【Abstract】 A non-focusing magnetic spectrometer design for electron scattering in medium energy region is proposed. The positions read out from the position-sensitive detectors in the spectrometer are used for track reconstruction and momentum measurement by means of a computer program. The construction of this spectrometer is rather simple and there is no special technique and element for correction to aberration. It is suitable for usage of spectrometer with large solid angle and wide momentum range. The momentum resolution, momentum range and acceptance in our case are calculated by Monte Carlo simulation.更多还原
