“…At the Leuven Isotope Separator On Line facility (Belgium), beams of short-lived radioactive isotopes are produced using resonant laser ionization in a buffer gas cell [118]. This technique allows for the production of short-lived purified radioactive beams from elements that are, due to their physico-chemical properties, not available from thick target ion source systems like ISOLDE.…”

Abstract. The Miniball germanium detector array has been operational at the REX (Radioactive ion beam EXperiment) post accelerator at the Isotope Separator On-Line facility ISOLDE at CERN since 2001. During the last decade, a series of successful Coulomb excitation and transfer reaction studies have been performed with this array, utilizing the unique and high-quality radioactive ion beams which are available at ISOLDE. In this article, an overview is given of the technical details of the full Miniball setup, including a description of the γ-ray and particle detectors, beam monitoring devices and methods to deal with beam contamination. The specific timing properties of the REX-ISOLDE facility are highlighted to indicate the sensitivity that can be achieved with the full Miniball setup. The article is finalized with a summary of some physics highlights at REX-ISOLDE and the utilization of the Miniball germanium detectors at other facilities.

“…This method has been proposed in 1992 [4] and subsequently intensively studied (first at LISOL) and developed [5][6][7][8][9][10][11][12][13]. Known as In-Gas Laser Ionization and Spectroscopy (IGLIS), it is based on stopping of nuclear reaction products in a gas cell and subsequent selective resonance laser ionization [5][6][7][8][9][10][11][12][13].…”

“…Basing on the LISOL SPIG efficiency of 66% [8], we can expect the efficiency of the FLNR system with SPIG to be 67% or higher. Thus, the system developed in FLNR looks more preferable due to the less beam losses and less ion energy dispersion.…”

Abstract.A project devoted to the production and study of neutron rich heavy nuclei (GALS -project) is being realized at Flerov Laboratory for Nuclear Reactions (FLNR) -JINR. GALS is planned to exploit available beams from the U-400M cyclotron in low energy multi-nucleon transfer reactions to study exotic neutronrich nuclei located in the "north-east" region of nuclear map. Products from 4.5 to 9 MeV/nucleon heavy-ion collisions, such as 136 Xe on 208 Pb, are to be captured in a gas cell and selectively laser-ionized in a sextupole (quadrupole) ion guide extraction system.

“…Filled with buffer gas, such a device can also serve for controlled cooling and bunching of the resulting ion ensemble to enhance temporal and spatial beam quality. 17) In the third approach the atoms are stored in a noble gas buffer gas cell for many ms with the interaction volume being illuminated by the laser light. Laser repetition rates of $100 Hz are sufficient for efficient resonant ionization.…”

Trace isotope determination techniques based on resonant optical excitation of atoms, i.e. resonance ionization mass spectrometry, are well known. Especially concerning the determination of low level contaminations of long-lived radioactive isotopes in environmental or technical samples, outstanding specifications have been demonstrated. Nevertheless, there is still an -even increasing -deficiency in the routine application of these techniques. This fact is ascribed to the complexity of operation and the still only limited reliability of the tunable laser systems in use. While fixed frequency lasers have widely conquered almost all fields of basic and applied research and development, the application of tunable and particularly narrow band width lasers is almost exclusively limited to the delicate fields of fundamental research and quantum optical investigations. Thus, routine investigations in the field of isotope sciences are still the domain of all kind of conventional radiometric, mass spectrometric or alternative optical techniques, but widely excluding resonant optical interaction. This review will discuss the state of the art of these resonant laser techniques developed with special emphasis on elemental isotope selective determination techniques, elucidate reasons for the slight stagnation observed in this field and stimulate further possible developments and applications.
