SOME FREQUENCY AND POWER CONVERSION PROPERTIES OF CYCLOTRON WAVES,
Abstract
Adler tube type devices are considered. Fast cyclotron waves at one or several discrete frequencies are excited on the electron beam by the use of a Cuccia coupler. The modulated beam is shot through a 2n-pole where, contrary to the usual pumping procedure, power is extracted from the cyclotron waves. An analysis of the frequency and power conversion properties of a cyclotron wave excited 2n-pole is carried out. An experiment was made where an electron beam, carrying fast cyclotron waves of frequencies, was shot through a quadrupole. Finally an Adler tube with two quadrupoles between the input and output Cuccia couplers is considered. One of the quadrupoles extracts a fraction of the signal power at twice the signal frequency and serves as the source of the pump voltage which is fed to the other quadrupole via an external amplifier. Thus the pump voltage is phase locked to the signal. The properties of the basic types of this amplifier are discussed. (Author)
