Vacuum is a core technology in accelerators, and the latest accelerator is full of next generation vacuum technologies. In order to solve the problem at each stage of the high intensity proton accelerator, such as stable beam supply from the ion source, suppression of discharge in the acceleration cavity, reduction in beam loss, suppression of pressure increase due to particle desorption from the surface, the vacuum is a key technology. In this manuscript, we will explain the vacuum technology in the high-intensity proton accelerator with J-PARC Linac and 3 GeV synchrotron as examples.
