Abstract

The conceptual design of the injection linac of the Brazilian National Laboratory for Synchrotron Light (LNLS) is described. The design of the LNLS linac is based primarily on the Stanford Two-Mile Linear Accelerator for reliability reasons. The frequency, mode, and type of structure are chosen to be the same as those of the Stanford accelerator. An electrostatic gun provides 80-keV electrons which will be further accelerated to 100 MeV in four 3-m-long accelerating sections. A preliminary study shows that the required beam current and energy dispersion at the end of the linac can be reached with just a prebuncher, without using a buncher. Focusing of the beam is accomplished by three magnetic lenses and a solenoid in the low-energy region and by triplets between the accelerating structures in the high-energy region
