【摘要】 PSD性能是评价电子储存环真空室材料及材料表面处理优劣的一个重要指标.对一约1.5m长不锈钢管道真空室进行了镀TiN薄膜处理,并在合肥光源机器研究用光束线(MSB)的PSD实验站上对该真空室在镀TiN薄膜处理前后分别进行了PSD性能测试实验研究.测试研究结果表明,镀TiN薄膜处理对于减小不锈钢材料PSD有非常明显的作用.更多还原

【Abstract】 PSD yield is a key criterion to evaluate the vacuum chamber material and its surface pretreatment in an electron storage ring.In this paper,a stainless steel vacuum chamber of 1500 mm in diameter has been tested before and after TiN film coating on PSD experiment station of Machine Study Beamline of NSRL.Test results show that TiN film coating is an effective method to reduce photon stimulated desorption for the stainless steel material.更多还原
