A DEVICE FOR PRODUCING HIGH DENSITY ELECTRON STREAMS WHICH COMPRISES A CYLINDRICAL ENVELOPE HAVING A LONGITUDINAL AXIS, A CATHODE POSITIONED AT ONE END OF SAID ENVELOPE ABOUT THE AXIS, AN ANODE SPACED LINEARLY A SHORT DISTANCE FROM SAID CATHODE ALONG THE AXIS, AN AXIALLY ALIGNED APERTURE THROUGH SAID ANODE, SAID CATHODE AND ANODE ADAPTED TO PROVIDE A FLOW OF ELECTRONS EMITTED BY SAID CATHODE THROUGH SAID APERTURE ALONG THE AXIS OF SAID ENVELOPE, AN ELECTRODE POSITIONED OUTWARDLY OF SAID CATHODE ABOUT THE AXIS OF SAID ENVELOPE AND EXTENDING TOWARD SAID ANODE ABOUT THE SPACE BETWEEN SAID CATHODE AND SAID ANODE, SAID ELECTRODE ADAPTED TO SAID IN COLLIMATING ELECTRONS EMITTED BY SAID CATHODE AND DIRECTING SAID ELECTRONS THROUGH SAID APERTURE IN SAID ANODE, A PLURALITY OF AXIALLY ALIGNED ELECTRODES SPACED ALONG THE AXIS OF SAID ENVELOPE DOWNSTREAM FROM SAID CATHODE AND ANODE, SAID ELECTRODES ADAPTED TO COLLECT ELECTRONS DETACHED FROM SAID ELECTRON STREAM, AND AN INLET AT ONE END OF SAID ENVELOPE AND AN OUTLET IN THE OPPOSITE END THEREOF FOR PERMITTING A FLOW OF IONIZABLE GAS THROUGH SAID ENVELOPE ALONG SAID ELECTRODES, ANODE AND CATHODE.
