DESIGN OF COMPONENTS FOR AN AMPERE INTENSITY, MEV ENERGY, DC ELECTRON BEAM SYSTEM

NATIONAL ELECTROSTATICS CORPORATION (NEC) PROPOSES TO DESIGNCRITICAL COMPONENTS, AND INVESTIGATE REQUIRED ION OPTICAL ELEMENTS FOR A 3 MEV, 2-5 AMP DC ELECTRON BEAM. SUCH A SYSTEM WOULD BE BASED ON A VERTICAL TEST PELLETRON ACCELERATOR OF THE VAN DE GRAAFF TYPE OWNED AND OPERATED BY NEC. IN THIS CONCEPT AN ELECTRON BEAM PRODUCED IN THE HIGH VOLTAGE TERMINAL OF THE PELLETRON ACCELERATOR WILL BE ACCELERATED DOWNWARDS TO GROUND POTENTIAL, FOCUSED AND DEFLECTED 180 DEGREES UPWARDS, DECELERATED AND COLLECTED IN THE HIGH VOLTAGE TERMINAL. THE OBJECTIVE IS TO PRODUCE A DESIGN FOR CRITICAL COMPONENTS OF A HIGH CURRENT, GOOD EMITTANCE ELECTRON BEAM WHICH CAN BE TRANSMITTED THROUGH A SERIES OF MAGNETIC DEFLECTIONS AND DECELERATED TO NEAR ZERO ENERGY WITH A LOSS OF ELECTRONS OF LESS THAN OR EQUAL TO 1 IN 10(4) AND A TOTAL ACCELERATOR POWER DISSIPATION OF 25 HP OR LESS. ALL EFFORTS WOULD BE COORDINATED AND OPENLY DISCUSSED WITH FREDRICK E. MILLS OF THE UNIVERSITY OF WISCONSIN-MADISON (UW-MADISON) AND FERMI NATIONAL ACCELERATOR LABORATORY (FERMILAB), AND DAVID B. CLINE OF THEUW-MADISON, WHO ARE CURRENTLY HEADING AN EFFORT FUNDED BY DOE TO INVESTIGATE HIGH QUALITY DC ELECTRON BEAMS FOR POSSIBLE USE AS PART OF AN ANTIPROTON PHASE SPACE COOLING DEVICE AT FERMILAB.
