Offer Description

Czech Technical University in Prague (CTU) now offers a new fellowship program, the CTU Global Postdoc Fellowship. This new and attractive two-year fellowship-program offers excellent researchers who have recently completed their PhD the chance to continue their research career at CTU. Fellows receive a two year fellowship and become members of a team led by a mentor. The fellowship aims at external international scientists who are currently conducting research abroad. Applicants must have completed their PhD within the last seven years (eg. 2016 or later). The fellowship aims at authors (co-authors) of three or more publications in a journal with IF.

A network of ~13 two-layer Timepix3 pixel detectors have been installed in ATLAS with the aim of measuring luminosity and providing information about the radiation field composition at different locations in the ATLAS cavern.

Timepix3 is a cutting-edge hybrid pixel detector with 256 x 256 pixels each of area 55 x 55 µm2. The pixelated sensor is coupled to the readout ASIC, which provides the information of the time-of-arrival (particle interaction time, precision ~2 ns) and the time-over-threshold (energy) in each pixel. Ionizing radiation interacting in the sensor is then seen as imprints in the pixel matrix with characteristic shapes depending on the particle of interest. With the two-layer approach, we further facilitate the separation of charged and neutral particles and improve impact angle determination.

The time resolution of the devices and synchronization with the LHC orbit clock allows to resolve the bunch structure of the LCH beams, so that we expect to be able to measure the luminosity bunch-by-bunch, for the first time with hybrid pixel detectors. The capability to separate different particle classes shall be exploited to reduce the systematic errors of the luminosity measurement.

Comparison of measured particle fluences and ATLAS simulations will be used to assign safety factors for radiation dose estimation and improve the understanding of radiation tolerance needed for detectors at the HL-LHC.

Within the project,

  • you will be responsible for the analysis of data taken with ATLAS-Timepix3 and represent the team in the offline luminosity meetings and the radiation simulation group of the ATLAS experiment;
  • you will develop improved analysis methodology and define tasks for your coworkers;
  • you will be responsible for the preparation of publications and conference contributions.
  • The position will help you to significantly improve your research profile by increasing leadership and mentoring skills. You will work in an international and interdisciplinary team with coworkers at different stages of the career.

    You will work in the department of “Electronics and Software” of IEAP CTU, which is a leading group in the development of pixel detector readout systems, related detector control software and novel analysis methodology. The latest activities are here or in a compact form here.

    Education Level

    PhD or equivalent


    You should have a Ph.D. in physics, are interested in data analysis and not scared of large data sets. Fluent English is required. Programming skills in C++, knowledge of ROOT, simulation in Geant4 and experience with leading a small team are not needed but an advantage. You will profit from knowing your way in large collaborations (ATLAS).
