MEQALAC: A NEW APPROACH TO LOW BETA ACCELERATION

摘要

An acceleration system is described which allows one to accelerate high currents of ions at very low velocities. The main principle is to utilize an array of electrostatic quadrupoles in an rf linac drift tube, rather than a single magnetic quadrupole, as is usually the case. Because electrostatic quads can be built with very small apertures, relatively high frequencies can be used. A number of examples are given.
