Equipment


Several technical teams support the scientific teams. Their mission is to develop and maintain the scientific equipment placed at the scientists' disposal. So the researchers have access to different types of equipment that they use together :
- Administration, documentation, general services
- Analysis, microscopy, images
- Workshops, electronic instruments
- Equipment for calculation and communication
The technical teams count more than 30 persons (engineers, technicians, worker and administration) that assure the management and availability of the equipment and also take care of :
- Development of new experimental devices
- Training activities
- Services and expert reports, especially for SMB.
