«Luigi Santarella. Progetti e opere in Puglia». Note sulla mostra documentaria / «Luigi Santarella. Projects and Works in Apulia». Notes on the Documentary Exhibition
No full textIdeata e curata da Anna De Palma con il supporto scientifico di Lorenzo Pietropaolo, questa mostra — inaugurata a Corato il 15 settembre 2023 in occasione della relativa Giornata di studi su Luigi Santarella — ha presentato sia agli studiosi che al grande pubblico (e in particolare alle più giovani generazioni) una selezione di materiali in gran parte inediti (disegni, edizioni originali di libri, fotografie e documenti) provenienti dall'Archivio Santarella di Milano. Allestita al piano terreno della casa progettata da Santarella per Antonio Capano nel 1913 (conosciuta come “Palazzo Santarella”), la mostra è stata organizzata in due sezioni. Nella prima sezione, i materiali esposti hanno documentato la ricostruzione del profilo biografico di Luigi Santarella, la sua produzione scientifica con l'editore Ulrico Hoepli — che nel corso dei decenni ha contribuito a formare più di una generazione di ingegneri italiani — e il suo impegno professionale nella costruzione di ponti in cemento armato. Nella seconda sezione, sono stati esposti documenti e disegni relativi a progetti e opere civili e industriali di Santarella in Puglia, negli anni dal 1911 al 1916, vale a dire i primi anni di pratica professionale dopo la laurea in ingegneria al Politecnico di Milano nel 1910. Questi primi lavori, ancora poco studiati, sono stati presentati insieme per la prima volta in mostra, con l’auspicio di offrire nuovi spunti e sollecitare nuove linee di indagine per ulteriori approfondimenti e studi sistematici. A corredo del testo, è pubblicata un’ampia rassegna dei materiali esposti, riprodotti digitalmente da Archeoclub d’Italia, su permesso e cortesia dell’Archivio Santarella di Milano.Conceived and curated by Anna De Palma with the scientific support of this author, this exhibition, which opened in Corato on 15 September 2023 on the occasion of the related Study Day on Luigi Santarella, presented to both scholars and the general public (and especially to a younger generation) a selection of mostly unpublished materials (drawings, original book editions, photographs, and documents) from the Santarella Archive based in Milan. Set up on the ground floor of the house designed by Santarella for Antonio Capano in 1913 (known as “Palazzo Santarella”), the exhibition was organized into two sections. In the first section, the materials on display documented the reconstruction of the biographical profile of Luigi Santarella, his scientific production with the publisher Ulrico Hoepli, which over decades has contributed to training more than a generation of Italian engineers, and his professional engagement in the construction of bridges in reinforced concrete. In the second section, on view were documents and drawings pertaining to Santarella’s civil and industrial projects and works in Apulia, spanning the years from 1911 to 1916, that is, his first years of professional practice since graduating in engineering from the Polytechnic of Milan in 1910. These early works are still little-researched and were presented together for the first time in the exhibition, offering fresh insights and opening new lines of inquiry for further in-depth, systematic studies. In the following pages, an extensive review of the materials on display is published, digitally reproduced by Archeoclub d’Italia, under the permission and courtesy of the Santarella Archive of Milan
Una prima ricognizione nell’archivio di famiglia. Su alcune opere giovanili di Luigi Santarella in Puglia / A Preliminary Survey from the Family Archive: on Some Early Works by Luigi Santarella in Apulia
No full textIl contributo illustra gli esiti di una prima indagine condotta presso l’Archivio Santarella di Milano, alla quale l’autore ha partecipato su invito dell’Archeoclub e d’intesa con la proprietà dell’archivio privato della famiglia dell’ingegnere. Lo studio si è concentrato sui materiali rivenienti dall’archivio professionale di Luigi Santarella, relativi ai suoi primi lavori e alla sua attività editoriale. Una parte significativa di questa documentazione - per lo più inedita - riguarda incarichi svolti in Puglia tra il 1911 e il 1916. Considerate nel contesto dello sviluppo delle culture tecniche nella regione all'inizio del Novecento, le residenze progettate da Santarella per facoltosi committenti dimostrano il suo ruolo di protagonista nella diffusione delle tecniche costruttive in cemento armato in quei territori. I cementifici di Barletta, Brindisi