Estimation of the Electronic Efficiency of a Gyroklystron Amplifier
In the present paper, a generalized self-consistent single mode linear analysis of gyroklystron has been presented. The analysis has been used to estimate and optimize the electronic efficiency of the gyroklystron device. The efficiency contours, necessary for the preliminary design of a gyroklystron, have been drawn by solving the coupled equations using Runga-Kutta method for the various devi...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Experimental Investigation of a W-Band Gyroklystron Amplifier
A four cavity W-band gyroklystron amplifier experiment is currently underway at the Naval Research Laboratory. The gyroklystron has produced 67 kW peak output power and 28% efficiency in the TE011 mode with a 55 kV, 4.3 A annular electron beam. The full width half maximum (FWHM) bandwidth is greater than 460 MHz. Small signal and saturated gains of 36 dB and 29 dB, respectively, have been obser...
متن کاملOptimization the Efficiency of Gas Turbines for Air Pollution Reduction
Increasing concerns about energy and emissions from fuel consumption in gas turbines has attracted many researchers to protect the environment and reduce pollutants in the world. The main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine operation based on the technical analysis of the operation of three-axis gas turbine cycles with non-design condi...
متن کاملInitial Operation of the Maryland Coaxial Gyroklystron Experiment
We describe results from the initial operation of our coaxial gyroklystron experiment, which is being evaluated as a potential driver for future linear colliders. The interaction is designed to occur between a 500 kV, 500 700 A beam and a series of coaxial TE0n1 microwave cavities. Output powers in excess of 100 MW at 8.568 GHz are expected with an efficiency of about 40% [1]. We detail perform...
