Job Description
Missions
Within the Nuclear and High-Energy Physics Laboratory, you will be responsible for developing, testing, deploying at the experimental site and, finally, validating the operation of the first autonomous HERON units. The deployment of the first 15 units at the experimental site in the province of San Juan (Argentina) is scheduled for the second half of 2028.
Activity
As a postdoctoral researcher, your activities – which will be highly technical and experimental in nature – will include the following:
- Functional testing and sensitivity measurement of HERON antennas (the active part of the detector)
- Development, testing and validation of the data acquisition chain, and more specifically of methods for the autonomous triggering of antenna data acquisition.
- Development of methods for calibrating the time and amplitude responses of the autonomous antennas.
- Development and validation of methods for reconstructing atmospheric shower parameters.
Your Profil
Skills
You must hold a PhD or equivalent qualification and have expertise in experimental high-energy physics.
You have a strong interest in the development and optimisation of detection techniques; experience of working on test benches and at experimental sites will be a key selection criterion.
Expertise in the radio detection of atmospheric showers would be an advantage, but is not a requirement.
Your Work Environment
The LPNHE is a joint research unit (CNRS, Sorbonne University and Paris Cité) comprising 160 staff, whose research is predominantly experimental in the fields of particle physics and astroparticle physics.
The LPNHE is responsible for the construction of the HERON autonomous antennas. The aim is to deploy, by 2031, a hybrid radio network comprising 24 phased-array stations and 360 autonomous antennas.
Within the LPNHE team, comprising 3 researchers, 2 PhD students and 5 engineers, the work will also be carried out in close collaboration with the HERON team at the IAP.
The main place of work is at the Jussieu site (5th arrondissement, Paris).
Travel to the Nançay Radio Observatory, the HERON experimental site (Argentina) and partner laboratories (in particular Santiago de Compostela, Spain, and Penn State, USA) is to be expected.
