16. Interaction of atomic ions with electrons : Recombination rate coefficients for C1+, F5+, Ne5+, S14+,S15+
Abstract : This thesis concentrates on electron-ion interaction studies, in particular focusing on dielectronic recombination (DR) of highly charged ions relevant to astrophysics and plasma physics. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. READ MORE

17. Ions in cold electrostatic storage devices
Abstract : We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. READ MORE

18. Charge Breeding and Production of Multiply Charged Ions in EBIS and ECRIS
Abstract : The REXEBIS is an Electron Beam Ion Source (EBIS) developed for charge breeding of the exotic and sometimes short-lived isotopes that are produced at ISOLDE for the REX-ISOLDE post accelerator. Bunches of singly charged radioactive ions are injected into the EBIS and charge bred to a charge-to-mass ratio of approximately ¼, and thereafter extracted and injected into a short 3-stage LINAC for acceleration to a few MeV/u.

20. Electron transfer in slow collisions of highly charged ions with atoms and molecules
Abstract : Several spectroscopic methods have been used to study single- and double electron transfer in slow collisions between highly charged ions with neutral atoms and the C60 molecule.Radiative and non-radiative decay from high-lying doubly-excited states, populated in slow (v = 0.40 a.u.
