Vacancy details

General information


The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.

The CEA is established in ten centers spread throughout France

Job title

Intel HLS firmware development for real time measurement of the luminosity of the LHC H/F


Within the electronics development team (STREAM group) involved in the phase 2 upgrades of the ATLAS detector at CERN, the different tasks of the intern will be:

- Get acquainted with the software toolchain (Intel Quartus and Modelsim) needed to implement and simulate firmware on a Stratix 10 target.
- Get acquainted with the Intel HLS concept and development suite.
- Understand the algorithms to be implemented :
- RTL classical/standard implementation
- HLS Implementation
- Evaluate the resource consumption for each implementation
- Optimize the algorithm,
- Optimize the FPGA resource usage,
- Interface the designed bloc with other existing blocks,
- Document and present progress on work on a regular basis.

Job description

The discovery of the Standard Model Higgs boson in 2012 is undoubtedly a bright success for the Standard Model of particle physics. This discovery however does not bring any answer to many of the questions that are still open in cosmology and particle physics. Among others, there is the nature of dark matter and dark energy, the origin of the Higgs potential, and the fact that the Standard Model does not provide an explanation for the very small masses of the neutrinos. Natural solutions to these problems could come from the existence of new interaction types or new particles.

This is why, since the discovery of the Higgs boson, efforts are focused on the search for new phenomena, beyond the Standard Model. One of the important aspects of the comparison between experimental measurements and theory is the need to normalize as precisely as possible experimental results to theory. This means in practice being able to measure as precisely as possible the luminosity of the LHC. The goal is to reach a precision better than 1% within the next few years. This is a factor two or three better than the precision that has been reached up to now.

LHC experiments are equipped with dedicated luminosity measurement subsystems, and several observables can be used to measure the luminosity. However, the techniques used have various stability and linearity issues, that complicate their exploitation.
