COMPACT ACCELERATOR DESIGN BASED ON A CYCLIC INDUCTION ACCELERATOR WITH BRANCHED MAGNETICS

CURRENT DESIGNS FOR HIGH CURRENT (10-100KA) ACCELERATORS ARE BASED ON LINEAR OPERATING GRADIENTS OF AT BEST 1-2 MEV/METER. IN FERRI-(FERRO)MAGNETIC INDUCTION ACCELERATORS, THESE LOW GRADIENTS ARE IMPOSED BY THE PROPERTIES OF THE MATERIAL WHICH COMPRISES THE CORE. WITH AIR CORE RADIAL LINE INDUCTION LINACS, THE CONSTRAINTS IS DERIVED FROM THE GEOMETRY OF THE RADIAL LINES AND THE DIELECTRIC BREAKDOWN STRENGTH. SIGNIFICANT REDUCTIONS IN THE SIZE AND WEIGHT OF INDUCTION LINACS WILL HAVE A CONSIDERABLE IMPACT ON THE COST EFFECTIVENESS AND MILITARY UTILITY OF INDUCTION ACCELERATORS FOR CHARGED PARTICLE BEAM WEAPON (CPBW) APPLICATIONS. THE USE OF BRANCH MAGNETIC TECHNOLOGY MAY MAKE POSSIBLE THE DESIGN OF HIGH CURRENT RECIRCULATING INDUCTION LINACS WITH SIZE REDUCTIONS OF A FEW ORDERS OF MAGNITUDE. OUR GOAL WOULD BE TO DESIGN A PROOF-OF-PRINCIPLE EXPERIMENT OUTLINING DESIGNS FOR THE BRANCHED MAGNETIC PULSE POWER DEVICE. THIS INVESTIGATION WILLLEAD TO A TECHNICAL BASIS FOR THE ACCELERATOR GAP AND ELECTRON TRANSPORT SYSTEM DESIGN FOR A SPIRAL LINE RECIRCULATING LINAC.
