摘要
Abstract
To meet the evaluation requirements of magnetic fields for high-power devices,the design and manufacturing of an electron fluorescence imaging tube have been completed.The device consists of a thermionic cathode electron gun,an electron beam drift tube,and a fluorescent screen.Under ideal uniform magnetic field conditions,the annular electron beam generated by thermionic cathode emission strikes the fluorescent screen at the right end,forming a clearly visible circular light spot.Its primary function involves detec-ting magnetic field axis alignment during calibration(actual operational state).When non-ideal magnetic fields cause electron beam de-flection,an eccentric light spot appears on the fluorescent screen.By observing the shape and position of the light spot,operators can ad-just the axis position of the superconducting magnet to identify the optimal magnetic axis alignment.关键词
