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.
PSD performance is an important index to evaluate the surface quality of materials and materials in the vacuum chamber of electronic storage ring.A TiN thin film was processed on a stainless steel pipe vacuum chamber of about 1.5m in length, PSD experiments were performed on the vacuum chamber before and after the TiN film was plated.The results of the test show that the TiN film treatment has a significant effect on reducing the PSD of the stainless steel material.
