Current status of In-flight fragment separator for RAON

Abstract

The in-flight fragment (IF) separator of RAON, the main device for producing rare isotope (RI) beams for nuclear science research and applications, is under development. The IF separator consists of a target, beam dump, magnets, and detector systems. The high-power target and beam dump for the 80 kW primary beam were fabricated using graphite. The IF magnet system consists of a total of 8 dipole magnets, 15 sets of quadrupole magnet triplet, 2 sextupole magnets, and power supply systems. In the high radiation region near the target and beam dump, warm iron high temperature superconducting (HTS) magnets and radiation-resistive dipole magnet are used. In the other region, cold iron low temperature superconducting (LTS) quadrupole magnet triplets and normal conducting (NC) dipole and sextupole magnets are used. Fabrication of all IF magnets have been completed and on-site installation is in progress. Also, detectors for particle identification (PID) and data acquisition (DAQ) systems are currently being installed at the focal planes of the IF separator. The current status of IF separator is briefly introduced.
