Ion extraction and collecting character under different voltage, the relation of collecting time with shield stripping, and collision and sputtering effect were simulated.
There are two kinds of supply modes of collecting electrode resistance (inner and outer) in the voltage-steadied circuit in which series connection transistor is used.
