The Gamma Factory (GF) initiative proposes to use partially stripped ion (PSI) beams as drivers of a new type of high-intensity and high-energy (0.1–400 MeV) photon source. As part of the ongoing Physics Beyond Collider studies, initial beam tests were carried out in 2017 and 2018 at the SPS and LHC with partially stripped xenon and lead beams [...]

Further development of GALS setup at JINR
/ Zemlyanoy, Sergey (Dubna, JINR) ; Avvakumov, Konstantin (Dubna, JINR) ; Zuzaan, Batsuren (Dubna, JINR) ; Kudryavtsev, Yury (Leuven U.) ; Fedosseev, Valentine (CERN) ; Bark, Robert (Pretoria, Natl. Res. Inst. Math.) ; Janas, Zenon (Warsaw U.)
The aim of this paper is to report on the present status of the GAs cell based Laser ionization and separation Setup (GALS project) that is under construction at the Flerov Laboratory of Nuclear Reactions (FLNR) of JINR, Dubna. This project is directed on production of neutron-rich isotopes in the region of the magic $N$ = 126 neutron number using multi-nucleon transfer reactions. [...]

MELISSA: Laser ion source setup at CERN-MEDICIS facility. Blueprint
/ Gadelshin, Vadim (Johannes Gutenberg Universitaet Mainz (DE)) ; Barozier, Vincent (CERN) ; Cocolios, Thomas Elias (KU Leuven (BE)) ; Fedosseev, Valentine (CERN) ; Formento Cavaier, Roberto (Centre National de la Recherche Scientifique (FR)) ; Haddad, Ferid (CERN) ; Marsh, Bruce (CERN) ; Marzari, Stefano (CERN) ; Rothe, Sebastian (CERN) ; Stora, Thierry (CERN) et al.
The Resonance Ionization Laser Ion Source (RILIS) has become an essential feature of many radioactive ion beam facilities worldwide since it offers an unmatched combination of efficiency and selectivity in the production of ion beams of many different chemical elements. In 2019, the laser ion source setup MELISSA is going to be established at the CERN-MEDICIS facility, based on the experience of the workgroup LARISSA of the University Mainz and CERN ISOLDE RILIS team.

A number of radiogenically produced dysprosium isotopes have been studied by in-source laser spectroscopy at ISOLDE using the Resonance Ionization Laser Ion Source (RILIS). Isotope shifts were measured relative to $^{152}$Dy in the 4 f$^{ 10}$6s$^{2}$ $^5$I$_8$ (gs) $\rightarrow$ 4 f$^{ 10}$6s6p (8,1)$^8_o$ (418.8 nm$_{vac}$) resonance transition. [...]

Laser photodetachment of radioactive ions: towards the determination of the electronegativity of astatine
Reference: Poster-2017-585
Created: 2017. -1 p
Creator(s): Rothe, Sebastian; Sundberg, Julia; Welander, Jakob Emanuel; Chrysalidis, Katerina; Day Goodacre, Thomas [...]
Negatively charged ions are mainly stabilized through the electron correlation effect. A measure of the stability of a negative ion is the electron affinity, which the energy gain by attaching an electron to a neutral atom. This fundamental quantity is, due to the almost general lack of bound excited states, the only atomic property that can be determined with high accuracy for negative ions. We will present the results of the first laser photodetachment studies of radioactive negative ions at CERN-ISOLDE. The photodetachment threshold for the radiogenic iodine isotope 128I was measured successfully, demonstrating the performance of the upgraded GANDALPH experimental beam line. The first detection of photo-detached astatine atoms marks a milestone towards the determination of the EA of this radioactive element.
