It has been suggested that an inductive element should be added to Watkins RC equivalent circuit for the microwave noise current fluctuations at the potential minimum of a diode, and that this added element gives closer agreement with more recent work which shows a pronounced peak in noise current near the plasma resonance,a = \frac{1}{2}. This paper presents an approximate analytical argument for the inclusion of an inductive element, based on the density-function method of analysis, which…

A physical model of the compensation phenomenon in space-charge reduced shot noise is discussed in some detail and applied first to a planar diode of infinite spacing short-circuited to ac effects.

Parametric Amplifiers

The parametric amplifier was fiJ'st introduced to the microwave field in 1957 by Suhl. In his first paper [Suhl, 1957a], he proposed an equivalent circuit for a cavity type of parametric amplifier.

Measurement of the shot-noise reduction factor

A new method of measurement of the shot-noise reduction factor at microwave frequencies is described. In this method, the reduction factor is measured by using a traveling-wave phototube with

Monte Carlo calculation and measurement of shot-noise reduction factor

The frequency characteristic of the shot-noise reduction factor (R2) of the " O "-type diode is investigated by three methods: the first is a Monte Carlo calculation following the approach of Tien

Some results from the measurement of the noise parameters of an electron beam using a sealed-off tube

Results of the measurement of the noise parameters of an electron beam using a sealed-off tube are presented. The data suggest that the cathode coating resistance plays an important role in



Potential-minimum noise in the microwave diode

An analysis of the potential-minimum region in the microwave diode is presented which predicts the amount of noise convection current at the potential minimum under conditions present in guns of

Noise at the Potential Minimum in the High‐Frequency Diode

Noise quantities at the potential minimum in the high‐frequency diode are analyzed by means of a relatively simple model which assumes that the transit angle from the cathode to the potential minimum

Monte Carlo Calculation of Noise Near the Potential Minimum of a High‐Frequency Diode

Noise near the potential‐minimum of a high‐frequency diode has been calculated in this paper using a high speed electronic, digital computer. Random numbers were generated and used to simulate the

The Effect of Velocity Distribution in a Modulated Electron Stream

A method of solving electron beam problems is described which takes into account the thermal velocity spread. The method is based on the Liouville theorem. Two such problems are solved by means of a
