| 摘 要： | Forward fast protons are generated by the
moderate-intensity
laser--foil interaction. Protons with maximum energy 190~keV are
measured by using magnetic spectrometer and CR-39 solid state
track detectors along the direction normal to the rear surface.
The experimental results are also modeled by the particle-in-cell
method, investigating the time-varying electron temperature and
the rear sheath field. The temporal and spatial structure of the
sheath electrical field, revealed in the simulation, suggests that
these protons are accelerated by target normal sheath acceleration
(TNSA) mechanism.
