A Wide-Range Magnetic Spectrometer For Electron Scattering In Medium Energy Range

Abstract：

A non-focusing magnetic spectrometer designed 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 through a computer program. The structure of this spectrometer is rather simple and no special technique and element are required for the correction to aberration. It is suitable for the usage of a spectrometer with a large solid angle and wide momentum range. The momentum resolution, momentum range, and acceptance in our case are calculated by Monte Cario simulation.