e Taranto mettono in luce il contributo di Santarella come progettista e come socio azionista nella fondazione di una “cultura del cemento” industriale in Puglia. Il presente studio intende analizzare la rilevanza di questi lavori giovanili, indicando ulteriori linee di indagine che questi esempi suggeriscono per una riflessione approfondita sull’opera di Santarella nel suo complesso.This paper investigates the outcomes of a preliminary survey conducted in the Santarella Archive, Milan, in which this author took part on the invitation of the Archeoclub and in agreement with the owner of the private archives of the engineer’s family. The present study focuses on the materials in Luigi Santarella’s professional archive pertaining to his early works, as well as to his editorial activities. A significant part of this documentation regards assignments carried out in Apulia between 1911 and 1916. Considered in the context of the development of technical cultures in the region at the beginning of the twentieth century, the mansions Santarella designed for wealthy clients demonstrate his role among the protagonists of the dissemination of building techniques in reinforced concrete in those territories. The cement plants in Barletta, Brindisi and Taranto illuminate Santarella’s contribution as designer and shareholder of investing companies in founding an industrial “culture of cement” in Apulia. The present study intends to analyze the relevance of these early works pointing at further lines of inquiry that these examples suggest towards an in-depth reflection on the work of Santarella overall
The CLYC-6 and CLYC-7 response to γ-rays, fast and thermal neutrons
No full textThe crystal Cs2LiYCl6:Ce (CLYC) is a very interesting scintillator material because of its good energy resolution and its capability to identify γ-rays and fast/thermal neutrons. The crystal Cs2LiYCl6:Ce contains 6Li and 35Cl isotopes, therefore, it is possible to detect thermal neutrons through the reaction 6Li(n, α)t while 35Cl ions allow to measure fast neutrons through the reactions 35Cl(n, p)35S and 35Cl(n, α)32P. In this work two CLYC 1′′1′′ crystals were used: the first crystal, enriched with 6Li at 95% (CLYC-6) is ideal for thermal neutron measurements while the second one, enriched with 7Li at >99% (CLYC-7) is suitable for fast neutron measurements. The response of CLYC scintillators was measured with different PMT models: timing or spectroscopic, with borosilicate glass or quartz window. The energy resolution, the neutron-γ discrimination and the internal activity are discussed. The capability of CLYC scintillators to discriminate γ rays from neutrons was tested with both thermal and fast neutrons. The thermal neutrons were measured with both detectors, using an AmBe source. The measurements of fast neutrons were performed at the Frascati Neutron Generator facility (Italy) where a deuterium beam was accelerated on a deuterium or on a tritium target, providing neutrons of 2.5 MeV or 14.1 MeV, respectively. The different sensitivity to thermal and fast neutrons of a CLYC-6 and of a CLYC-7 was additionally studied. © 2015 Elsevier B.V. All rights reserved
Thermal and fast neutron detection with two CLYC scintillators
No full textThe crystal Cs2LiYCl6:Ce (CLYC) is a very interesting scintillator material because of its excellent energy resolution and its capability to identify gamma rays and fast/thermal neutrons. In this work, the response to gamma, thermal and fast neutrons of two CLYC 1x1 crystals was measured: the first one, enriched with 6Li at 95% is ideal for thermal neutron measurements while the second one, enriched with 7Li at 99% is suitable for fast neutron measurements. The crystals were coupled to quartz window R6231-1000MOD HAMAMATSU PMTs. The thermal neutrons were measured in both detectors using an AmBe source in the gamma spectroscopy laboratory of the University of Milano, Italy. The measurements of fast neutrons were performed at Frascati (Italy) Neutron Generator facility providing neutrons of 14.1 MeV and 2.5 MeV. © 2014 IEEE

High-resolution wide-range dynamic neutron monochromators
