LHCb is a high-energy particle physics experiment at the Large Hadron Collider at CERN. Its main goal is to perform high-precision measurements of CP-symmetry violating processes in the decay of B-mesons. These measurements will permit important tests of the Standard Model of high energy particle physics. CP violation also plays in important role in cosmology, where it is required in order to explain the observed dominance of matter over anti-matter in our universe.

Our group has played a leading role in the design and construction of the LHCb Silicon Tracker. We are now responsible for the operation of this detector and actively involved in several physics analyses.

CTA is an initiative to build a next generation ground-based gamma-ray Cherenkov Telescope Array, which will provide the deepest ever insight into the non-thermal high-energy universe. It foresees a factor of 5-10 improvement in sensitivity in the current energy domain of about 100 GeV to some 10 TeV and an extension of the accessible energy range to well below 100 GeV and above 100 TeV.

Our group contributes with the development of an active mirror control system that will be crucial for an accurate positioning of the many mirror segments that constitute the primary mirror of the telescopes. Furthermore we work on the development of an FPGA based digital readout for the photon detectors.

H1 was a high energy physics experiment at DESY, Hamburg, studying deep inelastic scattering of electrons and protons at HERA. It stopped data taking in 2007 but the analysis of the collected data still produces new results.

Our group has been involved in various physics analyses, concentrating especially on rare and exotic processes as well as the production of isolated photons. Furthermore, important components of the H1 detector were developed at our institute: a five-layer multi-wire proportional chamber and a fast z-vertex trigger system.
