C波段磁绝缘线振荡器的理论与实验研究
Abstract
The ically insulated line oscillator(MILO)is a gigawatt—class coaxial crossed
—field microwave primary characteristic ofthe MILO is that it requires no externally applied ic field to insulate the electron flow under the slow wave tube carl pact,lightweight and carl handle all extremely large input beam
dissertation is mainly about the lli曲frequency characteristics of the C—band MILO and the
effect of the ic field and the RF field on the numerical simulation and the experimental research,the structural parameters and working parameters of the C-band MILO are adjusted for incre弱ing the microwave output series of valuable results are obtained.
A two—dimension fully ic Particle-h—Cell rPIe)simulation is applied to study the eigenfrequencies and their field distributions of the relation between the operating frequencies and the structure parameters is obtained,Then we feed power to the system at flae mird cavity and study the high frequency characteristics of the C-band MILO
with open boundary.
Firstly the theoretical analysis of electrons movement in the MILO is made under the condition ofplanar electrode we study the effect ofthe ic field and the RF field on numerical relation between the RF field and spokes is discussed in this paper.
The effects of many structural parameters and working parameters on output power and frequencies are structure of the C—band MILO is designed and
simulation results show that the C-band MILO Can generate an average power of 2GW with the efficiency of 10%at frequency,
In the last part ofthis dissertation,the microwave power,the frequency and the mode are measttred,and the relations between the microwave radiation and beam parameters are
the experiments,the average output microwave power of 500MW with the efficiency of %is got from
