The Current Status of the LLNL Recirculator
Abstract
The Heavy Ion Fusion Group at Lawrence Livermore National Laboratory has for several years been developing the world’s first circular induction accelerator designed for space charge dominated ion beams. Currently, the machine extends to 90 degrees, or 10 half-lattice periods (HLP) with induction cores for acceleration placed on every other HLP. Beam acceleration using an inductive adder circuit to pulse the induction cores was recently achieved with no adverse effects on the beam quality. In addition, a pulser to ramp the dipole plates was also implemented. The effect of these two systems can be clearly seen by changes in transverse charge centroid positions as measured by the Capacitve Beam Probes. Data from this system and other diagnostics will be presented.
