The absolute power of the Linac Coherent Light Source pulses has been measured accurately in the hard X-raybeamline by using simultaneously two detectors:1 an X-ray Gas Monitor Detector (XGMD)2 in tandem witha radiometer.3 From these measurements, we were also able to characterize and calibrate in details our setsof beamline attenuators, in addition to extending an absolute calibration for our beamline intensity monitors.Similarly, we demonstrate that commercial optical power meter has a response in the hard X-ray regime, thatcan be cross-correlated with the absolute power of the LCLS beam..

Operation of X-ray gas monitors at the European XFEL
X-ray gas monitors (XGMs) are operated at the European XFEL for non-invasive single-shot pulse energy measurements and average beam position monitoring. They are used for tuning and maintaining the self-amplified spontaneous emission (SASE) operation and for sorting single-shot experimental data according to the pulse-resolved energy monitor data.

Megapixels @ Megahertz – The AGIPD high-speed cameras for the European XFEL
Ultrafast Imaging and Tracking Instrumentation, Methods and Applications Forum 2018, ULITIMA 2018, Argonne, ILArgonne, IL, USA, 11 Sep 2018 - 14 Sep 20182018-09-112018-09-14 Nuclear instruments & methods in physics research / A Accelerators, spectrometers, detectors and associated equipment Section A 942, 162324 - () [10.1016/j.nima.2019.06.065]  GO
The European XFEL is an extremely brilliant Free Electron Laser Source with a very demanding pulse structure: trains of 2700 X-Ray pulses are repeated at 10 Hz. The pulses inside the train are spaced by 220 ns and each one contains up to $10^{12}$ photons of 12.4 keV, while being $\rm \leq 100$ fs in length.AGIPD, the Adaptive Gain Integrating Pixel Detector, is a hybrid pixel detector developed by DESY, PSI, and the Universities of Bonn and Hamburg to cope with these properties.

Harmonic lasing is an opportunity to extend the photon energy range of existing and planned X-ray FEL user facilities. Contrary to nonlinear harmonic generation, harmonic lasing can provide a much more intense, stable, and narrow-band FEL beam. [...]

This report present the first characterization of the photon beam properties from SASE1 FEL at the European XFEL. Development of the amplification process has been traced from the level of the radiation pulse energy in sub-microJoule level (beginning of high gain linear regime) up to mJ level (saturation regime).

Characterizing transmissive diamond gratings as beam splitters for the hard X-ray single-shot spectrometer of the European XFEL
The European X-ray Free Electron Laser (EuXFEL) offers intense, coherent femtosecond pulses, resulting in characteristic peak brilliance values a billion times higher than that of conventional synchrotron facilities. Such pulses result in extreme peak radiation levels of the order of terawatts cm−2 for any optical component in the beam and can exceed the ablation threshold of many materials. [...]
