An ultraintense laser, injecting a 10J of power at 1.053 μm in 0.5 ps into a glass capillary, which induced electron acceleration, was analyzed. The length of the plasma was longer than any gas jet plasmas. At 60 MeV, a small energy peak is observed, suggesting the electron trapping in the wakefield. The trapping effect is supported both at the middle energy shoulder and at the high energy bump around maximum by 1D-and 2D-PICs. The resonance feature of the laser wakefield shows the gain dependence on the bore size.
