Abstract :
A nondestructive beam profile monitor using a neutral gas sheet is developed for ion synchrotron beams. To produce the intense gas sheet, a nozzle beam method is employed. The typical sizes of the sheet are 100 mm width and 1 mm thickness. Up to now the pressure of the gas sheet has been achieved 5×10-7 Torr. As the sheet is inclined 45 degrees in the transverse direction to the beam, a cross-sectional profile of the beam would be measured. As a performance test, a profile of an extracted proton beam from NIRS-Cyclotron was successfully measured
