Radiophone Stimminszenierungen im Nationalsozialismus: Eine medienwissenschaftliche Perspektive

Walter Benjamin zufolge hat das mediale Zeitalter der technischen Reproduzierbarkeit von Stimmen und Klängen die Tradierung des Wissens aus ihrem Jahrtausende alten Kreislauf mündlicher Erzählung gelöst, die „Geschichten dem Gedächtnis nachhaltiger anempfiehlt“, als es deren mediale Wiedergabe vermag. Je fesselnder die Erzählsituation von Geschichten ist, „desto größer wird ihre Anwartschaft auf einen Platz im Gedächtnis des Hörenden, desto vollkommener bilden sie sich seiner eigenen Erfahrung an, desto lieber wird er sie schließlich eines näheren oder ferneren Tages weitererzählen. Dieser Assimilationsprozeß“, so fährt Benjamin fort, „bedarf eines Zustandes der Entspannung, der seltener und seltener wird. Wenn der Schlaf der Höhepunkt der körperlichen Entspannung ist, so die Langeweile der geistigen. Die Langeweile ist der Traumvogel, der das Ei der Erfahrung ausbrütet. Das Rascheln im Blätterwalde vertreibt ihn. Seine Nester – die Tätigkeiten, die sich innig mit der Langeweile verbinden – sind in den Städten schon ausgestorben, verfallen auch auf dem Lande. Damit verliert sich die Gabe des Lauschens, und es verschwindet die Gemeinschaft der Lauschenden. Geschichten erzählen, ist ja immer die Kunst, sie weiter zu erzählen, und die verliert sich, wenn die Geschichten nicht mehr behalten werden.

“Please, come in”: Being a charlatan, or the question of trustworthy knowledge

“I am a charlatan, ladies and gentlemen; indeed, I am nothing else than a charlatan. But what I do, it is well done. Please, come in: it is free. I give money to the poor; only the rich have to pay. And when they do, they pay for all.” (Lessona 1884, 84; translated by Irina Podgorny). With these words from the 1860s, Guido Bennati (1827–1898), an ambulant quack from Pisa, introduced himself at his arrival at the market places in the Italian Piedmont. By calling himself a charlatan, Bennati did not disqualify his art. He called his profession by its real name, and he underscored its value: he was a self-styled practitioner in the lower regions of the medical profession who, in Italy, during the time of the Risorgimento, were still licensed to sell some kinds of external remedies and to perform external operations. They seemed to be making themselves heard everywhere. From England to Italy, from France to Spain and the Americas, markets and newspapers were filled with their advertisements and remedies.Fil: Podgorny, Irina. Universidad Nacional de La Plata.

A CLIC Damping Wiggler Prototype at ANKA: Commissioning and Preparations for a Beam Dynamics Experimental Program

In a collaboration between CERN, BINP and KIT a prototype of a superconducting damping wiggler for the CLIC damping rings has been installed at the ANKA synchrotron light source. On the one hand, the foreseen experimental program aims at validating the technical design of the wiggler, particularly the conduction cooling concept applied in its cryostat design, in a long-term study. On the other hand, the wiggler's influence on the beam dynamics particularly in the presence of collective effects is planned to be investigated. ANKA's low-alpha short-bunch operation mode will serve as a model system for these studies on collective effects. To simulate these effects and to make verifiable predictions an accurate model of the ANKA storage ring in low-alpha mode, including the insertion devices is under parallel development. This contribution reports on the first operational experience with the CLIC damping wiggler prototype in the ANKA storage ring and steps towards the planned advanced experimental program with this device

Status of the CompactLight Design Study

International audienceCompactLight (XLS) is an International Collaboration of 24 partners and 5 third parties, funded by the European Union through the Horizon 2020 Research and Innovation Programme. The main goal of the project, which started in January 2018 with a duration of 36 months, is the design of an hard X-ray FEL facility beyond today’s state of the art, using the latest concepts for bright electron photo-injectors, high-gradient accelerating structures, and innovative short-period undulators. The specifications of the facility and the parameters of the future FEL are driven by the demands of potential users and the associated science cases. In this paper we will give an overview on the ongoing activities and the major results achieved until now

CompactLight design study

The H2020 CompactLight Project aims at designing the next generation of compact X-rays Free-Electron Lasers, relying on very high gradient accelerating structures (X-band, 12 GHz), the most advanced concepts for high brightness electron photo injectors, and innovative compact short-period undulators. Compared to existing facilities, the proposed facility will benefit from a lower electron beam energy, due to the enhanced undulators performance, and will be significantly more compact, with a smaller footprint, as a consequence of the lower energy and the high-gradient X-band structures. In addition, the whole infrastructure will also have a lower electrical power demand as well as lower construction and running costs
