新西伯利亚Budker INP设计的VEPP-2000正负电子对撞机是一台能量为1GeV、单束流阈值为200 mA的新型储存环。为了实现束团相位运动的稳定性和抑制光束与高阶模的相干相互作用,研制了一种单模172 MHz加速腔。该腔在HOM处具有200 Ω ~ 300 Ω的低耦合阻抗。文中介绍了谐振腔的设计和所用的HOM载荷。
VEPP-2000 electron–positron collider designed in Novosibirsk Budker INP is a new storage ring with 1 GeV energy and 200 mA current threshold per beam. For a bunch phase motion stability and suppression of a beam coherent interactions with higher order modes (HOM) a single-mode 172 MHz accelerating cavity is developed. The cavity has a low coupling impedance of 200÷300 Ohm at HOM. The cavity design and used HOM loads are described in the paper.
