Controlled electron buncher

Claim 1

A VACUUM TUBE DEVICE FOR FORMING, ISOLATING, AND ACCELERATING CONTROLLED ELECTRON BUNCHES, COMPRISING: AN ELECTRON SOURCE; AN ELECTRON POST-ACCELERATOR HAVING A HIGH POSITIVE POTENTIAL, WITH RESPECT TO SAID SOURCE, WHICH IS SUITABLE TO ACCELERATE ELECTRONS TO A DESIRED TRANSLATIONAL ENERGY; AN ELECTRON TRAPPING REGION DISPOSED BETWEEN SAID SOURCE AND ACCELERATOR, SAID TRAPPING REGION INCLUDING A PINCH-OFF PORTION PROXIMATE SAID SOURCE, A STORAGE PORTION MIDWAY THEREALONG, AND A BARRIER PORTION PROXIMATE SAID ACCELERATOR; MEANS FOR APPLYING A POTENTIAL DISTRIBUTION ALONG SAID TRAPPING REGION WHICH HAS, IN RESPECT TO SAID STORAGE PORTION, A NEGATIVE POTENTIAL DIFFERENCE FROM TION AND A CONTINUALLY INCREASING POTENTIAL DIFFERENCE FROM SAID SOURCE, SAID DISTRIBUTION, RESPECTIVELY, PREVENTING ELECTRONS ENTERING THEREIN FROM ADVANCING AND RETURNING TO SAID ACCELERATOR AND SOURCE, THEREBY FORMING AN ELECTRON BUNCH THEREIN; MEANS TO APPLY A PULSE AT SAID PINCH-OFF PORTION, SAID PULSE ESTABLISHING A NEGATIVE POTENTIAL WITH RESPECT TO SAID SOURCE FOR AN INSTANTANEOUS ISOLATION THEREFROM OF SAID ELECTRON BUNCH; MEANS TO APPLY A NEGATIVE DUMPING PULSE AT SAID STORGE PORTION SUBSEQUENT TO SAID ISOLATION; AND MEANS TO APPLY A POSITIVE PULSE AT SAID BARRIER PORTION SIMULTANEOUSLY WITH SAID DUMPING PULSE THEREBY CHANGING SAID POTENTIAL DISTRIBUTION ALONG SAID TRAPPING REGION TO FORCE SAID ELECTRON BUNCH TOWARD SAID POSTACCELERATOR FOR ACCELERATION THEREFROM PRODUCING A PULSED OUTPUT.
