Peculiarities of the construction and application of a broadband adiabatic flipper of cold neutrons

An available mathematical model for calculation of a broadband adiabatic 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 functional 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 of flippers constructed on the base of this model has been successfully carried out.
