LINEAR INDUCTION ACCELERATORS ARE THE MEANS BY WHICH PULSED ELECTROSTATIC ACCELERATOR TECHNOLOGY CAN BE SCALED TO HIGH ENERGIES.

LINEAR INDUCTION ACCELERATORS ARE THE MEANS BY WHICH PULSED ELECTROSTATIC ACCELERATOR TECHNOLOGY CAN BE SCALED TO HIGH ENERGIES. WE PROPOSE STUDYING ION FOCUSING OF ELECTRONS IN LINEAR INDUCTION ACCELERATORS WITH GOALS OF REDUCING ACCELERATOR COMPLEXITY, COST AND SIZE, DECREASING BEAM EMITTANCE AND IMPROVING STABILITY TO TRANSVERSE DISRUPTIVE BEAM MODES. IN PHASE I RESEARCH, A SMALL INDUCTION LINAC WHICH UTILIZES ION FOCUSING WILL BE CONSTRUCTED. THIS DEVICE, DESIGNED FOR 8 STAGE, 40 KEV/STAGE, 1 KILOAMPERE OPERATION WITH 2, 20 NANOSECOND PULSES PER SECOND, WILL BE USED AS A TEST STAND FOR ION FOCUSING STUDIES. WE WILL PRODUCE A SPATIALLY DECREASING ION BACKGROUND FROM A PLASMA GUN AND STUDY THE EFFECTS OF BACKGROUND PROFILE ON BEAM TRANSPORT AND EMITTANCE. PHASE II RESEARCH WILL BE DIRECTED TOWARDS PERFECTING TECHNIQUES FOR PRODUCING LOW EMITTANCE ION FOCUSED BEAMS, ON A LARGER, MORE REALISTIC TEST STAND.
