiation shield for high energy gamma ray and neutrons. In this study, we have developed compact laser optics with a volume holographic grating (VHG) element for a spin-exchange optical pumping (SEOP) system, and composed an in-situ SEOP 3He-NSF. The details of the setup and its performance are reported. (author)
