The linac of SHINE facility is superconducting accelerat-ing structures of high gradients, whose performance is closely related to the cleanliness of superconducting cavities. Therefore, the beam line vacuum system has extremely high requirement for particle free to avoid particles down to submicrometric scale. To control parti-cle contamination, particle-free environment has been built for cavity string assembly and other beam line vacuum components installation, clean assembly criteri-on has been established. Furthermore, the particle gener-ation of vacuum components (valve, pump, et al.) has been studied. Moreover, dedicated equipment and com-ponent (slow pumping & slow venting system, non-contact RF shielding bellow) have been developed for particle-free vacuum system.
