Elementary Particle Physics at H1, LHCb and CTA

|
H1 is a
large high energy physics experiment at DESY, Hamburg, studying deep
inelastic scattering of electrons and protons at HERA.
Our group is
strongly 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 have been developed at our
institute: a five-layer multi-wire proportional chamber and a
fast z-vertex trigger system.

|
LHCb is
a high-energy particle physics experiment that is currently
under construction and will operate 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 and is involved in simulation studies to determine
the physics reach of LHCb.

|
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 well below 100 GeV and to above
100 TeV. Implementation of first prototype telescope(s)
of the system could start in 2010 after a period of a detailed
design study and optimization, site evaluation and production
of industrial prototypes of components.
Our group contributes
with the development of active mirror control that will be
crucial for an accurate positioning of the mirror segments
that constitute the primary mirror of the telescope.
Furthermore we work on the development of an FPGA based
trigger-less digital readout for the photon detectors.
