The DUNE group at the Laboratoire Astroparticule et Cosmologie (APC) in Paris, France, is receiving applications for a 2-year postdoctoral position. The position will develop in the frame of the Deep Underground Neutrino Experiment (DUNE), an international collaboration with more than a thousand members and more than 30 countries involved. The project is hosted at Fermilab and has a strong collaboration with CERN. France is heavily involved, with researchers from APC, LPSC, IJCLab, LAPP, IPNL and CEA. The French DUNE collaboration has recently been awarded with a TGIR program (which stands for “very large research infrastructures”) form the French ministry of science with significant financial support.
DUNE is carrying out an intense prototyping campaign to develop a new detector concept, a single-phase LArTPC using PCB printed boards instead of wires as anodes. This new proposal includes a novel design of the Photo-Detection system, with Silicon PhotoMultipliers (SiPMs) embedded in the cathode and cage surfaces. A small-scale prototype will be assembled during 2021, while a large 300-ton prototype is envisaged for 2023. The position concerns the necessary developments in the upcoming years for the construction, operation and data analysis of these prototypes.
The DUNE group at APC has 4 faculty members and a PhD student, and has been mainly involved in the evaluation of the alternative, dual-phase  LArTPC technology, including analysis of the data collected by the prototype at CERN (ProtoDUNE-Dual Phase), simulations and optimisation of the track reconstruction algorithms. The group has also developed a prototype of the readout electronics for the photo-detection system. In line with these efforts, the group continues to work in the improvement of the performance of the track reconstruction algorithms, and analysis aimed at demonstrating the performance of a full-scale detector. Additionally the group works closely with colleagues at Fermilab and APC engineers to develop a new transmission system for the signals of the SiPM detectors.


The successful candidate will participate in both the analysis and hardware activities of the group, as well as in the installation and running of the prototypes at CERN.

The candidates are invited to submit a motivation letter and a CV using the CNRS job portal, https://emploi.cnrs.fr/, and have at least 2 letters of recommendations sent directly by the chosen referrants to Thomas Patzak, patzak@apc.univ-paris7.fr.


- Candidates should have a PhD in either particle or astroparticle physics. Experience with particle detectors, Monte-Carlo simulations and/or data analysis is desirable.
- Candidates should have a maximum of 2 years working experience since their PhD.
- English language

Work Context

The AstroParticle and Cosmology (APC) laboratory is a Joint Research Unit (UMR) created in 2005. The APC brings together around 75 permanent researchers, and around fifty engineers, technicians and administrative staff. Including non-permanent staff (doctoral students, postdoctoral fellows, foreign visitors), some 200 people form this structure, managed in addition to the University of Paris (UP), by the CNRS (represented by three of its Institutes: mainly the 'IN2P3, but also INSU and INP), CEA (DSM / IRFU) and the Paris Observatory, and CNES.

Constraints and risks

The post doctoral student will be required to go on a mission in France and abroad. No particular risk is to be expected.

Candidates are invited to submit, in addition to their cover letter and CV, two reference letters.
