This thesis addresses in a very new and elegant way several measurements and the extraction of so-called double parton scattering. The new and elegant way lies in the combination of measurements and a very smart extraction of double parton scattering results, which is easy to apply and overcomes many of the technical difficulties of older methods.

We experimentally determined the bulk modulus of (Mg0.8Fe0.2)O ferropericlase across theiron spin transition and in the low-spin phase by employing a new experimental approach. In ourmeasurements, we simulate the propagation of a compressional seismic wave (P wave) through our sampleby employing a piezo-driven dynamic diamond anvil cell that allows to oscillate pressure at seismicfrequencies.

Accurate ab initio calculations on the rotation–vibration spectrum of methyl fluoride (CH$_3$F) are reported. A new nine-dimensional potential energy surface (PES) and dipole moment surface (DMS) have been generated using high-level electronic structure methods. [...]

Liquid microjets are a common means of delivering protein crystals to the focus of X-ray free-electron lasers (FELs) for serial femtosecond crystallography measurements. The high X-ray intensity in the focus initiates an explosion of the microjet and sample. [...]

In laser illuminated dielectric accelerators (DLA) high acceleration gradients can be achieved, due to high damage thresholds of the materials at optical frequencies. This is a necessity in developing more compact particle accelerator technologies. [...]

Over the past decade the production of multi-GeV electron beams from laser-driven plasma accelerators has been successfully demonstrated. However, demanding applications such as compact electron-driven X-ray sources require further improvements on beam energy spread and transverse emittance. [...]

This protocol describes fabricating microfluidic devices with low X-ray background optimized for goniometer based fixed target serial crystallography. The devices are patterned from epoxy glue using soft lithography and are suitable for in situ X-ray diffraction experiments at room temperature. [...]
