WIDE-BAND HIGH-POWER DELAY LINE

In a delay line of an electron tube for amplifying or generating microwaves, externally of and parallel to a main conductor helix within which an electron beam travels axially, there extends a secondary helix which has a pitch and a diameter half the size of those of the main helix and which is so a...

Summary:In a delay line of an electron tube for amplifying or generating microwaves, externally of and parallel to a main conductor helix within which an electron beam travels axially, there extends a secondary helix which has a pitch and a diameter half the size of those of the main helix and which is so arranged that its turns electrically contact those of the main helix at several locations along a generatrix common to both helices. The field effect generated by the secondary helix substantially diminishes parasitic phenomena that appear in a delay line having a main helix of large diameter.
