The DEMATRON—A new crossed-field amplifier

Crossed-Field Microwave Devices

“…(The SWS gets excited on account of beam modulation after moving across the lossy portion in a TWT and thus virtually, the hot RF loss is negligible even though the return loss along the helix on account of any reflected wave from the inputjoutut terminals is very high.) By splitting the overall delay line in two sections and introducing a sever in between the two sections, it has been possible to increase the gain of a CF A upto about 25 dB (Pokorney et al 1962). The sever provides an isolation between the two sections and the cold coupling between the two sections is only through leakage of RF field.…”

“…This was believed to be a reasonable voltage for a tube to be utilized at an element or subarray level. (1) where K is tl[ie interaction impedance for the n space harmonic 3 is tike phase constant for the n space harmonic P is the total RF power flow in the slow-wave structure E is the longitudinal electric field strength at the surface of the slow-Wc^ve structure for the n space harmonic.…”
