Apparatus for the iradiation of materials with a pulsed strip beam of electrons

Claim 1

APPARATUS FOR GENERATING A PULSATING STRIP PARTICLE BEAM FOR THE PURPOSE OF IRRADIATING MATTER COMPRISING A LONGITUDINAL PARTICLE EMITTER ADAPTED AND ARRANGED TO EMIT PARTICLES ALONG THE LONGITUDINAL EXTENT THEREOF, FOCUSING MEANS FOR FOCUSING THE PARTICLES EMITTED FROM SAID EMITTER INTO A STRIP BEAM EXTENDING THE ENTIRE LENGTH OF SAID EMITTER AND ACCELERATING MEANS FOR INTERMITTENTLY ACCELERATING PARTICLES EMITTED FROM SAID EMITTER, SAID ACCELEARTING MEANS INCLUDING AN ANODE, A HIGH VOLTAGE ALTERNATING CURRENT SOURCE, AND MEANS FOR COUPLDING SAID HIGH VOLTAGE SOURCE BETWEEN SAID ANODE AND EMITTER SO THAT PARTICLES ARE ACCELERATED FROM SAID EMITTER TOARDS SAID NOADE ONLY DURING THE HALF CYCLE OF SAID SOURCE WHEN THE ANODE VOLTAGE IS GREATER THAN THE EMITTER VOLTAGE, WHEREBY PARTICLES FROM SAID EMITTER ARE INTERMITTENTLY ACCELERATED TO A HIGH VELOCITY FOR IRRADIATION OF MATTER THE ACCELERATION OF SAID PARTICLES BEING LIMITED TO THE REGION OF SAID APPARATUS BETWEEN SAID PARTICLE EMITTER AND SAID ANODE.
