Surfatron acceleration of the high energy protons in the relativistic jets

Abstract

This paper describes the acceleration of high energies protons captured by electrostatic waves in the frame of jet arising in the area of instability of relativistic jet, where spiral structures are excited. The wave has a spatially heterogeneous structure of $\exp (i{k}_{\parallel }z+i{m}_{\varphi }\varphi )$. Protons can be captured in potential wells created by spiral waves, and thereby experience acceleration with a mechanism known as surfatron acceleration. Expressions of the maximum energy ($E_p\simeq 10^{19}eV$) and the energy spectrum from jet parameters are obtained.
