Abstract:
|
In recent , high intensity laser pulse interaction with solid density matter has been studied in several laboratory and facilities . Multi -MeV proton and ion beams from plasma produced by this interaction is one important application research area of HEDP . In this thesis , the basic theory of hot electron generation associated with proton acceleration will be introduced . A basic proton acceleration mechanism called TNSA will be introduced with supplemental free plasma expansion model . To investigate proton acceleration at the Texas Petawatt Facility , the experimental set up and target alignmen will be introduced in the chapter 5 . While the analysis of data acquired from this experiment is still unfinished , a brief result with RCF image will be introduced in chapter 6 . |
