Beam collector structure for electron tubes having concentric longitudinally partitioned cooling annuli

Claim 1

AN ELECTRON DISCHARGE DEVICE COMPRISING MEANS FOR FORMING A BEAM OF ELECTRONS; MEANS FOR COLLECTING THE BEAM OF ELECTRONS; ELECTROMAGNETIC WAVE SUPPORTING STRUCTURE ARRANGED ALONG A BEAM PATH DEFINED BETWEEN SAID BEAM FORMING AND COLLECTING MEANS FOR ELECTROMAGNETIC INTERACTION WITH THE BEAM OF ELECTRONS PASSABLE THERETHROUGH; MEANS FOR EXTRACTING R.F. ENERGY FROM THE DEVICE; SAID MEANS FOR COLLECTING THE BEAM OF ELECTRONS COMPRISING A TUBULAR COLLECTOR FOR RECEIVING THE BEAM INCIDENT THEREIN, A PLURALITY OF LONGITUDINALLY DIRECTED COLLECTOR FINS ON THE OUTER SURFACE OF SAID COLLECTOR DEFINED BY A PLURALITY OF PERIPHERALLY SPACED-APART LONGITUDINALLY DIRECTED COLLECTOR CHANNELS, A TUBULAR BAFFLE SURROUNDING SAID COLLECTOR FINS WHEREBY SAID COLLECTOR FINS AND SAID BAFFLE DEFINE AN INTERIOR, LONGITUDINALLY PARTITIONED ANNULUS, SAID TUBULAR BAFFLE MEMBER HAVING A PLURALITY OF LONGITUDINALLY DIRECTED BAFFLE FINS, DEFINED BY A PLURALITY OF PERIPHERALLY SPACED-APART LONGITUDINALLY DIRECTED BAFFLE CHANNELS ON THE EXTERIOR SURFACE OF SAID TUBULAR BAFFLE, A TUBULAR OUTER JACKET SURROUNDING SAID BAFFLE WHEREBY SAID BAFFLE FINS AND SAID TUBULAR OUTER JACKET DEFINE AN EXTERIOR LONGITUDINALLY PARTITIONED ANNULUS, MEANS FOR CONNECTING SAID INTERIOR AND EXTERIOR COOLING ANNULUS, AND MEANS COMMUNICATING WITH SAID INTERIOR AND EXTERIOR ANNULUS FOR DISTRIBUTING AN INPUT AND OUTPUT FLOW OF LIQUID COOLANT THERETHROUGH TO REMOVE HEAT DISSIPATED IN SAID COLLECTOR BY THE BEAM OF ELECTRONS.
