[en] The ISL White Paper (WP) offers many options in the choice of primary and secondary accelerators, and existing facilities (such as ISIS, PSI, LAMPF, TRIUMF. ATLAS, ISOLDE, and Louvain) can serve as models in selecting a configuration. With the Benchmark Facility of the WP as a starting point, the ISL concept has now been expanded in several ways. Three target stations are desired to ensure uninterrupted RNB delivery and the use of a variety of targets and ion source: (1) The first target station could be dedicated to conventional targets and ion sources similar to those used at ISOLDE. (2) The second station could house both laser- and surface ion sources because they are mechanically similar. (3) The third station could be designed specifically for targets coupled to ECR sources. In addition, two separators are foreseen: (1) a general-purpose separator (GPS) for the ECR source operating at a constant E/μ of 10 keV/μ and (2) a high-resolution separator (HRS) for the first two stations operating with a constant ion energy of ∼100 keV. The first RFQ would only be needed for the HRS branch to boost the energy from 1 or 2 keV/μ to ∼10 keV/μ
