註釋

The results of the experiment have been used to inform the design of a Cherenkov Maser which couples a TM0 ,6 volume field with a HE16,1 surface field on a 20 mm diameter 2D PSL structure with 20 longitudinal corrugations of period 3.2 mm and 16 azimuthal variations of peak to peak amplitude of 1 mm. The beam-wave interaction in the 20 mm inner diameter 2D PSL was modelled using the particle in cell code Magic 3D. In the simulations an axial magnetic field of 6 T was used to guide a 1.6 kA, 300 kV annular electron beam with a mean radius of 8.5 mm and beam thickness of 1 mm through the 2D PSL where the beam was located 0.5 mm away from the inner diameter of the 2DPSL. Numerical simulations predict excitation of the 2D PSL by this electron beam will generate 150MW of power at an operating frequency of 97 GHz corresponding to an electronic efficiency of 30 %.
