a The sketch map of the CBET experiment setup with the laser pulse. Blue solid line represents the power of inner beams and red solid line represents the power of outer beams. The x-ray radiation flux is measured by a Space-resolving Radiation Flux Detector (SRFD). b The arrangement of 24 beams and their polarizations at lower hemisphere for case IV. The arrows indicate the direction of polarization projected onto the plane of laser entrance hole for each beam. The incident angles from outer to inner cones are 55∘ (blue), 49.5∘ (cyan), 35∘ (pink) and 28.5∘ (red), respectively.
