    "abstract": "We present an investigation of the electromagnetic instabilities which are\ntrig gered when an ultra relativistic electron beam passes through a plasma.\nThe linear growth rate is computed for every direction of propagation of the\nunstable modes, and temperatures are modelled using simple waterbag\ndistribution functions. The ultra relativistic unstable spectrum is located\naround a very narrow band centered on a critical angle which value is given\nanalytically. The growth rate of modes propagating in this direction decreases\nlike k^(-1/3).",
