With the advent of chirped pulse amplification technology, laser proton acceleration has rapidly progressed in recent decades. Compared to conventional accelerators, laser proton accelerators have the advantages of subpicosecond temporal distribution and micron source size. These advantages provide widespread potential applications in high-energy-density plasma, such as proton boron fusion study. In the 100-TW laser facility, developments of laser proton acceleration are underway using solid and gas targets, aiming for high-quality proton beam generation. In this work, we will report the progress of proton acceleration via irradiation of micron-PE films with 1.8-J 40-fs laser pulses. Systematic calibration of online diagnostics will be presented. Such proton beam sources will provide unique drivers for proton boron fusion study.
