    Influence of the injected beam parameters on the capture efficiency of an electron cyclotron resonance based charge breeder by A. Galatà, D. Mascali, G. Torrisi, L. Neri, L. Celona, J. Angot

    Published 2017-06-01
    “…Electron cyclotron resonance ion sources based charge breeders (ECR-CB) are fundamental devices for Isotope Separation On Line (ISOL) facilities aiming at postaccelerating radioactive ion beams (RIBs). Presently, low intensity RIBs do not allow a conventional tuning of the ECR-CB: as a consequence, it has to be set with a stable 1+ pilot beam first, switching then to the radioactive one without changing any parameter; this procedure is usually called “blind tuning.” …”

    Published 2021-03-01
    “…Abstract We report on ion irradiation experiments performed on compounds belonging to the $$\hbox {BaFe}_2\hbox {As}_2$$ BaFe 2 As 2 family, each one involving the partial substitution of an atom of the parent compound (K for Ba, Co for Fe, and P for As), with an optimal composition to maximize the superconducting critical temperature $$T_c$$ T c . Employed ion beams were 3.5-MeV protons, 250-MeV Au ions, and 1.2-GeV Pb ions, but additional data from literature are also considered, thus covering a wide range of ions and energies. …”

    Heavy-ion production of 77Br and 76Br by Sean R. McGuinness, John T. Wilkinson, Graham F. Peaslee

    Published 2021-08-01
    “…A promising alternative method using heavy-ion fusion-evaporation reactions for the production of the medically relevant bromine radioisotopes 76Br (t1/2 = 16.2 h) and 77Br (t1/2 = 57.0 h) is presented. Heavy-ion beams of 28Si and 16O were used to bombard natural chromium and copper targets just above the Coulomb barrier at the University of Notre Dame's Nuclear Science Laboratory to produce these bromine and precursor radioisotopes by fusion-evaporation reactions. …”
