RADLAC Technology Review

In this paper we review the technology development associated with the RADLAC program. A basic description of the pulsed transmission line approach for constructing high power electron linacs is given, and two examples, RADLAC I and RIIM, are described in some detail. Important problems associated with the design of the high current beam transport line are also discussed. Finally, we describe a recirculating linac concept based on the use of closed accelerating cavities and ionization channel beam transport.
