Desgin Studies on High Current and Grid Control Electron Gun
2011
Electron gun,the source of electrons,is a kind of ultrahigh vacuum device and plays an important role in different kind of accelerators.With the irradiation accelerator demands,decribes the design studies on beam optics opitimization.The simulation result shows that the beam current is above 5 A with cathode voltage of 80 kV and beam emittance,gun electric field and beam waist radius meet the accelerator needs.The electron gun manufactured and installed in the test stand,the conditioning and test will be done in the near future.
