Proton Bunch Self-Modulation in Plasma with Density Gradient

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

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 ...

Experimental Observation of Plasma Wakefield Growth Driven by the Seeded Self-Modulation of a Proton Bunch

Gennady Plyushchev, Yiming Li, Sijie Liu, Michele Marin, Sun Hee Kim, Ishkhan Gorgisyan, Shuai Liu

We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1 x 10(14) and 7.7 x 10(14) electrons/cm(3). We show that these wakefields periodically defocus the proton bunch itself, consistently with t ...

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

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

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 ...
