Reference : UAR3266-VIRLEF-056
Nombre de Postes : 1
Workplace : CAEN
Date of publication : Thursday, January 19, 2023
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 1 April 2023
Proportion of work : Full time
Remuneration : 2800 € à 3900 € Gross monthly depending on experience
Desired level of education : 5-year university degree
Experience required : 1 to 4 years


The Postdoctoral Researcher will play a leading role in the development of new techniques and processes to produce high-quality, thin targets sustaining very intense heavy ion beams.
She/He will work within the framework of the European EURO-LABs project whose aim is to improve the service of the participating European Research Infrastructures for their internal and external users. He/She will be a member of the collaborative partnership involved in the above-mentioned project and international collaboration.


The main tasks of the postdoctoral fellow will be related to the development of the thin layer laboratory at GANIL with the final goal to deliver reliable targets for experiments
The candidate will be in charge of the research and development of some specific targets (lanthanides or metals) to meet the requested specifications (thickness, geometry, performance under irradiation, compatibility with backings..). Regarding the selected target and its specifications, he/she shall contribute to activities such as:
- conduct studies on existing methods and their limits, on materials with their properties and behavior with other materials (interface issues, adherence…)
- identify and put in place innovative materials and methods of fabrication and characterizations
- investigate in detail, employing advanced analysis methods, the resulting targets before, during and after irradiation with quantification and identification of contaminants, damages, areal density, homogeneity etc
- optimize protocols of fabrication

In the framework of the research activity, the candidate will participate in the implementation of new equipment in the thin layer laboratory. This laboratory will be equipped with 4 new systems of deposition under vacuum in the coming years.

These devices are based on the principle of evaporation, sublimation or sputtering of material using resistive or electron beams heating and focused ion beams.
The candidate will be involved in the definition of one of these systems.

The candidate will be responsible to develop the fabrication process of high-quality targets, and apply the optimal protocols with the goal to obtain reproducible and reliable results. This protocol will be established by conducting analysis using existing on-site instrumentation or in other laboratories of the international target laboratory network.
These activities will lead the candidate to report results of technical development and methods, target analysis and performance in workshops, conferences, and various meetings related to targets or research programs.
Moreover, within the EURO-LABS project, the candidate will be in charge of the requested deliverable of the subtask “Target service”. It consists of the creation of a database, publicly available, containing the information about the preparation and characteristics of available targets and those newly developed in various laboratories within this subtask. The candidate will collect information on the state-of-art of technologies in Europe, expertise of in-house targets etc.


Main skills :

- Sound knowledge of chemistry, engineering, physics or a related field
- Comprehensive skills in the use of basic laboratory equipment and techniques

Know-how :
- A good experience in thin layer preparation and characterization with vapor deposition, rolling, electrodeposition, and thermal reductions would be advantageous.
- The candidates should demonstrate the ability to work in a research environment, prepare research results for publication and for presentation at scientific meetings.
- Organizational and communication skills, teamwork capability
- Fluent English in spoken and written
Soft skills :
• Relational ease to interact effectively and tactfully in a team on multi-disciplinary projects to successfully develop effective working relationships
• Ability to model GANIL's regulatory and quality requirements: Impact, Safety, Respect, Integrity,….

Work Context

The Grand Accélérateur National d'Ions Lourds is a national research infrastructure based on the use of ion beams. Its fields of research are fundamental research in nuclear physics and nuclear astrophysics, the study of materials under irradiation and nanostructuring, molecular collisions and the interstellar medium, radiobiology and innovative techniques for imaging and therapy of certain cancers.
GANIL (about 270 people) is located in France, in the city of Caen, in Normandy. Le GANIL is located on the future site EPOPEA science and innovation park of the urban community Caen la Mer. It is managed jointly, within an Economic Interest Group (GIE) by the Commissariat à l'Energie Atomique (CEA/DRF) and by the Centre National de la Recherche Scientifique (CNRS/IN2P3). As a national research infrastructure, GANIL serves the national, European and international scientific community of about a thousand users.
The candidate, recruited on a one year fixed-term contract, will be attached to the DEtection and Laser for Physics (DELPH) group made up of ~20 people (engineers, technicians, postdoc, PhDs). This group is integrated into the Physics Division where the Research Activity Group (GAR) is also located.
The candidate will work with a team composed of one technician responsible of this laboratory, one engineer and a researcher.
The fellow will be trained by the “targets” GANIL team and will reinforce some skills in laboratories involved in the EURO-LABS project.
Periods of travel within France and abroad should be expected

The project of the fellow forms part of GANIL-SPIRAL2's scientific program and of EURO-LABS (“European-Laboratories For Accelerator Based Science », https://web.infn.it/EURO-LABS/), a four-year project funded in the Horizon Europe program of the European commission.

The contract agent recruited by the CNRS will benefit from a number of holidays linked to the derogatory status of the GIE GANIL of the order of 53 days (32 CA and 21 JRTT) with a weekly work rate of 40 hours per week, i.e. 8:25 a.m. – 5:10 p.m. with 45 minutes of meridian break, and benefits of social action for CNRS agents of GANIL.

Constraints and risks

As GANIL is classified as a Basic Nuclear Installation (BNI), the position is eligible for specific work constraints related to potential exposure to ionizing radiation.
The candidate must be authorized to work in a supervised and controlled area in compliance with the regulations and procedures applicable to nuclear security and safety.
