Claim 1
Independent Claim
85 words
MEANS FOR GENERATING MAGNETIC RADIATION IN THE MILLIMETER AND SUB-MILLIMETER RANGES, COMPRISING MEANS FOR GENERATING A UNIFORM FIRST MAGNETIC FIELD; MEANS ARRANGED IN SAID FIRST MAGNETIC FIELD FOR EMITTING AN ELECTRON STREAM OF SUBSTANTIAL INITIAL THICKNESS AT AN OBLIQUE ANGLE TO THE FIRST MAGNETIC FIELD; MEANS DEFINING A MICROWAVE CAVITY ARRANGED TO RECEIVE SAID ELECTRON STREAM; AND MEANS FOR GENERATING IN SAID MICROWAVE CAVITY AN INTENSE SECOND MAGNETIC FIELD APPLIED CONTEMPORANEOUSLY WITH SAID FIRST MAGNETIC FIELD TO REDUCE THE DIAMETRIC SIZE OF THE ELECTRON STREAM.
