Outline of Final Research Achievements |
It was demonstrated by using the LFEX laser system at the Institute of Laser Engineering, Osaka University for the first time to generate abundant electron-positron pairs through the Bethe-Heitler process. It was shown that the control of the pulse contrast and pre-forming plasma is important and essential to maximized the efficiency of pair creation. Following elements for the future study to create and investigate the electron-positron plasmas were developed in this project. 1) Plasma mirror system for the LFEX laser to decrease the pre-pulse level and separate focusing of the four beams from the LFEX. 2) New diagnostics were developed and installed on the LFEX such as high energy x-ray spectrometers with new design concepts and an imaging system for the scattered light. 3) A new remedy to avoid the run-away solution of radiation friction was introduced and relativistic PIC codes have been developed to investigate the pair-creation by ultra-high intense lasers.
