摘要

欧洲散裂源(ESS)在本十年末投入运行时将成为世界上最强大的散裂中子源。ESS直线加速器将在钨靶上以14hz的重复频率以2.86 ms的长脉冲将50mA的质子加速到2gev，用于中子散裂。直线加速器包含26个超导辐条腔，由法国奥赛IPN公司开发，可以将质子从90兆电子伏加速到220兆电子伏。瑞典乌普萨拉大学(Uppsala University)的FREIA实验室已经开发了所需的射频电源，获得了射频分布，并将在标称功率下测试空腔。由于ESS规格(352MHz, 400kWp / 20kWavg，脉冲宽度= 3.5 ms，脉冲重复频率= 14 Hz)没有合适的放大器，因此对各种技术进行了比较，并选择了四极体技术作为FREIA的第一个技术演示射频发电站。我们讨论了技术演示器的设计，并给出了第一次测试结果。

Tetrode based technology demonstrator at 352 MHz, 400 kWp for ESS spoke linac

The European Spallation Source (ESS) will be the world's most powerful spallation neutron source when it comes in operation at the end of this decade. The ESS linac will accelerate 50mA of protons to 2 GeV in 2.86 ms long pulses at a repetition rate of 14 Hz on a tungsten target for neutron spallation. The linac contains 26 superconducting spoke cavities, which are being developed by IPN Orsay, France, and which accelerate the protons from 90 to 220 MeV. The FREIA laboratory at Uppsala University (Sweden) has developed the required RF power sources, procured the RF distribution and will test the cavities at nominal power. As no suitable amplifier was available at the ESS specifications (352MHz, 400kWp / 20kWavg, pulse width = 3.5 ms, pulse repetition frequency = 14 Hz), various technologies were compared and tetrode technology was selected for the first technology demonstrator RF power station at FREIA. We discuss the design of the technology demonstrator and present the first test results.
