“Sources of Research” for the Virtual Reconstruction of Ancient Monuments: The Case of Architectural Models
2023
The use of architectural scale models, also known by the French word maquette or the Italian names plastico or modello, is an ancient practice, which prob-ably began when architecture emerged from its purely practical and utilitarian phase to become a formal category of knowledge with specifically sought-after and deliber-ately selected characteristics, linked to the increased dimensions and the enrichment of forms [1]. The model constitutes a representation, generally on a smaller scale and made of different materials but similar in effect, of a work to be created. Models are made of various materials, in accordance with the tastes of Scholars and with need, such as wood, wax, terracotta, …
H$^{-}$ extraction systems for CERN’s Linac4 H$^{-}$ ion source
2018
Linac4 is a 160 MeV linear H accelerator at CERN. It is an essential part of the beam luminosity upgrade of the Large Hadron Collider (LHC) and will be the primary injector into the chain of circular accelerators. It aims at increasing the beam brightness by a factor of 2, when compared to the currently used 50 MeV linear proton accelerator, Linac2. Linac4’s ion source is a cesiated RF-plasma H ion source. Several beam extraction systems were designed for H beams of 45 keV energy, 50 mA intensity and an electron to H ratio smaller than 5. The goal was to extract a beam with an rms-emittance of mm mrad. One of the main challenges in designing an H extraction system is dumping of the co-extra…
Exact reconstruction of thz sub-λ source features in knife-edge measurements
2013
The spatial features of a sub-wavelength terahertz source are not accessible using time-integrated knife-edge techniques due to the non-separable space-time nature of the radiated field and to systematic modifications induced by the blade itself. We show that combining knife-edge with a time resolved electro-optical sampling, the space-time coupling can be addressed and the source field profile can be exactly reconstructed.
Il «faticato peregrinaggio» di Isidoro Carini negli archivi e nelle biblioteche di Spagna (1881-1882)
2021
ITALIANO: Attraverso la Relazione di Isidoro Carini sulla missione negli archivi e nelle biblioteche spagnole nel 1881-1882 e dallo studio delle vicende della pubblicazione dei suoi risultati si ricostruisce l’avvio dell’utilizzazione delle fonti iberiche per la storia medievale siciliana e nazionale e il contesto della storiografia sulla Sicilia medievale alla fine dell’Ottocento. / ENGLISH: The Relazione by Isidoro Carini about his research mission in Spain (1881-1882) and the events of its publication allow to reconstruct the beginnings of both the use of Spanish sources for the Sicilian and Italian medieval history and the context of the Sicilian medieval historiography at the end of th…
