Abstract
The thermodynamics of the electron gun are investigated for the W-band Sheet beam klystron using ANSYS. With the heater temperature at 1050degC, the stable and uniform temperature distributions are achieved for the designed non-axisymmetric structures of sheet beam electron gun. Furthermore, the axis thermal deformation of the cathode is 0.491 mm, and the focus electrode is 0.594 mm with the thermal expansion, which is much larger than that of cylindrical beam electron gun in TWT.
