The problem of the radiation in penetrations was solved in the MARS sloshing beam line by providing several bends through the penetration shield to efficiently attenuate the streaming radiation. The design of the shield within the NBI penetration and the off-axis arrangement of the ion sources along with the selection of low activation materials for the NBI help reduce the biological dose to an acceptable level at the back of the injector where hands-on maintenance is highly desirable.
