Research on feasibility of closed and offset PCM focusing structures for sheet electron beams
关于闭合及偏置PCM结构约束带状电子注可行性的研究

Using theoretical analysis and numerical calculation, it has been demonstrated that the closed periodic cusped magnetic (PCM) field can effectively confine the sheet electron beam in two transverse directions simultaneously to realize the stable long distance transport, where the beam cross-section has an attainable shape of the state of the art. Moreover, the method for matching the transverse magnetic focusing force and the inner space charge force in the wide dimension of the sheet beam is given, which c...
