Abstract
A traveling-wave tube having a cylindrical vacuum envelope surrounded by a permanent-magnet system of ring-shaped pole washers and magnet rings respectively disposed therebetween and having opposite polarizations alternatingly in axial direction, which includes spacer rings formed of nonmetallic material surrounding the cylindrical vacuum envelope and spacing the magnet rings therefrom, corresponding magnet rings and spacer rings being soldered together into respective strong and stable units.
Claims2
Traveling-wave tube having a cylindrical vacuum envelope surrounded by a permanent-magnet system of ring-shaped pole washers and magnet rings respectively disposed therebetween and having opposite polarizations alternatingly in axial direction, comprising spacer rings formed of nonmagnetic material surrounding the cylindrical vacuum envelope and spacing the magnet rings therefrom, corresponding magnet rings and spacer rings being soldered together into respective strong and stable units and respective heat removing washers disposed between adjacent pairs of the pole washers.
