| Summary: | Plasma can support extremely high-gradient strong electromagnetic fields, making it suitable not only for laser acceleration but also for short-distance manipulation of the charged particle beams, thereby enabling the miniaturization of particle accelerators. Straight capillary discharge plasma lenses have previously garnered widespread attention from researchers for their excellent focusing capabilities. We introduced the theory of using a curved capillary discharge plasma channel to deflect charged particle beams [Phys. Rev. Accel. Beams 24, 031301 (2021)PRABCJ2469-9888] and, in this paper, present the first experimental demonstration of plasma-based deflection and focusing of laser-accelerated proton beams. Combined with a dipole magnet, the emittance after transmission was measured, revealing that magnetic field nonlinearity and multiple Coulomb scattering tend to increase the proton beam’s emittance. This work is of great significance for the development of compact beam transport systems. |
