Note: Enhanced production of He+ from the Versatile Ion Source (VIS) in off-resonance configuration

Review of Scientific Instruments (2014)

G. Castro D. Mascali L. Celona S. Gammino Claudia Caliri

The Versatile Ion Source (VIS) is a microwave discharge ion source installed at INFN-LNS and here used as test-bench for the production of high intensity low emittance proton beams and for studies on plasma physics. A series of measurements have been carried out with VIS in order to test the source with light ions. In particular a He+ beam has been characterized in terms of plasma discharge parameters. The experiment has been triggered by the observation of X-radiation emission from the plasma for some configuration of the magnetic field profile. The plasma electron energy distribution function is in fact modified when in some regions of the plasma chamber under-resonance discharge takes place, fulfilling the condition that allows the electromagnetic wave to electrostatic wave conversion. These tests allowed obtaining more than 50 mA of He+ beams.

First Simulations on Higher-Efficiency Betavoltaic Battery Integrated with Electrets for Space, Medicine and Remote Sensing Applications

C. Altana Francesco Cottone D. Mengoni

The results of Geant4 simulations using Montecarlo based code to explore suitable beta emitters and the interaction of beta rays with matter for the development of nuclear betavoltaic battery are shown. Such developments arise from the need of reliable, long-lived, high energy-density power sources for operating electrical systems in hostile and inaccessible environments, at variance with conventional electrochemical batteries with limited longevity and a strong tendency to degrade under extreme environmental conditions. The choice of beta emitters is due to the higher energy conversion efficiency and security when compared with other types of nuclear batteries. The geometrical efficiency of beta-particles interaction with different type of semiconductors is investigated.

Design of a Novel Smart Rad-Hard Fast Detection System for Radioactive Ion Beam Tagging and Diagnostics

2021 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC) (2022)

L. Acosta C. Altana G. Cardella A. Castoldi M. Costa

Many facilities are upgrading their infrastructures to deliver high intensity Radioactive Ion Beams (RIBs) (10 ⁶ pps or higher). RIBs are at the frontier in nuclear physics experiments, also having potential in interdisciplinary applications, especially in medical physics. We are designing a novel detection system for RIBs diagnostics and tagging based on an array of Silicon Carbide detectors and on custom frontend electronics at present designed to cope with the specifications of the new fragment separator, FRAgment In-fligth SEparator (FraISe), presently under construction at INFN-LNS in Catania (Italy). In this contribution we introduce the design conception of the proposed system and we present and critically analyse the results of the first experimental qualification of the individual components.

Effect of advanced nanowire-based targets in nanosecond laser-matter interaction (invited)

Review of Scientific Instruments (2016)

G. Lanzalone C. Altana D. Mascali A. Muoio L. Malferrari

An experimental campaign aiming to investigate the effects of innovative nanostructured targets based on Ag nanowires on laser energy absorption in the ns time domain has been carried out at the Laser Energy for Nuclear Science laboratory of INFN-LNS in Catania. The tested targets were realized at INFN-Bologna by anodizing aluminium sheets in order to obtain layers of porous Al2O3 of different thicknesses, on which nanowires of various metals are grown by electro-deposition with different heights. Targets were then irradiated by using a Nd:YAG laser at different pumping energies. Advanced diagnostic tools were used for characterizing the plasma plume and ion production. As compared with targets of pure Al, a huge enhancement (of almost two order of magnitude) of the X-ray flux emitted by the plasma has been observed when using the nanostructured targets, with a corresponding decrease of the “optical range” signal, pointing out that the energetic content of the laser produced plasma was remarkably increased. This analysis was furthermore confirmed from time-of-flight spectra.

New Results from the NUMEN Project

C. Agodi F. Cappuzzello L. Acosta C. Altana P. Amador-Valenzuela

NUMEN aims at accessing experimentally driven information on Nuclear Matrix Elements (NME) involved in the half-life of the neutrinoless double beta decay (0νββ), by high-accuracy measurements of the cross sections of Heavy Ion (HI) induced Double Charge Exchange (DCE) reactions. First evidence about the possibility to get quantitative information about NME from experiments is found for the (^18O,^18Ne) and (^20Ne,^20O) reactions. Moreover, to infer the neutrino average masses from the possible measurement of the half-life of 0νββ decay, the knowledge of the NME is a crucial aspect. The key tools for this project are the high resolution Superconducting Cyclotron beams and the MAGNEX magnetic spectrometer at INFN Laboratori Nazionali del Sud in Catania (Italy). The measured cross sections are extremely low, limiting the present exploration to few selected isotopes of interest in the context of typically low-yield experimental runs. A major upgrade of the LNS facility is foreseen in order to increase the experimental yield of at least two orders of magnitude, thus making feasible a systematic study of all the cases of interest.

X-ray Imaging and preliminary studies of the X-ray self-emission from an innovative plasma-trap based on the Bernstein waves heating mechanism

Bulletin of the American Physical Society (2013)

Claudia Caliri Francesco Paolo Romano D. Mascali S. Gammino A. Musumarra

L. CELONA, L. NERI, C. ALTANA, INFN- LNS — Electron Cyclotron Resonance Ion Sources (ECRIS) are based on ECR heated plasmas emitting high fluxes of Xrays. Here we illustrate a pilot study of the X-ray emission from a compact plasmatrap in which an off-resonance microwave-plasma interaction has been attempted, highlighting a possible Bernstein-Waves based heating mechanism. EBWs-heating is obtained via the inner plasma EM-to-ES wave conversion and enables to reach densities much larger than the cut-off ones. At LNS-INFN, an innovative diagnostic technique based on the design of a Pinhole Camera (PHC) coupled to a CCD device for X-ray Imaging of the plasma (XRI) has been developed, in order to integrate X-ray traditional diagnostics (XRS). The complementary use of electrostatic probes measurements and X-ray diagnostics enabled us to gain knowledge about the high energy electrons density and temperature and about the spatial structure of the source. The combination of the experimental data with appropriate modeling of the plasma-source allowed to estimate the X-ray emission intensity in different energy domains (ranging from EUV up to Hard X-rays). The use of ECRIS as X-ray source for multidisciplinary applications, is now a concrete perspective due to the intense fluxes produced by the new plasma heating mechanism.
