Abstract：
A novel multi-cavity RF thermionic gun with much less back bombardment effect has beea designed, built, tested and experiraeated. ln this paper we mainly discuss the expermental results of this RF gun From the pulse shapea of BCT at the gun exit and energy spectra at different. positions of the pulse, we have seen that the back bombardment power is much less than the single cavity RF gun. The current after the a-magnet is 200mA, and electron energy is about 1.8MeV. The geometric RMS emitttance is less than 28π nm . mradia x-direction, and lessthan 22π·mm·mrad in y-direction at the linac entrance.
