SwissNeutronics provides a wide range of devices for neutron beam polarization and polarization analysis, including V-cavities, benders, WAPAs and Heusler monochromators. RF spin flippers enable precise selection of the desired spin state across a broad wavelength range. Combining V-cavities with an RF flipper creates a turnkey spin-selector solution. All devices deliver consistent performance and are completely maintenance-free.
Polarizing cavities use spin-dependent neutron transmission through supermirrors on silicon wafers. One spin state is transmitted, the other reflected. V-shaped wafer arrangements shorten the device length. Multiple parallel channels cover wider beams, while serial V-configurations enhance polarization efficiency—ideal for experiments…
Wide Angle Polarization Analyzers (WAPAs) analyze neutron polarization using either reflection (rWAPA) or transmission (tWAPA) geometries. rWAPAs use Fe/Si-coated lamellas; tWAPAs employ V-shaped cavities. Covering wide angular ranges, WAPAs offer stable, maintenance-free operation and high efficiency, making them ideal for…
Polarizing benders polarize neutron beams across a wide wavelength range. Macro benders use curved, supermirror-coated guides; micro benders are compact, using bent thin boron glass lamellas. Solid-state benders with Si wafers offer high efficiency in transmission geometry, while reflection geometry…
SwissNeutronics provides advanced spin-selectors for neutron polarization, featuring RF spin flippers with no beam obstruction and polarizing cavities achieving ~99% polarization and ~35% transmission. Cavity configurations include serial and parallel V setups, with thin Si wafers and simulation tools (McStas)…
SwissNeutronics’ Heusler monochromator system features individually controlled magnetic yokes for uniform fields over 1.4 kG, achieving neutron polarization above 94%. It offers high angular precision, motorized alignment via goniometer stages, and modular design with integrated shielding and guide fields—ideal for…
