Inventor: MATSUDA HISASHI
IPC: H01J49/06
Filed: 1988-02-23
Abstract: PURPOSE:To provide possibility of mass analysis even for ions having a great energy width by developing these ions over the emission surface of uniform electric field according to energy, and allowing an ion sensor having a spatial resolution to be arranged along the convergence surface to sense the ions emitted from the magnetic field and converged according to the mass charge ratio. CONSTITUTION:Uniform electric field 1 in which ions to be analyzed I are incoming from the free space has an intensity E0 in the direction of arrow, and a sector-formed uniform electric field 3 is connected so as to be in connection with the ion outgoing end-face 2 of this uniform electric field 1. Further an ion sensor 4 having space dissolution capability such as a two-dimension sensor using a photographic plate or micro-channel plate is arranged along the ion spreading and converging surface by the mentioned sector-formed uniform electric field 3. Thus mass dispersing magnetic field 3 is arranged so that the incoming surface faces over the whole length of the uniform electric field outgoing surface 2, and even the ions spread in a wide extent by the uniform electric field 1 can be irradiated on the magnetic field without being blocked. This enables to spread into spectrum and sense even though the ions to be analyzed have a comparatively large energy width.
