Trajectory and profile of the beam at a mono-beam energy of 500 eV with a 1 mm exit slit in the residual gas mode and an electric field of 885 V cm−1. The trajectory on the 2D image and the profile were obtained by accumulating and averaging (a) a single X-ray pulse, (b) ten X-ray pulses and (c) 100 X-ray pulses. |
