A new spin-flipper with a prolonged working area for non-monochromatic neutron beams

Neutron Zeeman beam-splitting for the investigation of magnetic nanostructures

“…Time-of-flight (TOF) method is used for the determination of neutron wavelength. The parts of the experimental setup are following: the curved long (5 m length) FeCo polarizer [29], non-adiabatic spin-flipper of Korneev type [30,31], the sample with a vertically oriented surface placed between the poles of the electromagnet, the second adiabatic radiofrequency spin-flipper [32] with a diameter of 100 mm, the multislit curved supermirror analyzer with working area 38×40 mm 2 . The neutron beam is registered by a one dimensional 3 He position-sensitive detector (PSD) with the working area 120(horizontally)×40(vertically) mm 2 and a spatial resolution of 1.5 mm [33].…”

Polarized neutrons for pulsed neutron sources

“…The neutron spin cannot follow this fast field change and is therefore reversed relative to the guide field direction at the exit of the flipper. Besides the coaxial configurations, other geometries were realized to achieve similar results, like the coplanar rectangular coils configuration transverse to the beam proposed by Korneev [91].…”

On the Application of Zeeman Spatial Beam Splitting in Polarized Neutron Reflectometry

“…The cross section of the polarized beam at the exit of the polarizer was 2.5(horizontal)×60(vertical) mm 2 . The polarization of the beam before the sample was reversed by nonadiabatic spin-flipper (SF1) of Korneev type [23,24]. The sample (S) was placed between the poles of the electromagnet (EM).…”
