... It is therefore interesting to investigate a new route based on the insertion of a 45 Sc target close to the SPES one, exploiting the 45 Sc(n,p) 45 Ca nuclear reaction; in this case, only a chemical separation is required. To estimate the 45 Ca production it is necessary to know the cross section at neutron energies available at SPES (1-10 MeV) [570]: since there are no experimental data up to 6 MeV, it is proposed to measure the 45 Sc(n,p) 45 Ca cross section up to 10 MeV. ...
The next years will see the completion of the radioactive ion beam facility SPES (Selective Production of Exotic Species) and the upgrade of the accelerators complex at Istituto Nazionale di Fisica Nucleare – Legnaro National Laboratories (LNL) opening up new possibilities in the fields of nuclear structure, nuclear dynamics, nuclear astrophysics, and applications. The nuclear physics community has organised a workshop to discuss the new physics opportunities that will be possible in the near future by employing state-of-the-art detection systems. A detailed discussion of the outcome from the workshop is presented in this report.
... The work reported here falls under the broad category of atomic vapour laser isotope separation (AVLIS) schemes [14]. More particularly, two colour resonant ionization studies on stable Mo were performed at the off-line laboratory that was recently installed in LNL [15]. Two dye lasers were used in order to excite Mo in a hollow cathode lamp (HCL) for measurements of multiphoton/ multicolour ionization of the metal vapour. ...
We report on measurements of resonant three-step, two-colour ionization of atomic molybdenum, using a hollow cathode lamp (HCL) with optogalvanic detection. Wavelength scans were made for two specific transitions involved in the ionization pathways under investigation, namely 4d5(6S)5s 7S3 - 4d5(6S)5p 7P4 and 4d5(6S)5p 7P4 - 4d5(6S)6d 7D5.So-called ‘slow’ and ‘fast’ optogalvanic signals were observed for each pathway. Results confirm the HCL as a cost effective spectroscopic investigation tool. In particular its use in the optogalvanic mode of operation allows one to precisely, easily and reliably tune the wavelength of one or more lasers to resonances of interest for experiments in the general domain of atomic vapour laser isotope selection (AVLIS). The measurements are closely related to the Selective Production of Exotic Species (SPES) project at the ISOL facility and were performed in the recently established laser laboratory in Legnaro National Laboratories of INFN.
... Selective Production of Exotic Species (SPES) 13 is a secondgeneration ISOL facility on which the short-and longterm strategies of the laboratory are centered [74]. It is an interdisciplinary project, ranging over nuclear physics, nuclear medicine, and materials science. ...
Biomedical applications at high-energy particle accelerators have always been an important section of the applied nuclear physics research. Several new facilities are now under constructions or undergoing major upgrades. While the main goal of these facilities is often basic research in nuclear physics, they acknowledge the importance of including biomedical research programs and of interacting with other medical accelerator facilities providing patient treatments. To harmonize the programs, avoid duplications, and foster collaboration and synergism, the International Biophysics Collaboration is providing a platform to several accelerator centers with interest in biomedical research. In this paper, we summarize the programs of various facilities in the running, upgrade, or construction phase. © Copyright © 2020 Patera, Prezado, Azaiez, Battistoni, Bettoni, Brandenburg, Bugay, Cuttone, Dauvergne, de France, Graeff, Haberer, Inaniwa, Incerti, Nasonova, Navin, Pullia, Rossi, Vandevoorde and Durante.
... AGATA is a truly universal high-resolution spectrometer, capable of measuring γ rays from a few tens of keV to beyond 10 MeV, with unprecedented efficiency, excellent position resolution for individual γ -ray interactions and correspondingly unparalleled angular resolution, and very high count-rate capability. These features will give rise to a resolving power that is in specific cases up to two orders of magnitude larger than current arrays, and allow AGATA to be operated in diverse environments such as using relativistic beams from the FAIR/Super-FRS facility [11,12], high-intensity ISOL beams from the secondgeneration Radioactive Ion Beam (RIB) facilities (HIE-ISOLDE [13], SPES [14], SPIRAL2 [15]), and at the highintensity stable beam facilities at GANIL [15], JYFL [16], and LNL [17]. ...
