WT5”BZ]The design idea, the characteristic parameters and the beam dynamical result of a novel 4+1/2 cells microwave electron gun are presented in this paper.

With the development of free electron lasers (FELs), high brightness microwave electron gun is being paid more and more attention.

Upgrade design of a thermionic cathode RF gun;

Physical design of multicell thermionic RF gun with low back bombardment

Photo-cathode superconducting accelerator experiment system includes Nd:YAG mode-locked laser, Cs 2Te cathode, 2+1/2 RF gun, L band 3.

Using the mixture ambience of high pure hydrogen and high pure nitrogen as precursor,VO 2-x N y thin films with good thermal induced phase transition property were synthesized at low temperature by microwave plasma enhanced route using V 2O 5 as molecular precursors through coating film in glass slice.

Both conventional microwave and microwave plasma sintering technology have been involved to sinter ZnO based varistor.

The step sintering of microwave heating and microwave plasma heating (SSMP)was proposed in this paper.

45GHz microwave ion source s extraction system at the Institute of Heavy Ion Physics, Peking University.

Microwave coupling efficiency is an important parameter for microwave ion source, and has close relation with magnetic field strength and it s distribution.

And according to the demand of microwave ion source of intense neutron tube on magnetic field mode, we provided the design result and experiment data of multicusp field, double-magnet-ring field, field with transmiting magnet circuit, and makes .
