Generation and control of charged particle beams using induction accelerators

Investigations have been carried out into the use of Induction Linacs for the acceleration of proton beams. A 1.5 MeV, 2 kA, 50 nsec beam has been generated using an inductively fed magnetically insulated diode. Results will be reported on propagation with and without collective focusing of the beam. A program to study autoacceleration techniques for the production and time compression of high energy beams has been started recently. A ferrite loaded cavity was used to couple energy from the beam to a 70 ohm transmission line and, after a predetermined delay, back to the beam. Initial experimental results demonstrating particle acceleration and pulse compression will be presented.
