In this Final Technical Report the results of a three years research effort directed toward the theoretical study of noise in crossed-field beams is presented. The major findings of this study are 1 The only noise growth mechanism identified by the model in the gun region of a crossed-field beam is that due to the diocotron effect. 2 In order to reduce the noise arising in the gun region of a cross-field beam, it is important that the entire cathode be operated in the temperature limited regime with focusing and other electrodes designed to give smooth, noncycloiding beams.
