Experimental setup.

All IPs are wrapped with 13 μm Al foil. Two tungsten filters with thicknesses of W1 = 25 μm and W2 = 56 μm are placed, respectively, between IP2 and IP3 and between IP3 and IP4 on the laser axis to attenuate the x-ray beam. The consecutive IPs show the dispersed electron bunch. A sample of the plasma channel is shown in the inset above the CCD. The inset in the lower right corner is an example of the experimental electron energy spectrum for nitrogen.
