Illuminating a 40TW chirped pulse amplified laser on 0.01 critical density hydrogen plasma, we obtain a self-modulated wavefield in the relativistic region, whose amplitude is 24 percent of the average density, or the accelerating field is 160 GV/m. The laser beam is relativistically self-focused, which in turn confined the plasma wave within 0.4 mm diameter over 1 mm axial length. The dephasing distance implies an electron acceleration to 48 MeV, which is consistent with the observation of the averaged energy 35 MeV. Protons of 7 MeV are observed.
