High intensity production of high and medium charge state uranium and other heavy ion beams \nwith VENUS

Abstract

The next generation, superconducting ECR ion source VENUS (Versatile ECR ion source for NUclear Science) started operation with 28 GHz microwave heating in 2004. Since then it has produced world record ion beam intensities. For example, 2850 e mu A of O6+, 200 e mu A of U33+ or U34+, and in respect to high charge state ions, 1 e mu A of Ar18+, 270 e mu A of Ar16+, 28 e mu A of Xe35+ and 4.9 e mu A of U47+ have been produced. A brief overview of the latest developments leading to these record intensities is given and the production of high intensity uranium beams is discussed in more detail.
