摘要：

We report on the optimization of the gas jet system employed to couple the TRIGA-SPEC experiment to the research reactor TRIGA Mainz. CdI2 aerosol particles suspended in N-2 as carrier gas are used for an effective transport of fission products from neutron induced U-235 fission from the target chamber to a surface ion source. Operating conditions of the gas jet were modified to enable the implementation of an aerodynamic lens, fitting into the limited space available in front of the ion source. The lens boosts the gas jet efficiency by a factor of 4-10. The characterization of the gas jet system as well as the design of the aerodynamic lens and efficiency studies are presented and discussed. (C) 2015 Elsevier B.V. All rights reserved.
