Abstract

Possibility of increase of the transformation ratio at plasma wakefield excitation by long relativistic electron bunch, which charge is shaped according to cosine, with purpose to provide the absence of oscillating (on length of bunch) decelerating wakefield, usually attainable, using bunch - precursor, is considered. Length of bunch is selected more larger than wavelength. It is shown analytically that at the choice of charge shaping of long bunch according to cosine distribution one can do without a bunch – precursor to eliminate oscillating decelerating wakefield. Thus the transformation ratio is just in one and a half times less than in the case with a precursor.
