英文摘要 | the propagation of fast electrons produced in the interaction of relativistically intense, picosecond laser pulses with solid targets is experimentally investigated using k-alpha emission as a diagnostic. the role of fast electron refluxing within the target, which occurs when the electrons are reflected by the sheath potentials formed at the front and rear surfaces, is elucidated. the targets consist of a cu fluorescence layer of fixed thickness at the front surface backed with a propagation layer of ch, the thickness of which is varied to control the number of times the refluxing fast electron population transits the cu fluorescence layer. enhancements in the k-alpha yield and source size are measured as the thickness of the ch layer is decreased. comparison with analytical and numerical modelling confirms that significant refluxing occurs and highlights the importance of considering this phenomenon when deriving information on fast electron transport from laser-solid interaction experiments involving relatively thin targets. |
