In this work, the radiation environment in the target area of a fragment separator is evaluated using FLUKA code. The energy deposition in quadrupole coils is presented to provide guidance for a radiation-resistant magnets design. Results show that neutrons dominate in the prompt radiation field. A compact shielding design is recommended for high radiation areas along with the minimization of air activation in the tunnel in order to minimize the radiation effect on nearby beam lines. The…

Radiation protection, radiation safety and radiation shielding assessment of HIE-ISOLDE.
TLDR
The state-of-the-art Monte Carlo particle transport simulation program FLUKA was used to perform the computation of the ambient dose equivalent rate distribution and of the particle fluxes in the projected HIE-ISOLDE facility (taking into account the upgrade nominal primary proton beam energy and intensity) and the shielding assessment of the facility.

TLDR
The production of radioactive ions by using direct in-flight separation techniques is discussed, and the relative advantages and disadvantages of the method are discussed along with techniques that can be used to overcome some of the disadvantages.
