【Abstract】 The high power RF transmitter and the circulator with 500MHz/250kW which will be operated in Beijing Electron-Positron Collider Upgrade (BEPCⅡ) project have been installed on site, and adjustments and acceptance test have been finished, which is the first transmitter system of 500MHz/250kW in China. In this paper, the test principle and all measurements as well as commissioning result in the acceptance test are introduced in details, and the actual machine technical parameters and performance are presented. An acceptance test conclusion by comparing with the design requirements is given.更多还原
