However, present analytical model is only suitable when beam size and hosing amplitude is much less than plasma blow-out radius. By developing a physically simple model which incorporates the single particle betatron motion and particle loss due to large betatron amplitude, this work demonstrates that the asymmetric particle loss due to the phase mismatch between beam hose and plasma respondency can damp hosing amplitude in magnitudes with negligible beam loss. We find excellent agreement between our model and 3D particle-in-cell simulations. Besides, for wide driver, we achieve stable propagation when transformer ration is about 5, which is almost impossible based on the previous understanding. PB - JACoW CP - Geneva, Switzerland ER -
