Abstract
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.
