We recently did the mechanical construction and machining for a device called Pastis3 for Institut Laue Langevin. The Pastis3/PANTHER insert represents the third generation of the PASTIS device, enabling XYZ neutron polarization analysis as an optional upgrade for existing ILL (Institut Laue Langevin) instruments equipped with wide-angle detector coverage. PASTIS-3 utilizes two polarized 3He Neutron Spin Filter Cells (NSF) for the polarization and analysis of neutron spins, flipping the polarization of the incident neutron beam ...
