The transformation coefficient was defined as the ratio of the total wakefield of the sequence to the field that decelerates bunches. In the conducted experiments, the energy spectrum of bunches was measured with a magnetic analyzer before and after the wakefield excitation in the structure. The magnitude of the decelerating field is determined by using the measured shift of the maximum of the energy spectrum and the structure length. The experimentally obtained transformation coefficient is defined as the ratio of the excited accelerating field measured at the 2nd stage to the decelerating field measured at this 3rd stage. It satisfactorily corresponds to the theoretical one, increases with the number of bunches in the sequence and significantly exceeds that for an unprofiled sequence with a resonant structure.  Product Description popup.authors Galaydych Konstantin Viktorovich Linnik Anatolij Fedorovich Onishchenko Ivan Mykolayovych Prystupa Valeriy Ivanovich Sotnikov Gennadij Vasylyovych popup.nrat_date 2023-01-07 Close
