The objective of the project is the design of a hollow-beam klystron with a rotating field in themodulating resonator, such that a helix shaped beam develops. That allows for higher currents,larger resonators, a higher output efficiency and a very efficient frequency multiplication.The project is supported by the DFG since 1.9.2012. A first design of a 10GHz klystron with 50%efficiency and 49dB gain is well advanced. Also, first results for a w-band klystron were achieved.The work was performed with in-house developed codes for particle tracking and particle-in-cellsimulations.The continuation of the project shall treat the design of an x-band klystron with higher azimuthalmodes, thus creating 3 or 4 helix shaped interwoven beams suited for very high powers (MW). Atw-band and for medium power (some 100W) a frequency tripling device shall be investigated, with30GHz input and 90GHz output resonators. In addition, work on the hollow-beam cathode has to becontinued.

该项目的目标是设计一种在调制谐振器中具有旋转场的空心光束速调管，从而形成螺旋形光束。这允许更大的电流，更大的谐振器，更高的输出效率和非常有效的频率倍增。该项目自2012年9月1日起得到DFG的支持。第一个具有50%效率和49dB增益的10GHz速调管的设计是非常先进的。此外，取得了w波段速调管的第一个结果。这项工作是用内部开发的粒子跟踪和细胞内粒子模拟代码完成的。该项目的后续工作将处理具有更高方位角模式的x波段速调管的设计，从而创建适合于非常高功率（MW）的3或4螺旋形交织梁。在w波段，对于中等功率（约100W），应研究使用30ghz输入和90GHz输出谐振器的三倍频装置。此外，空心束阴极的工作还必须继续进行。
