T1 TRANSITION RADIATION OF MODULATED ELECTRON BEAM TRAVERSING THE WIRE SHIELD JF Telecommunications and Radio Engineering JO TRE YR 2011 FD 2011-03-17 VO 70 IS 4 SP 353 OP 366 K1 modulated electron stream K1 electron bunches K1 wire screen K1 transition radiation K1 energy flux density AB The transition radiation of an electron beam traversing the wire shield has been investigated theoretically. The electron beam has the form of the periodical series of discrete bunches and moves along the normal to the shield. Every bunch by itself has the form of the charged-filament segment directed normal to the beam velocity. The wire shield is located in vacuum and has the form of a one-dimensional array of parallel metal wires. Two different mutual arrangements of bunches and wires, namely, the perpendicular and the parallel arrangements have been considered. The spectral energy density, the directional diagram, and the numerical estimations of the radiation power have been obtained. It has been demonstrated that the transition radiation is the series of harmonics. The harmonic frequencies are multiple of the reverse spatial period of the modulated beam. The directional diagram has maximum along the wires for the non-relativistic coherent bunches.