No full textThis work proposes the concept of a high-resolution wide-range dynamic neutron monochromator able to operate up to a few eV, thus significantly extending the reliable operating neutron energy range of the state-of-the-art crystal-based devices, and to improve energy resolution in the epithermal range if compared to mechanical choppers. The proposed device is based on a radiation-hard aluminium nitride (AlN)/diamond heterostructure, operating as a super-high-frequency (> 3 GHz) high-speed (> 10000 m/s) acoustic resonator. The resulting surface acoustic wave (SAW) acts as a dynamic grating for the incoming neutrons: as long as neutron speed is lower than (or at least comparable to) SAW speed, diffraction angles are significantly enhanced, thus allowing for neutron beam monochromatization to be effective up to the eV energy range. SAW amplitude can be electrically tuned to increase first-order reflectivity, leading to an enhanced intensity of the monochromatized beam. Copyright © EPLA, 2015

No full textMuseo: architettura, città, territorio. Una conversazione “didattica” con Guido Canella
No full textNell’ultimo decennio, in numerose occasioni è stato ripercorso il contributo di Guido Canella alla cultura architettonica del Secondo Novecento. A testimoniarne il modo rigoroso e generoso con cui sapeva porsi in dialogo con i suoi allievi, si propone qui una conversazione inedita con il maestro milanese, che verte sui concetti di «monumento» e di «contesto» nella prospettiva del «museo a scala territoriale». A partire dalla distinzione tra «sistemi museali propri di concentrazione e di posizione» e «sistemi museali impropri di diffusione e di movimento» proposta da Canella, il dialogo affronta la possibilità di sperimentare in uno specifico territorio (la Capitanata, in Puglia) l’idea di un «museo-progetto», «ottenibile tramite il riconoscimento della propagazione sul territorio di presenze con caratteri di omogeneità storico-culturale, avvenuta in una data contestualità insediativa», capace di interagire con la struttura produttiva e sociale di quello stesso territorio.The events presenting two remarkable books such as Guido Canella 1931-2009 [edited by Enrico Bordogna, Gentucca Canella, Elvio Manganaro; Franco Angeli, Milan 2014] and Guido canella, Architetti italiani nel Novecento [Christian Marinotti edizioni, Milan 2010] were tributes payed in 2016 and 2010 by the Accademia nazionale di san luca to Canella’s outstanding work. in the last decade other events (the seminar “Carlo Aymonino e Guido Canella. Architetture che dialogano”, the exhibitions “Guido i’ vorrei che tu Carlo ed io fossimo presi per incantamento...” and “Per Aldo Rossi. Dieci anni dopo”) recalled the long lasting dialogue he had with other two masters of italian architecture such as Carlo Aymonino and Aldo Rossi. With the more modest aim to highlight the rigorous and passionate way Canella was used to dialogue with his students, here by it is presented the complete transcript of a conversation we had in 2004 in his studio in Milan, on the issues of my PhD studies. Canella reviewed the transcript at the time, granting me to include it in my doctoral thesis. As I was studying the concepts of “monument” and “context” in the perspective of the museum, I intended to experiment in Apulia his theoretical statement for the “museum as a project” that interacts with cultural, social and economical dynamics. Through this conversation, it is possible to glimpse some of his views on architecture, city and territory, on the civic role of the architect, as well as other fundamentals of his lesson that still inspire those who continue his legacy, and those younger architects and scholars who, as the Author, had the chance to discuss with him
Feasibility study of an intense D-T fusion source: "The new sorgentina"
No full textThe international community agrees on the importance to build a large facility devoted to test and validate materials to be used in harsh neutron environments. Such a facility, proposed by ENEA, reconsiders a previous study known as "Sorgentina" but takes into account new technological development so far attained. The "New Sorgentina" Fusion Source (NSFS) project is based upon an intense D-T 14 MeV neutron source achievable with T and D ion beams impinging on 2 m radius rotating targets. NSFS produces about 1 × 1013 n cm-2 s-1 over about 50 cm 3. Larger volumes of lower neutron flux will be available (e.g. for TBM experiments) as well as collimated channels to study some features of the ITER neutron camera. The NSFS facility will overcome problems related to the ion source and accelerating system, by means of an upgraded version of the JET-PINI ion beams. NSFS has to be intended as an European facility that may be realized in a few years, once provided a preliminary technological program devoted to the operation of the ion source in continuous mode, target heat loading/removal, target and tritium handling, inventory as well as site licensing. In this contribution, the main characteristics of NSFS project will be presented. © 2014 Elsevier B.V
