WG8 - Advanced and novel accelerators for High Energy Physics

talk

Focusing of electron and positron beams in collider is important [1-7]. The focusing mechanism in the plasma, in which all electron bunches are focused identically, has been proposed [5-7]. This lens is researched by simulation by lcode [8] in this paper for short positron bunches. It is shown that there are two lenses. It is necessary that in one case the length of 1st bunch should be equal...

WG8 - Advanced and novel accelerators for High Energy Physics

talk

Being promising alternatives to conventional accelerators and for application to high-energy physics also linear colliders, it is crucial for plasma accelerators to accelerate positrons, which is much more challenging than electron acceleration that most current researches focus on.

Plasma electron motion is one main source of beam quality degradation for positron acceleration in...
