An. Bazhenov et al., AN ADIABATIC RESONANCE SPIN-FLIPPER FOR THERMAL AND COLD NEUTRONS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 332(3), 1993, pp. 534-536
A device to reverse the polarization of a wide velocity spectrum neutr
on beam is described. The method does not require the switching of sta
tic magnetic field or presence of a matter in the neutron beam. The ne
utron beam need not to be strongly collimated. The probability of spin
flip is close to 1. The schematic of a simple radio frequency current
generator for the flipper solenoid is presented.
