ELECTRON BEAM SPECTROMETER USING AN FOCUS TYPE ELECTRON PATH BENDING MAGNET ACCORDING TO AN ELECTRON BEAM ENERGY DISTRIBUTION, CAPABLE OF ACCURATELY MEASURING THE ENERGY OF AN ELECTRON BEAM

摘要

PURPOSE: An electron beam spectrometer using an focus type electron path bending magnet according to an electron beam energy distribution is provided to selectively use an electron beam of an energy band by focusing and separating electrons on a specific point from the electron beam according to the energy band.;CONSTITUTION: An electronic beam is inputted between two triangular magnets(2). An electronic beam spectrometer forms a focus path according to energy. A first photosensitive film(3) measures the divergence of the electron beam inputted before using two triangular magnets. A second photosensitive film(4) measures the corresponding position of the electron beam focused on a specific point according to the energy by passing through two triangular magnets.;COPYRIGHT KIPO 2010
