PIC simulation of S-Band Magnetically Insulated Line Oscillator

Abstract

Magnetically Insulated Line Oscillator (MILO) is a relatively new type of coaxial crossed field electron beam device designed specifically to generate microwave power at the gigawatt level. Unlike other crossed-field microwave sources, the MILO uses the self-magnetic field produced by current flow in the central cathode rather than the field produced by an external magnet to cut off electron flow to the anode. In the present work, a S-Band MILO has been designed with voltage 180kV, current 35kA at frequency 2.6 GHz. It was composed of four cavities acting as slow wave structure, one extractor and three choke cavities. Using MAGIC PIC simulation code, the deive is simulated for its hot performance and found the desired power output at the designed frequency with efficiency of device is 10%.
