Claim 1
Independent Claim
179 words
A GROWING WAVE TUBE FOR OPERATION AT A GIVEN FREQUENCY COMPRISING: (A) MEANS FOR PRODUCING AN ELECTRON SPACE CHARGE IN A GIVEN REGION; (B) MEANS FOR ESTABLISHING A MAGNETIC FIELD IN A GIVEN DIRECTION IN SAID REGION; (C) MEANS FOR COUPLING A FAST WAVE TRANSMISSION LINE TO THE SPACE CHARGE IN A FIRST PORTION OF SAID REGION TO EXCITE A FAST CYCLOTRON WAVE ON SAID SPACE CHARGE PARALLEL TO SAID MAGNETIC FIELD; (D) THE INTENSITY OF SAID MAGNETIC FIELD IN SAID PORTION BEING SUCH THAT THE PHASE VELOCITY OF SAID FAST CYCLOTRON WAVE THEREIN IS SUBSTANTIALLY EQUAL TO THE PHASE VELOCITY OF WAVES ALONG SAID COUPLING MEANS AT SAID GIVEN FREQUENCY; AND (E) MEANS FOR PROJECTING A STREAM OF ELECTRONS THROUGH AT LEAST A SECOND PORTION OF SAID REGION IN A DIRECTION SUBSTANTIALLY PARALLEL TO SAID GIVEN DIRECTIONS; (F) THE PHASE VELOCITY OF SAID FAST CYCLOTRON WAVE HAVING A VALUE IN SAID SECOND PORTION SUBSTANTIALLY EQUAL TO THE PHASE VELOCITY OF A SLOW WAVE ON SAID STREAM AT SAID GIVEN FREQUENCY, FOR GROWING WAVE INTERACTION WITH SAID SLOW WAVE.
