Sv. Grigoriev et al., PECULIARITIES OF THE CONSTRUCTION AND APPLICATION OF A BROAD-BAND ADIABATIC FLIPPER OF COLD NEUTRONS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 384(2-3), 1997, pp. 451-456
An available mathematical model for calculation of a broadband adiabat
ic flipper for cold polarized neutrons is suggested. This model of the
sine-cosine modulation of an effective field enables one to optimize
and to simplify the calculation for constructing the flipper. A functi
onal relation between spin flip probability and the main parameters of
the device such as the length of the flipper, the neutron wavelength
and both form and size of the magnetic fields have been found. Tests o
f flippers constructed on the base of this model has been successfully
carried out.
