Physics analysis with the CMS experiment

CMS Analysis office Oliver Pooth

Join us investigating new phenomena of elementary particles and study interesting physics at the frontier of current knowledge. In the field of object-oriented software development, you will learn Monte Carlo methods, techniques of statistical data analysis and worldwide distributed computing on the Grid in the context of a modern high-energy physics experiment.

CMS detector development for the running at HL-LHC

For the operation of the CMS experiment at the scheduled HL-LHC, the inner silicon tracking detector of CMS will be renewd. The work for installation in the year 2023 is already at full swing. We are working on so-called 2S detector modules whose sensitive area is made from two silicon strip sensors. An important aspect of the work will be wirebonding, the electrical connection between the silicon strips and the readout electronics.




Detector development with SiPMs

Testbeam Jülich 2014 Oliver Pooth

We concentrate on the development and optimization of detectors, that are read out with SiPMs. Our focus is on the detection of highly energetic muons. The detectors originally developed for the CMS experiment have led to interesting spin-offs, e.g. the detection of fast neutrons or a lab class experiment on the roof of the physics center for the detection of cosmic air showers.

Grid computing for the CMS experiment

Computer Andreas Nowack

Annually, the CMS experiment records several petabytes of measured and simulated data, which are processed using grid computing in the Worldwide LHC Computing Grid (WLCG). The WLCG consists of approximately 150 computing centers with more than 460,000 processor cores and more than 254,000 terabytes of disk space, which are globally networked via the Internet. Within the WLCGs, physicists can access the data of the CMS experiment and evaluate them.

Our Institute operates a large computer cluster with more than 5,200 processor cores and over 3,000 terabytes of disk space. These resources are part of the WLCGs.

Radiography with fast neutrons

Aus der Detektorentwicklung für CMS heraus hat sich ein spannendes Spin-Off Projekt entwickelt. In enger Zusammenarbeit zwischen dem Institut für Nukleare Entsorgung und Techniktransfer, dem III. Physikalischen Institut B sowie der AiNT GmbH werden innovative Detektorkonzepte für die schnelle Neutronenradiographie untersucht. Ziel ist eine kompakte Laboranlage für die zerstörungsfreie Charakterisierung großvolumiger Objekte, z.B. Bohrkerne oder Behälter für radioaktive Abfälle.

Untersuchung der Neutronik einer Anlage für die Prompt-Gamma-Neutronen-Aktivierungsanalyse (PGNAA)

In Zusammenarbeit zwischen der AiNT GmbH und dem III. Physikalischen Institut B wird eine Masterarbeit angeboten, in der die Neutronik einer PGNAA-Messeinrichtung für die zerstörungsfreie Ermittlung der elementaren Zusammensetzung unterschiedlicher Proben untersucht werden soll.
