Abstract：
A novel multi-cavity RF thermionic gun with very weak back bombardment effects has been designed, manufactured, tested, and subjected to experimentation. In this paper, we focus on the experimental results of this RF gun. From the current pulse shapes of BCT at the gun exit and the energy spectra at different positions of the macro-pulse, we can see that the back bombardment effects are suppressed greatly. A current of about 200 mA, a maximum electron energy of 1.8 MeV and a geometric RMS emittance of about 20-30 πrmm·mrad are obtained at the entrance of the linac.
