Postdoctoral Researcher within the CMS Experiment

Scientific environment
The Institute of High Energy Physics (HEPHY) of the Austrian Academy of Sciences in Vienna,
Austria, performs a rich experimental particle physics program participating in accelerator and
non-accelerator based experiments. The institute has a major involvement in CMS at CERN and
in the Belle / Belle II experiment at KEK. A new experimental group working on direct Dark
Matter detection is currently built up. A theory group completes the research profile of the

Involvement in CMS
HEPHY is one of the founding members of the CMS Collaboration. We have been strongly
involved in the design, construction and operation of two of the major components of the
experiment: the trigger system and the tracking detector. Our experience in building silicon
based detectors, the construction of FPGA based hardware and development of the appropriate
firmware together with our expertise in reconstruction algorithms and its implementation
in software allow us to play a leading role within the collaboration.

Contribution to the CMS upgrade at HEPHY
We are providing major contributions to the upgrade of the tracking system of CMS. Our main
involvement will be in the development and production of silicon sensors and the associated
detector modules as well as the development of algorithms for track reconstruction.
Furthermore, we have recently joined the High Granularity Calorimeter (HGC) collaboration
within CMS. We will contribute to the development and production of the silicon sensors for this
new type of detector.

We work in close collaboration with a major European semiconductor manufacturer based in
Austria. Together with our industrial partner we are currently developing silicon sensors for
charged particle tracking. They are envisaged to be used in the CMS Tracker and the HGC as well
as in other scientific experiments and in medical applications.
At the same time, the group is involved in several national and EU funded projects.

2 What we are looking for:
HEPHY is looking for a postdoctoral researcher to join our silicon sensor development team. The
successful applicant is expected to play a leading role in the sensor development for the HGC and
shall support all hardware activities within the group. Key activities are:
• Active participation in working meetings of the HGC collaboration
• Design and simulation of the new HGC silicon sensors with our industrial partner
• Neutron irradiations at the TRIGA Mark II nuclear reactor in Vienna
• Development and construction of test setups for sensors
• Development of quality assurance strategies for the series production of sensors
• Supervision of Bachelor, Master and PhD students within the working group
• Contributions to the operations of the CMS experiment
Applicants shall have a PhD within the field of experimental particle physics. We expect in-depth
experience with silicon particle detectors and a general understanding of electrical engineering
and information technologies.

What we have to offer:
• Interesting and diversified work embedded in a motivated team of experts
• Participation in the CMS experiment including full authorship of future CMS publication
• Regular working meetings at CERN and at collaborating institutes with the possibility of
longer research visits
• Attendance of international conferences and schools
• Close collaboration with a major semiconductor company
