雷射電漿質子加速器應用之可行性研究(1/2)

The aim of this project is to study the feasibility of using laser plasma accelerators for applications such as aneutronic fusion, proton therapy for cancer treatment, and nano-material processing through theoretical calculations and numerical simulation. The required beam quality for different applications significantly varies, for example, proton therapy requires proton beam energy exceeding 100 MeV with a low energy spread, while aneutronic fusion, such as proton-boron fusion, does not require such high single proton energy, but rather a large number of particles. The nano material processing requires a proton beam with small energy spread and angular distribution. Using the particle-in-cell method, we can obtain the optimal beam quality and the scaling law by scanning different laser and plasma parameters. We can also derive a theory for accurately predicting the maximum energy of the proton beam. Finally, we use Monte Carlo simulation to simulate the physical processes of charged particles in the target and present all the parameters required for the experiment and predict the final results. The establishment of this model is crucial for the establishment and related applications of advanced proton sources in Taiwan.
