【摘要】 研究了新型钡钨阴极发射性能,并且分别用扫描电子显微镜(SEM)和工业CT微焦点系统来分析所研制的新型钡钨阴极的表面形貌和内部微细结构。该阴极不仅简化了传统浸渍钡钨阴极生产工艺,而且发射性能要优于传统工艺阴极。更多还原

【Abstract】 We studied the emitting performance of high current cathode, and analysed its surface and inner micro structures by the industrial computer tomography (ICT) and SEM. This new cathode can simplify the traditional manufacture procedure of the cathode, and its emitting performauce is also more better than the traditional cathodes.更多还原
