RFQ1L系统压升率的理论与实验研究

Theoretical and Experimental Study on Pressure Rise Rate in RFQ1L

摘要: 简单阐述了RFQ冷却聚束器对缓冲气体的要求，从理论和实验两方面详细研究了RFQ1L系统的压升率。研究表明， RFQ1L系统压升率的主要来源是真空室内材料表面的出气，整个系统的压升率实测为（0.04±0.02） Pa/h。

Abstract: The requirement of the buffer gas in a RFQ (Radiofrequency Quadrupole) cooler and buncher has been introduced briefly. The pressure rise rate of RFQ1L has been studied theoretically and experimentally in detail. It shows that the pressure rise rate of RFQ1L is mainly due to the outgassing of the different materials in the vacuum chamber. The experiments indicated that the pressure rise rate of RFQ1L was (0.04±0.02) Pa/h.
