Compact DC high-voltage photo-electron guns are able to meet the challenging demands of high-current applications such as energy-recovery linacs. A main design parameter for such sources is the electric field strength, which depends on the electrode geometry and is limited by the field-emission threshold of the electrode material. In order to minimize the maximum field strength for optimal gun operation, isogeometric analysis (IGA) can be used to exploit the axisymmetric geometry and describe… Expand
