  Usually large energy spread and shot-to-shot stability are the bottlenecks of laser accelerator in applications. Recently proton beam with energies less than 10 MeV, <1% energy spread, several to tens of pC charge can be stably produced and transported in Compact LAser Plasma Accelerator (CLAPA) at Peking University. The CLAPA beam line is an object-image point analysing system, which ensures the transmission efficiency and energy selection accuracy for proton beams with initial large divergence angle and energy spread. A spread-out Bragg peak (SOBP) is produced with high precision beam control, which is essential for cancer therapy. Other primary application experiments based on laser-accelerated proton beam have also been carried out, such as FLASH irradiation, Laser Ion trace probe, proton radiograph, stress testing for tungsten, irradiation of semiconductor sensor to simulate the space irradiation environment and so on.
