Within the framework of the EICROC project (development and characterization of a large size ASIC, 32x32 channels, dedicated to the readout of AC-LGAD sensors), the research activity of the post-doctorant focuses on a technical contribution to the international ePIC (electron Proton-Ion Collider experiment) collaboration associated with the construction of the future Electron-Ion collider (EIC : Electron Ion Collider, New York, United States). The successful candidate will work within the “JLab-EIC” hadronic physics team of the “High Energy Physics” (PHE) pole of the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab) under the supervision of Dominique Marchand, scientific coordinator of the EICROC project involving researchers (2), engineers (2) and technicians from IJCLab, OMEGA (Organization for Advanced General Micro-Electronics, 4 people), from the department of electronics, detectors and computing for physics (DEDIP, 1 person) of the CEA-Saclay/Irfu and Brookhaven National Laboratory (BNL, New York).

The work will consist in contributing to the development and the characterization of iterations of ASICs dedicated to the readout of AC-LGAD type sensors, capable of very good timing (~30 ps) and spatial (~20 um) resolutions, which will be exploited by several detectors in the ePIC experiment, notably the Romans Pots. The hired researcher will work within a collaborative environment and may be required to participate in the supervision of PhD or Master students.


The recruited person will exploit the existing test bench developed for the EICROC0 protype (4x4 channels) to characterize the electronic response of each channel, to evaluate the jitter, the crosstalk and to determine the charge sharing ratio of the system (EICROC0+AC -LGAD) by using a Beta source and an infrared laser test bench. Script development in Python will be necessary to control ASIC parameters, to automate data collection and to record data for analysis. The successful candidate may also be involved in simulation work (GEANT4). The results obtained will be the subject of progress reports (presentations, reports) intended for the EICROC international collaboration and dissemination of the results among the ePIC collaboration. These activities will also be presented in dedicated international workshops/conferences and, depending on the progress of the work, will result in publication.


- PhD in experimental subatomic physics,
- Desired experience in scientific instrumentation / particle detection,
- Proven skills in data analysis and modeling (GEANT4),
- Assertive proficiency in Python, C++ (or C) programming languages, and in the ROOT software suite,
- Autonomy, organizational capacity and ability to report with pedagogy,
- Ability to work within a team,
- Fluency in English (oral and written) required,
- Proven ability to promote research: oral presentations and publications.

Contexte de travail

The Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab, https://www.ijclab.in2p3.fr/) is a mixed research unit under the governance of the CNRS, the University Paris-Saclay and the University Paris Cité. IJCLab is located on the Orsay campus, 20 km south of Paris, accessible by RER B in 35 minutes.
IJCLab brings together about 700 people and is organized into 7 scientific poles (nuclear physics, high energy physics, astroparticles/astrophysics and cosmology, energy and environment, physics for health, accelerators).
The structure has very significant technical capacities (around 280 engineers and technicians) in all the major fields required to design, develop and implement the experimental devices necessary for its scientific activities: mechanics, electronics, IT, instrumentation, technology. acceleration and techniques for biology. These technical strengths represent a key asset for the design, development and the use of the necessary instruments (accelerators and detectors). The presence of research infrastructures and technological platforms gathered on the laboratory site is also a major asset. Finally, around 90 engineers and technicians from administrative and support departments work alongside with scientists and technical personnal.
The selected person will join the JLab-EIC team which includes around 15 persons (6 CNRS researchers, doctoral and post-doctoral students). The Jlab-EIC team is part of the high energy physics (PHE) pole which accounts for about hundred members.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

The successful candidate will be based primarily at IJCLab. As part of the international ePIC collaboration, travel abroad, particularly to the United States, is expected for work meetings, beam tests and workshops/conferences attendances.
