Abstract: A unit for creating in the area of the analyzed sample a pulsed microwave field with a 2.45-GHz frequency, a 10-ns fall time, and a rotating component of the magnetic induction with a maximum amplitude of 0.8 mT is described. The fast pulse decay is obtained by creating a pulsation mode in the system consisting of two coupled resonators. The duration of the flat top of the microwave pulse is regulated from 0 to 400 ns, and the maximum pulse repetition rate is 16 kHz. The unit is used in the nanosecond X-ray fluorimeter to control the spin state of the spin-correlated ion-radical pairs in nonpolar solutions. [ABSTRACT FROM AUTHOR]
