Abstract :
A scaled test of a final focus lattice for heavy ion fusion (HIF) is planned at LBNL. The test parameters have been set by scaling the length dimensions of the envelope equation by one tenth while maintaining the generalized perveance. The values to be scaled were taken, in large part, to be those of the HIBALL-II final focus system. The tenth-scale test will focus a 120 keV Cs+ beam to a radial spot size of 0.25 mm. Tracking studies of the tenth-scale system have been performed using a version of COSY INFINITY modified to include a linear space charge force. A description of the planned experimental system, the beam parameters, and simulation results are presented
