Linear induction accelerators with magnetic elements

A new class of linear induction accelerators with magnetic elements used as the sources of electron beams for relativistic high-power microwave genera tors is presented [1, 2]. Such accelerators have been under development at the Nuclear Physics Institute of Tomsk Polytechnical University (NPI TPU) s ince the 1990s on the basis of an original configuration with the use of lo w-impedance strip forming limes laid over the induction system as an Archim ed helix [4]. By now, the designed accelerators have electron energies of 0 .4-2.4 Mev at currents of 2-6 kA and pulse repetition rates of up to 400 Hz in the continuous operation mode and up to 3.3 kHz in the pulse-burst mode .
