Design goal :-Increased Yield By 50%. -Low and quick maintenance cycle. -Suitable to Multi-geometrical internal volume Chamber. -Stand alone uPLC- PC GUI. -Low cost High reliability.
Future Projects:-New valves layout for less radiation damage.-One isolation foil used in grid flange, Water cooled, no helium.
