Description
A novel multi-cavity RF thermionic gun with much less back bombardment effect has been designed, built, tested and experimented. From the pulse shapes 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 α-magnet is 200 mA, and electron energy is about 1.8 MeV. The geometric RMS emittance is less than 28π·mm·mrad in x-direction, and less than 22π·mm·mrad in y-direction at the linac entrance
