| 内容記述 | Acceleration of particles from the interaction of ultra-intense laser pulses of 1021 W/cm2 level with thin metal foils is investigated experimentally. To determine the laser-produced plasma condition is one of the keys to understand the physical processing and acceleration mechanism. For the purpose, an X-ray spectrometer with elliptical curved Germanium crystal is designed. The crystal was installed into a specific position which can collect the X-ray from the target and reflect the dispersive emission on the image plate. In the experiment, we observed the Au spectrum about 3-6 KeV range using 25-500 nm thickness Au foil targets. The Ni-like Au M-shell spectrum is recorded which is used to analyse the plasma temperature and density in this ultra-intense laser acceleration experiment. Together with the simultaneously measured data of X-ray single photon counting (SPC) system observing 2 to 20 keV energy range, estimate the plasma electron temperature and density using the spectrum data and compare them with theoretical calculated results under non-local thermodynamic equilibrium (NLTE) condition. We will present the detailed laser condition, diagnostic setup and experimental condition. The process between the plasma heating and particles acceleration in the different foil thicknesses will be discussed. showing that the high temperature solid density plasma condition achieved by the ultra-intense short-pulse laser at high intensity limit is crucial for producing highly charged high energy ion beam. |
