About EMIR&A

EMIR&A is the French national network, gathering ion and electron accelerators for studies of the irradiation of materials and molecules and/or for their analysis by using ion beams. It is a federation of platforms providing the scientific community, both public and private, with a set of advanced accelerators and in situ instruments with unique performances, dedicated to irradiation and analysis of molecules and materials.

This network was created in 2009 with the support of CNRS (French National Centre for Scientific Research), and became in 2014 a CNRS Research Federation (FR 3618) under the auspices of three CNRS Institutes, namely Institute of Physics, (INP) Institute of Chemistry, (INC) and Institute of Nuclear Physics and Particles Physics (IN2P3). It was initially known as EMIR (‘Etude des Matériaux sous IRradiation’ – Study of Materials under Irradiation), and became EMIR&A in 2019, to include both ion beam analysis of materials, and irradiation and radiolysis of molecules and materials.
EMIR&A is today one of the 16 existing Research Infrastructures in the field of Material Sciences and Engineering, and included in the national "infrastructure" strategy for 2018.

The EMIR&A facilities are complementary to one another, regarding the accelerated particles, the available energies and the available instrumentation. They are distributed on 6 sites. EMIR&A has been created with the aims to provide access to state of the art accelerator facilities for national and international scientific community, public and private. One primary goal is to foster the links between irradiation and ion beam analysis platforms and encouraging collaborations between research teams.

EMIR&A operates as a large delocalized instrument. Once a year, EMIR&A launches a call for experiment proposals. This call is dedicated to irradiation experiments of materials and molecules and to wide-ranging ion-beam analysis. Pump priming studies and short-duration ion-beam analyses can be proposed throughout the year. All proposals go through an independent scientific evaluation by reviewers and an International Scientific Committee. The accepted experiments are partly financially supported up to now by the facilities, however a user’s participation is required for most of the facilities. The accepted project is carried out thanks to the expertise of specialists from the concerned platform(s).

The EMIR&A International Scientific Committee gives its selection of proposals each year based on the reviewers’ reports, and provides its expertise for the choice of future EMIR&A equipment. This committee is replaced by a third on average every two years.

The EMIR&A Coordination Committee monitors the scientific, strategic and administrative management of the federation.
