“…9 was unnecessarily detailed for a weakly relativistic and low current beam. Therefore a reduced model 14 based on a single mode sinusoidal or Gaussian axial profile for the "cold" field could be used. Although reduced models of gyroklystron amplifiers are still useful for understanding the basic operation of these devices, they are not adequate as a design tool if the combination of the highest possible bandwidth and efficiency is desired.…”

Modeling and design of millimeter wave gyroklystrons

A series of high power, high efficiency Ä^-band and W-band gyroklystron experiments has been conducted recently at the Naval Research Laboratory (NRL). Stagger tuning of the cavities for bandwidth enhancement is commonly used in the conventional multicavity klystrons. The desired stagger tuning is usually achieved via mechanical tuning of the individual cavities. However, in the millimeter wave regime, particularly, in the case of the high average power operation, it is desirable to be able to achieve the required stagger tuning by design. The NRL gyroklystron experiments explored the tradeoffs between power, bandwidth, efficiency, and gain to study the effects of large stagger tuning in millimeter wave without resorting to mechanical tuning of the cavities. Both, K^-band and W-band, experiments demonstrated a record power-bandwidth product. The success of the experiments was due in large part to a battery of improved large-signal, stability, and cold test codes employed in the modeling and design stage. Theoretical models that provide the basis for these design simulation tools and the design methodology will be presented. © 7999 American Institute of Physics. [S1070-664X (99)

“…Anharmonicity means that the vibrational frequency of the oscillator depends on its energy: = ͑E͒. According to Gaponov [3,4] (see also a simplified explanation [13]) such a dependence is a key physical reason of phasing. Maxwell's equations describe the electromagnetic field in CMS.…”

On the basis of the results of numerical modeling, it is shown that dipole-dipole interactions among atoms in the active medium strongly influences the character of the associated superradiation. The main effect is to make the nuclear subsystem behave chaotically. Its strength increases with the atom density and leads to the suppression of distant collective correlations and superradiation. Near correlations between the atoms are established, causing a confinement effect: a shielding of radiation in the active medium.
