An ion neutralizer enhances a heat transfer rate between a reflecting plate and a frame while preventing the reflecting plate from being bent due to thermal deformation. Also included is a computer processor executing the instructions on the memory device to perform the steps of selecting a sub-routine to be called by a calling unit. This method is designed to lower the cost of deformational treatment for long rods and large diameter billets and creates a pre-specified microstructure, including micro-crystal structure, and specific physical and mechanical properties. The third data transfer means supplies the setting data to each of the plurality of the processing units individually. The collecting tube is connected by tack weld seams with the collector before brazing the collecting tube and the collector together.
