Abstract

In a recirculating linear accelerator system of the racetrack type the beam path consists of two shorter straight legs 12 and two longer straight legs 11 with four Pretzel beam-bending magnets 13 disposed one each at the corners of the beam path. The magnets may each bend the beam through 90 DEG , as shown, or through 84 DEG , in which case the two longer legs cross over one another (Figure 2, not shown). Two linear accelerators are disposed either as shown, or two in one leg (Figure 2). The beam is injected from a high voltage gun 20 via one of the magnets such that the axis of the injected beam lies at a tangent to the normal trajectory of a beam of similar energy in the magnet. The beam emerges by way of one of the magnets which is arranged in back-to-back double Pretzel configuration with a fifth Pretzel magnet 16. <IMAGE>
