Class Information
Number: 315/3.5
Name: Electric lamp and discharge devices: systems > Cathode ray tube circuits > Combined cathode ray tube and circuit element structure > Traveling wave tube with delay-type transmission line
Description: Subject matter in which a transmission line or device arranged to propagate a traveling electromagnetic wave is constructed and arranged to have a wave component the velocity of which is reduced in comparison to the wave velocity in free space; and in conjunction therewith are means for generating an electron beam whose path is in such proximity to the path of said traveling wave component as to permit an exchange of energy between such beam and the traveling wave propagated along the transmission path.
