Abstract:

The calculation of noise in a parametric cyclotron-wave amplifier of the quadrupole type is presented. The analysis is correct to second order in the pump amplitude. The calculated noise temperature of the amplifier consists of two terms, the first being proportional to the cathode temperature, and the second proportional factor gamma squared where gamma squared is the space-charge smoothing factor accounting for the smoothing of position noise taking place at the potential minimum in front of the cathode. It is shown, by design parameters for three different tubes, that the noise temperature of the parametric quadrupole amplifier seems to increase rapidly with frequency. The noise temperature is also shown to be proportional to the pump power. Author