... The latter constitute an almost unexplored territory, ideal for investigations with AGATA coupled to light charged-particle detectors, using intense stable beams. For example, reactions such as 6,7 Li on 6,7 Li, 9 Be, 10,11 B, and 12,13 C targets, will lead, after a single proton evaporation, to the population of unbound states in 13 B, 15 C, 17 4 Shape coexistence occurs when different microscopic configurations correspond to similar binding energies, as illustrated by the wave functions of 0 + states in the neutron-rich krypton isotopes beyond N = 60 (left), where oblate and prolate shapes are expected to coexist. Low-energy Coulomb excitation is an ideal tool to pin down their structure. ...
... The Laboratori Nazionali di Legnaro (LNL) [17] provides heavy-ion beams from the 15 MV Tandem and from the ALPI superconducting LINAC, the latter either coupled to the Tandem or to the heavy-ion injector PIAVE. Stable beams range from protons to lead with energies up to 10-15 MeV/A. ...
New physics opportunities are opening up by the Advanced Gamma Tracking Array, AGATA, as it evolves to the full 4\(\pi \) instrument. AGATA is a high-resolution \(\gamma \)-ray spectrometer, solely built from highly segmented high-purity Ge detectors, capable of measuring \(\gamma \) rays from a few tens of keV to beyond 10 MeV, with unprecedented efficiency, excellent position resolution for individual \(\gamma \)-ray interactions, and very high count-rate capability. As a travelling detector AGATA will be employed at all major current and near-future European research facilities delivering stable and radioactive ion beams.
... For many years, the number of new large accelerators in the world was almost flat (Fig. 3). In the past years, however, new projects have been approved and in the coming years several new facilities will become available, including HIAF in China [113], SPIRAL2 in France [114], SPES in Italy [115], HIE-ISOLDE at CERN [116], ELI is East Europe [117] and FRIB in USA [118]. These new ion accelerators have scientific programs in hot and cold QCD or nuclear structure physics [6]. ...
Applied nuclear physics is an essential part of the research activity at many particle accelerators. New, large accelerator facilities are currently under construction in Europe, Asia, and USA. These machines will be able to produce radioactive ion beams, and to increase the intensity and the energy of the heavy ions well beyond the limits currently available at the therapy or research facilities. The upcoming facilities open new opportunities for research in biomedical applications that require these special properties, such as particle radiography, radioactive beam imaging, ultra-high dose rates and new ions for therapy. Moreover, space radiation research and materials science can successfully exploit these new centers. The new facilities can pave the way to many future applications of nuclear physics for the benefit of the society. In this paper we will summarize the current status of applied sciences at high-energy accelerators, describe the characteristics of some of the machines under construction (FAIR, NICA, RAON, ELI) and discuss the new opportunities offered by these facilities in applied sciences.
... The modified VADLIS ion source has been shown to be reliable and highly versatile, while offering an improved efficiency compared to the standard VADLIS. These characteristics are expected to be particularly important for next-generation ISOL facilities (SPES [26], SPIRAL2 [27], ISOL@MYRRHA [28]) where the target lifecycle is expected to be long (weeks-months), or for cases where a wide variety of species will need to be extracted from a single target-ion source assembly (e.g. CERN-MEDICIS [29]). ...
The Versatile Arc Discharge and Laser Ion Source (VADLIS) is a recently established ion source for the CERN-ISOLDE radioactive ion beam facility. It offers either electron-impact ionization (VADIS-mode) or resonance laser ionization (RILIS-mode). The choice of operating mode depends on the element of interest or the required beam purity. Particle-in-cell simulations using the VSim software show that the ion extraction efficiency of the VADLIS in RILIS-mode can be improved if it is equipped with an insulated extractor plate, to which an optimal voltage can be applied. This enables optimization of the RILIS-mode ion extraction independently of the electron density. Experiments have been performed using a prototype VADLIS with an adjustable extractor plate voltage for the generation of gallium ion beams at the off-line separator as well as magnesium, molybdenum and mercury ion beams at ISOLDE. A factor > 2 increase of the VADLIS efficiency in RILIS-mode has been achieved.
