The European X-ray Free Electron Laser (XFEL) will provide as-yet-unrivaled peak brilliance and ultra-short pulses of spatially coherent X-rays with a pulse length of less than 100 fs in the energy range between 0.25 and 25 keV. The high radiation intensity and ultra-short pulse duration will open a window for novel scientific techniques and will allow to explore new phenomena in biology,...

Oral Presentation
The European X-ray Free Electron Laser (XFEL) will deliver 30,000 fully coherent, high brilliance X-ray pulses per second with a duration below 100 fs. This will allow to record diffraction patterns of single molecules and study ultra-fast processes.
One of the detectors under development for the XFEL is the Adaptive Gain Integrating Pixel Detector (AGIPD), which consists of a classical...

Oral Presentation
The European XFEL, currently under construction at DESY in Hamburg, will produce coherent X-ray pulses every 222 ns in a bunch train of up to 2700 pulses. In conjuction with the fast 2D area detectors currently under development, it will be possible to perform X-ray photon correlation spectroscopy (XPCS) on microsecond timescales.
In XPCS experiments using pixel detectors usually the...

Oral Presentation
One of the main advantages of the European XFEL is its fast bunch repetition frequency of 4.5 MHz.
The XFEL will provide bunch trains of up to 2700 bunches every 222 ns, followed by an idle time of 99.4 ms, resulting in a supercycle of 10 Hz and 27000 bunches per second. Correspondingly fast 2D detectors such as AGIPD are being developed. Thiswill allow investigations with various techniques...

Detectors for FELs and other advanced light sources
Oral Presentation
The imaging of soft X-ray images is typically performed with CCDs. However, these have limited readout speed, dynamic range and also require significant cooling to obtain the required signal to noise ratio.
Active pixel sensors (APS) are able to combine faster readout speeds and higher dynamic range with in-pixel intelligence to allow region of interest readout and adaptive gain. To obtain...
