The high current proton beam with continuous energy spectrum and a large divergence angle was generated by using a high contrast laser interacting with micron thickness targets, which later was collected, analyzed and refocused by an electromagnetic lattice using combination of quadrupole and bending electromagnets. This is the first experiment that combines the laser acceleration with a fully functional beam line, realizing the precise manipulation of the proton beams with reliability, availability, maintainability and inspectability . Spread-out Bragg peak (SOBP), the key technology of proton radiotherapy for malignant tumors, is then realized with laser accelerator for the first time.
