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.
