TLDR
A simple linear theoretical model is developed, which can explain most of the observed phenomena, except for the large-amplitude oscillations of the wave envelope.Abstract:
Plasma wake fields in the ion-wave regime have been excited by injecting ion bunches with a variety of shapes. An excited-wave amplitude (\ensuremath{\delta}n/${\mathit{n}}_{0}$) of up to 17% has been observed for a bunch falloff time less than the wake-field period. The large-amplitude wake wave damps out, along with oscillations of the wave envelope. A simple linear theoretical model is developed, which can explain most of the observed phenomena, except for the large-amplitude oscillations.read more

Analytical calculations of wake field generated by microwave pulses in a plasma filled waveguide for electron acceleration
TL;DR: In this article, a feasibility study on wake field with rectangular pulse and its combination with Gaussian and triangular pulses under the effects of microwave pulse parameters and waveguide dimensions was carried out, and it was inferred that the wake field in the waveguide cannot be attained when the length of rectangular microwave pulse is exactly equal to the plasma wavelength.

Excitation of wakefield in a rectangular waveguide: Comparative study with different microwave pulses
TL;DR: In this article, a differential equation governing the wakefield potential in a plasma filled rectangular waveguide is derived analytically for three kinds of microwave pulses, namely sine pulse, rectangular Gaussian pulse, and rectangular triangular pulse (RTP).
