Title: Metal ion source
Inventor: AIHARA RIYUUZOU
IPC: H01J37/08
Filed: 1981-09-04
Abstract: PURPOSE:To obtain a metal ion source for producing the stable ion beam for long term, by providing a filament thermally connected to the reservoir section or the needle member and heating the ionizing metal, while employing such shape as the high temperature region will occur at a portion. CONSTITUTION:A portion of the filaments 11a, 11b spot welded to the reservoir 1 containing gallium 3 is folded into a hair pin and heated with higher temperature than that at the filament section except at the folding sections 12a, 12b. Since the gallium spread to the surface at the outside of the reservoir 1 has the higher temperature at the folding sections 12a, 12b of the filament than at the reservoir 1, it is not diffused on the surface of the filament in the direction of the support 9. Consequently the liquid metal block of filament is not produced and the electrical resistance will not drop considerably, thereby the gallium 3 can be heated to desired temperature and the gallium in the reservoir can be transferred stably to the tip of the needle member 4.
