NSRL储存环真空系统的改进

摘要

To increase the beam lifetime to more than 600 minutes for the 800MeV/300mA storage ring in NSRL, some improvements on the vacuum system are necessary. The present condition of the vacuum system is analyzed and several important improvements to be brought about are described in detail.%为了达到储存环能量800MeV时储存流强300mA时的束流寿命600min以上，详细分析了NSRL真空系统的现状和对真空系统改进设计。
