High frequency amplifying apparatus with a collector which has a periodic amplitude variable longitudinal magnetic field therein |
摘要 |
In a klystron, or other device which uses modulation of an electron beam to produce amplification of an applied high frequency signal, a collector is used to receive electrons of the beam after the amplified signal has been coupled from the device. Any secondary electrons produced by the impact of high energy electrons on the collector surface are prevented from returning back along the klystron by a periodic magnetic field produce by magnets which coaxially surround the collector.
