Abstract Recent vacuum system development with an XHV condition for the particle accelerators is briefly described. The progress of selecting and treatment of the materials used in XHV systems is introduced, and the choice of the main pump for an XHV system and some new pumping method are presented. Some leak detection experiences both for the superconducting and warm vacuum systems are recommended and the status of XHV measurement and the gauge calibration are introduced. Key words particle accelerator, extreme high vacuum (XHV), gasload
