Terahertzblitze ermöglichen exakte Röntgenmessungen

Wissenschaftler entwickeln eine Methode, um Prozesse mit hochintensiven ultrakurzen Röntgenpulsen bis auf wenige Femtosekunden genau zu untersuchen

(PresseBox) (Hamburg, )
Viele physikalische und chemische Vorgänge laufen in extrem kurzer Zeit und auf extrem kleinen Längenskalen ab, in der Regel in Zeiten von billiardstel Sekunden und auf Längen von milliardstel Metern. Um solche Phänomene zu untersuchen, nutzen Forscher intensive ultrakurze Röntgenblitze. Denn aus der Fotografie weiß man: Je schneller ein Vorgang abläuft, desto kürzer muss die Belichtung sein, die diesen sichtbar macht. Forscher erzeugen solche intensiven, ultrakurzen Röntgenblitze in großen Forschungsanlagen, sogenannten Freie-Elektronen-Lasern. Eine in Hamburg und Berlin entwickelte neue Methode ermöglicht es nun die Zeitauflösung dieser Großgeräte voll auszureizen. Die Forschergruppe von DESY, HZB, der European XFEL GmbH und des
