1. Plasma : high electic field can accelerate electron and proton laser plasma accelerator can reduced size of future accelerator can produced particle beam with parameters than conventional accelerators cannot. Electron beam can drive plasma wave and 10 GeV has been achieved ( private communication from C. Joshi) : 10 GeV in 30 cm injected 28 GeV electron beam Need of founding for improving laser parameter increase collaboration with accelerators physicist many applications (medical, material science, chemistry, etc…)
