Ultrafast electron diffraction at DELTA - commissioning and first results — •Linus Bölte¹, Xijie Wang^1,2, Arne Held¹, Peter Hartmann¹, Carsten Mai¹, Klaus Sokolowski-Tinten², and Marius Milnikel² — ¹Technische Universität Dortmund — ²Universität Duisburg-Essen

Ultrafast electron diffraction (UED) enables the measurement of atomic-scale dynamics with femtosecond time resolution.

At DELTA, a new UED experiment has been commissioned, featuring a 100 kV direct current electron gun and a 3 GHz radiofrequency cavity. Here we present the commissioning process and initial results, demonstrating the potential for simultaneous bunch compression and acceleration.

Keywords: ultrafast electron diffraction; radiofrequency cavity; bunch compression; femtosecond scale resolution
