Abstract: We show that both the flux and the cutoff energy of protons accelerated by ultraintense lasers can be
simultaneously increased when using targets consisting of thin layers of bundled nanochannels. Particle-in-cell
simulations suggest that the propagation of an electromagnetic field in the subwavelength channels occurs via
excitation of surface plasmon polaritons that travel in the channels down to the end of the target, sustaining
continuous and efficient electron acceleration and boosting acceleration of protons via enhancement of the target
normal sheath acceleration mechanism.
