Experimental study of wakefields driven by a self-modulating proton bunch in plasma

Patrick Blanchard, Ambrogio Fasoli, Alan Howling, Ivo Furno, Yanis Andrebe, Sun Hee Kim, Rémy Jacquier, Ishkhan Gorgisyan, Riccardo Agnello, Yiming Li, Shuai Liu

We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growth and amplitude increase with increasing seed amplitude as well as with the ...

Proton Bunch Self-Modulation in Plasma with Density Gradient

Patrick Blanchard, Ambrogio Fasoli, Alan Howling, Ivo Furno, Samuel Rey-Mermet, Yanis Andrebe, Ishkhan Gorgisyan, Amarasinghage Tharindu Dasun Perera

We study experimentally the effect of linear plasma density gradients on the self-modulation of a 400 GeV proton bunch. Results show that a positive or negative gradient increases or decreases the number of microbunches and the relative charge per microbun ...
