Optimization of a hot-cavity type resonant ionization laser ion source
2015
TuePS05; International audience; Resonant Ionization Laser Ion Source (RILIS) is nowadays an important technique in many RadioactiveIon Beam (RIB) facilities for its reliability and ability to ionize efficiently and element selectively.Grand Accélérateur National d’Ions Lourds (GANIL) Ion Source using Electron Laser Excitation(GISELE) is an off-line test bench for RILIS developed to study a fully operational resonant laserion source at GANIL facility. The ion source body has been designed as a modular system toinvestigate different experimental approaches by varying the design parameters, to develop the futureon-line laser ion source. The aim of this project is to determine the best technic…
INVESTIGATION OF THE UNDERGROUND BUILDING HERITAGE AND THE MECHANISM OF WATER FLOWING IN QANĀTS IN PALERMO THROUGH INNOVATIVE SURVEYING TECHNIQUES
2021
Abstract. The valorisation, protection and preservation policies for the underground building heritage are often difficult to implement due to an inadequate knowledge of hypogeal constructions. The complex and widespread underground structures of the vast “Cavo” Heritage (“horizontal wells”, “shelf wells” or “well tunnels”), so called qanāts, hidden underground and built over the centuries in Palermo, representing an evocative testimony to the history of water culture in the ancient city. Through the historical and constructive analyses and the implementation and development of measurement and 3D representation and visualization, first actions have been carried out. The paper will present t…
Status and development of the MARA low-energy branch
2018
The MARA Low-Energy Branch is under development at the Accelerator Laboratory of the University of Jyvaskylä. The facility will be employed for laser ionisation and spectroscopy studies and for mass measurements of nuclei close to the proton drip line. This article presents an updated status of the ongoing development of the different parts of this facility, including the buffer gas cell, the ion transport system, the laser system and the detector stations. peerReviewed
