Effect of transition radiation and dispersion spreading at achievement of a large transformer ratio of driver-bunch energy into wakefield in a dielectric resonator accelerator

Effect of transition radiation and dispersion spreading at achievement of a large transformer ratio of driver-bunch energy into wakefield in a dielectric resonator accelerator

Possibility of increase of transformer ratio TR in the case of the profiled sequence of bunches at their injection in a two-beam electron-positron dielectric-resonator collider is considered. Unlike considered earlier the waveguide case, for which TR is equal to the doubled number of bunches of sequ...

Розглянуто можливість збільшення коефіцієнта трансформації TR у разі профільованої послідовності згустків під час її інжекції в двопучковий електронно-позитронний діелектричний резонаторний колайдер. На відміну від розглянутого раніше хвилеводу, для якого TR дорівнює подвійній кількості згустків послідовності, які збуджують кільватерне поле, що обмежене впливом групової швидкості, в резонаторі це обмеження відсутнє. Для отримання в разі резонатора TR, пропорційного кількості згустків, як і у хвилеводі, співвідношення зарядів згустків вибирається рівним 1:3:5:…, довжини згустків рівні половині довжини хвилі, інтервал між згустками кратний довжині хвилі. Методом числового моделювання вивчається вплив перехідного випромінювання і дисперсійного розсіювання на коефіцієнт трансформації. Рассмотрена возможность увеличения коэффициента трансформации TR в случае профилированной последовательности сгустков при их инжекции в двухпучковый электрон-позитронный диэлектрический резонаторный коллайдер. В отличие от рассмотренного ранее случая волновода, для которого TR равно удвоенному числу сгустков последовательности, возбуждающих кильватерное поле, которое ограничено влиянием групповой скорости, в резонаторе это ограничение отсутствует. Для получения в случае резонатора TR, пропорционального количеству сгустков, как и в волноводе, соотношение зарядов сгустков выбирается равным 1:3:5:…, длины сгустков равны половине длины волны, интервал между сгустками кратен длине волны. Методом численного моделирования изучено влияние переходного излучения и дисперсионного расплывания на коэффициент трансформации. 2019 Article Effect of transition radiation and dispersion spreading at achievement of a large transformer ratio of driver-bunch energy into wakefield in a dielectric resonator accelerator / V.I.
