I am a permanent scientific staff member in the
Experimental Particle Physics group of
within the Department of Physics
at the University of Siegen, Germany.
ATLAS is one of the four major experiments at the Large Hadron
Collider (LHC) at CERN, the European Particle Physics Laboratory
As a member of the ATLAS collaboration
I am involved in the following activities:
- Construction and operation of the ATLAS pixel detector.
We have assembled and tested about 330 modules for
this detector in our local labs.
- Preparation of data analyses involving decays of
B-mesons (B-physics). Our group is studying
the measurement of Bs0
oscillations at ATLAS using
the Bs0 →
in close collaboration with the particle physics
group at the University of Innsbruck
and prepares a measurement of the b cross section
at large values of transverse momentum. The later
makes use of our expertise in b-tagging tools.
- Preparation of data analysis tools for tagging of
jets containing B-mesons ("b-tagging").
Distributed computing on the Worldwide LHC Computing
Grid (WLCG) is essential for being able to analyze
the amount of data expected from the LHC experiments.
As part of the German e-Science initiative D-Grid our group
is member of the High Energy Physics Community Grid (HEP-CG)
project. In collaboration with the group of Prof.
Wismüller of the Department for
Electrical Engineering and Informatics
and the Center of Information and Media Technology (ZIMT)
a Result Monitoring and Online Steering Tool (RMOST) is
being developed. Our group also maintains a local
Grid computing installation as part of the WLCG.
The next worldwide project in accellerator-based particle
physics will most likely be an International Linear Collider
(ILC). As part of the Helmholtz Alliance "Physics on the
the Terascale" and being a partner in the EUDET program,
our group is involved in the development of a
Time Projection Chamber (TPC) for an ILC experiment.
We are investigating read-out options involving GEM foils
for the gas amplification with a local test chamber.
