| 内容記述 | In this study, the micron-size hydrogen clusters were generated by expanding the supercooled high-pressure hydrogen gas into a vacuum via a conical nozzle connected to a solenoid valve cooled by a cryogenic refrigerator. The size distribution of the hydrogen clusters is evaluated by measuring the angular distribution of laser light scattered from the cluster. The data were analyzed based on Mie scattering theory combined with Tikhonov regularization method. The size distribution of the hydrogen clusters was found distributed from 0.3-2.0 um. The background gas density profile of the targets is also evaluated using a Nomarski interferometer assuming the cylindrical symmetry of the target. The 3D Particles-in-Cell (PIC) simulations concerning interaction processes of micron-size hydrogen clusters with high power laser pulses predict the generation of protons exceeding 100 MeV, accelerated in a laser propagation direction via an anisotropic Coulomb explosion mechanism, demonstrating a future candidate in laser-driven proton sources with the upcoming multi-PW lasers. |
