上海光源(SSRF)是一台能量为3.5GeV的中能第三代光源.储存环的设计束流是300mA,总的束流功率约625kW,借鉴国际先进经验,从THALES等公司引进500MHz 300kW(CW)高频发射机(包括速调管和相应的PSM型电源)及350kW(CW)环流器等作为三套高频功率源的主体,一一供给三套超导高频腔,加速电子以补偿其同步辐射以及其他功率损耗.近一年来我们完成了储存环高频厅和其水冷、风冷、配电系统的建设,4台速调管的制造厂验收测试,三套发射机的就位安装和调试,第一套发射机的现场验收测试,第一台环流器的安装和高功率验收测试,第一套高频功率源的高功率传输系统在不同反射相位下的满功率老炼.第二、三套发射机的现场验收测试正在进行中,预计10月份全部完成.迄今为止所有的验收项目均达到技术指标.本文简要地叙述了SSRF高频功率源的选型、技术指标、设计方案、总体布局,重点介绍了现场验收测试的结果.
Shanghai Light Source (SSRF) is a mid-energy third-generation light source with 3.5GeV energy.The design of the storage ring is 300mA, the total beam power is about 625kW, drawing on international advanced experience, the company introduced 500MHz 300kW CW) High-frequency transmitters (including klystron and corresponding PSM power supply) and 350kW (CW) circulator as the main body of three sets of high-frequency power supply, one by one supply three sets of superconducting high-frequency cavity to accelerate the electron to Compensate for its synchrotron radiation and other power losses in the past year we completed the storage ring HF Hall and its water-cooled, air-cooled, power distribution system construction, 4 sets of klystron factory acceptance test, three sets of transmitters Bit installation and commissioning, the first set of transmitter field acceptance testing, the installation of the first circulator and high power acceptance testing, the full power burn-in of the first high power transmission system of high frequency power at different reflections The second and third sets of transmitter field acceptance testing are underway and are expected to be completed in October, so far, all the acceptance projects have reached the technical indicators.This article briefly describes the selection of SSRF high frequency power source, technical indicators, Design, overall layout, heavy Point introduced the results of field acceptance testing.
