  • The thermal statement of the helical slow wave structure is analyzed in detail in this paper, and an elliptical shell is firstly brought up to replace the conventional circle shell in the slow-wave structure. Then the 3D thermal analysis of the helical slow structure with elliptical shell is done with the help of ANSYS and the high-frequency characteristics simulation is also done with WMS CST. It is demonstrated that the ability of heat transfer of the helical slow structure with elliptical shell is much better than the conventional one and the more the support rods are, the better the heat transfer is. It is also found that the bandwidth of the elliptical shell is more wider than the circle one while the coupling impedance just decrease a little.
