Abstract :
A new scheme for beam extraction is presented to partially extract a negative hydrogen ion beam at 260 MeV from the main linac where both protons and negative hydrogen ions are accelerated up to 1 GeV. The negative hydrogen ions are extracted by a stripper magnet and the un-extracted ions are returned to the linac. The main feature of this extractor is its ability to regulate the intensity of the extracted beam with the stripper magnet. This extraction scheme will be utilized for the KOMAC (Korea Multi-purpose Accelerator Complex) linear accelerator of 1 GeV cw proton (H+)/negative-hydrogen (H-) beams with an intensity of 20 mA
