Alexandr Sukorov’s passıng world
The author of this article concentrates his attention on the films directed by Alexandr Sokurov, a distinguished contemporary Russian filmmaker. Syska describes the political and aesthetical background of Sokurov’s works, underlying their key motifs: melancholy, nostalgia, reminiscences, decay of physical world, memories and time. The author mentions autobiographical components of Sokurov’s screenplays, describes his childhood defined by eternal displacement of his family, as well as the adultness - with political troubles caused by anti-communism attitude and close friendship with Tarkovsky. Syska analyzes the literary context of Sokurov’s films, cultural paradigm, religious character of film narration and theme of carnal sacrifice. All of them allow him to describe the human as someone who is deeply devoted to the internal world of memories, nostalgia, passing time and intimate relationship with dying parents

Entwicklung von Beam Halo Monitoren mit strahlungsharten Sensoren für den Europäischen XFEL und Demonstration der Technologie bei FLASH
The European X-Ray Free-Electron Laser (E-XFEL), currently under construction in Hamburg, Germany, is intended to be an international linear accelerator (linac) based user facility. Its electron beam can carry maximal average power of 600 kW. A beam with such a high power needs to be carefully transmitted through the machine and safely dumped after utilization. This is supported by various diagnostics tools. A Beam Halo Monitor (BHM) based on synthetic diamond and sapphire sensors has been designed.
Diamond sensors are developed by the company element6 for the detection of ionizing radiation and used previously elsewhere. Sapphire sensors are in this thesis applied for the first time.
The BHM concept has been applied already at the Free-electron Laser in Hamburg (FLASH). A module with four diamond and four sapphire sensors was designed, installed inside the beam pipe, commissioned, calibrated and has been successfully operated for 4 years. The system contributed significantly to safe and efficient operation of FLASH.
Both types of the sensors for the BHM were characterized. Measurements of radiation tolerance are done in a 10 MeV electron beam for polycrystalline CVD (pCVD) diamond sensors for the first time up to a dose of 10 MGy and for sapphire sensors up to 5 MGy. The charge collection efficiency (CCE) drops as a function of the absorbed dose, is however still sufficient for application as a BHM.
To improve a main sensor characteristic, the charge collection efficiency, for sapphire sensors the impurity concentration was reduced and different growth techniques were compared. Finally, charge collection efficiency of about 5 % for a bias voltage of 500 V was reached.
The BHM concept for the XFEL is designed and in the construction phase.Der European X-Ray Free-Electron Laser (E-XFEL), dessen Aufbau zur Zeit in Hamburg stattfindet, soll als international organisierte LINAC basierte Strahlungsquelle für Nutzer betrieben werden. Die mittlere Leistung im Elektronenstrahl wird 600 kW betragen. Ein Strahl mit so hoher Leistung muss sicher durch den Beschleuniger gesteuert, und nach seiner Nutzung sicher am vorgesehenen Ort vernichtet werden. Die Führung des Strahls wird von verschiedenen Diagnoseinstrumenten unterstützt. Hierzu zählt ein Beam Halo Monitor, der Sensoren aus hochreinem Diamant- und Saphirkristallen nutzt. Diamantsensoren wurden speziell für den Nachweis ionisierender Strahlung von der Firma Element6 entwickelt und wurden bereits an anderen Beschleunigen verwendet. Saphiresenoren werden in dieser Arbeit zum ersten Mal von verschiedenen Herstellern getestet und verwendet.
Das Konzept eines solchen Beam Halo Monitors wurde im Rahmen dieser Arbeit bereits beim Free-Electron Laser in Hamburg (FLASH) entwickelt und angewandt. Hier wurde ein Modul mit jeweils 4 Diamant- und 4 Saphirsensoren installiert, in Betrieb genommen und getestet. Seit nunmehr 4 Jahren ist es ohne Ausfall in Betrieb und hat in dieser Zeit signifikant zur Erhöhung der Effizienz von FLASH beigetragen.
Vor dem Einbau bei FLASH wurden beide Sensortypen charakterisiert. Polykristaline CVD (pCVD) Diamantsensoren wurden in einem 10 MeV Elektronenstrahl mit bis zu 10 MGy und Saphirsensoren bis zu 5 MGy Dosis getestet. Die sogenannte Charge Collection Efficiency (CCE) fällt dabei in Abhängigkeit von der applizierten Dosis ab, bleibt aber immer noch ausreichend hoch, so dass die Sensoren für einen BHM verwendet werden können.
Ferner wurde der Einfluss der Reinheit von Saphirsensoren auf die Charge Collection Efficiency untersucht. Die Konzentration Verunreinigungen wurde bei Auswahl der Sensoren verringert, und verschiedene Herstellungsverfahren wurden betrachtet. Im Resultat konnten Sensoren mit einer Charge Collection Efficiency von 5% bei einer Spannung von 500 V hergestellt werden.
Das Konzept für den XFEL ist entwickelt und bereits in der Phase der Realisierung

Alexandr Gel'evič Dugin's Neo-Eurasianist Ideology in Contemporary Russia
openL’oggetto della tesi consiste in un’analisi dell’ideologia neo-eurasista dal punto di vista di Alexandr Dugin, filosofo autore de “La Quarta Teoria Politica” e di svariati saggi ad essa correlati. L’obiettivo di tale ricerca è molteplice, sviluppandosi in tre parti: la prima concerne la ricostruzione storica di alcune dinamiche della società e della cultura russa che hanno gettato le fondamenta per questa corrente di pensiero, ripercorrendo le tappe dell’eurasismo classico e dei suoi più noti esponenti. La seconda entra nel merito della Quarta Teoria Politica e dell’idea di Eurasia per Alexandr Dugin, attraverso le concezioni di civiltà, popolo e grandi spazi, decostruendo per quanto possibile la dialettica del pensatore. Questa è l parte di gran lunga più densa ed importante, dove sono esposte le caratteristiche esoteriche e strettamente metafisiche del pensiero di Dugin. Infine, l’ultima branca è dedicata alla prassi ideologica per come si sta manifestando nella Russia contemporanea, gettando uno sguardo obiettivo sull’effettiva influenza del filosofo nella politica della Federazione. In conclusione, l’eurasismo, così come il neo-eurasismo, sono esposti in questa tesi come un aspetto poco conosciuto ma fondamentale della storia delle dottrine politiche, che ha un reale impatto nel presente stato delle cose in Russia, e in particolare nella crisi Russo-Ucraina e nell'approccio delle relazioni con i Paesi membri della NATO.The object of the thesis consists of an analysis of the neo-Eurasianist ideology from the viewpoint of Alexandr Dugin, philosopher and author of "The Fourth Political Theory" and several related essays. The objective of this enquiry is multiple, developing into three parts: the first one concerns the historical reconstruction of some dynamics of Russian society and culture which laid the foundations for this way of thought, retracing the steps of classical Eurasianism and its most famous representatives. The second gets into the Fourth Political Theory and the idea of Eurasia for Alexander Dugin, through the conceptions of civilization, people and large spaces, deconstructing the thinker's dialectics as much as possible. This is by far the densest and most important part, where the esoteric and strictly metaphysical characteristics of Dugin's thought are exposed. Finally, the last branch is dedicated to ideological praxis as it is manifesting itself in contemporary Russia, casting an objective look at the actual influence of the philosopher in the politics of the Federation. In conclusion, Eurasianism, as well as neo-Eurasianism, are exposed in this thesis as a little-known yet fundamental aspect of the history of political doctrines, which has a real impact on the current domestic affairs in Russia, and in particular dealing with the Russian-Ukrainian crisis and the approach of the relations with the NATO member States
