摘要

本文介绍了采用热解法石墨阴影栅的多束ku波段速调管和采用铪阴影栅的同类型速调管的实验研究结果。与铪栅格相比，热解石墨的高抗发射特性使热离子电流从15-30 mA降至零。这使得速调管在较低的非占空比值下稳定运行，与具有铪阴影栅格的速调管相比。

Study of Miniature Ku-Band Multiple-Beam Klystron with Built-in Shadow Grid of High-Density Pyrolytic Graphite

The results of experimental studies of multiple-beam Ku-band klystron with a pyrolytic graphite shadow grid and klystron of the same type with a hafnium shadow grid are presented. The high antiemissive properties of pyrolytic graphite give a decrease in the thermionic current from 15–30 mA to zero compared to the hafnium grid. This allowed for stable operation of the klystron at lower values of the off-duty ratio compared to the klystron with a hafnium shadow grid.
