General information

CEA (logo)

Organisation

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

Development of a new scintillator for high-speed X-ray imaging (M/F)

Subject

The CEA List is working on the development of a dedicated measurement chain for monitoring experiments involving Rapid Transient Phenomena (RTP) in X-ray imaging. The challenge is to create a measurement system that can be integrated into laboratory settings for a wide range of RTP experiments, with performance levels approaching those of a synchrotron. An initial goal is to achieve a temporal frame rate exceeding 1 kHz, with a spatial resolution range of 300–30 µm.

Several areas of focus address different components of the measurement chain: the X-ray source, image post-processing algorithms, and the detector. This internship will specifically concentrate on the detector, particularly its scintillating component.

Job description

Join Us for an Internship!

As an intern at CEA, you will have the opportunity to work in a world-renowned research environment. Our teams consist of passionate and dedicated experts, providing an ideal setting for learning and collaboration. You will have access to cutting-edge equipment and top-tier research resources to successfully carry out your missions. T


Job Description:

The main objective of this internship is to develop the shaping of plastic scintillator material into a pixelated matrix corresponding to the detector (300–30 µm). To achieve this, the intern will manufacture the plastic scintillator as a thin film and conduct bonding and cutting experiments to obtain the desired structure. Various formulations of plastic scintillator will be tested to optimize stopping power and the temporal properties of the scintillation. Experimental campaigns using X-ray tubes are also planned.

The intern will build on established laboratory protocols and will have the opportunity to explore different compositions of plastic scintillator. The internship will take place across two laboratories: fabrication will be carried out at LCIM (Laboratory for Sensors and Instrumentation for Measurement), and radiography testing will be conducted at LIMTEC (Multi-Technique Instrumentation Laboratory).
