The ISOLDE experiment at CERN aims to study the structure and dynamics of radioactive nuclei and their applications. The high-energy scientific program developed with the HIE-ISOLDE post-accelerator requires a high-resolution equipment to analyze the reaction fragments. The Spectrometer described in the Letter of Intent LoI-INTC-I-228 aiming to developing a detailed design study of the so-called “ISOLDE Superconducting Recoil Separator” (ISRS) was approved in 2021 by the ISOLDE and Neutron Time-of-Flight Experiments Committee (INTC) of CERN.
