A non-conventional multi-stage depressed collector for high efficiency applications

Non-conventional 3-stage collector geometry has been designed using EGUN code for high efficiency applications deviating from typical 4-stage depressed collector. Efficiency of this collector is very much similar to 4-stage collector with reduced dimensions, weight, etc, which are very important if such collector is to be used for space applications. Such collector also reduces the complexity of electronic power conditioner (EPC) for the TWT. Practical feasibility for fabrication has also been studied by developing the model in solid-works.
