Abstract

We consider possible configurations for injection of photocathode-produced electron beams straight into linear accelerating sections. A slightly convergent beam into the linac is required for maximum transmission through the linac sections and therefore a solenoid pair is considered. We describe strategies for placing the rf gun injector and the strength of the solenoids so as to minimize the emittance growth of the beam as it traverses the linac sections. The simulation codes PARMELA and TRACE 3-D were used for this design study
