摘要：
The first emittance measurements with a new test injector facility (HOSTI) at GSI, designed for optimization of high current beam injection scheme, are discussed. The emittance of the ion beam (88 kV, Ar(1+) ions) was investigated as a function of various parameters related to the ion source, extraction, and postacceleration systems and the optimum parameters for future low energy beam transport line are concluded. The preliminary results of the emittance measurements with superconducting solenoid are presented. The influence of the focusing strength as well as the longitudinal field shape of the solenoid on the beam emittance is described.
