The SISSI project: an intense secondary ion source using superconducting solenoid lenses

Technical Report:

Abstract

Secondary beams are routinely produced at GANIL for experiments from a target placed in the high energy beam line of the accelerator. In order to make a better use of the higher beam intensities soon available at GANIL, a proposal called SISSI was presented in 1989. This project is now funded. It consists of a set of two superconducting solenoid lenses of very short focal length (.6m). The first solenoid is used to sharply focus the incoming beam on a fast moving target. The second increases the angular acceptance of the beam line downstream the target for charged reaction products. Calculations show that from .4mm diameter beam spot on the target, an acceptance angle of up to 80 mrad will be reached without significant emittance growth due to aberration effects. Technical aspects of that project are then presented concerning both the solenoids and the cryogenic devices as well as the solid target.
