New instruments for physics research require state-of-the art knowledge, as well as untried technologies. Researchers-engineers and technicians at Dapnia are designing and building, in collaboration with industry, the necessary equipment for physics experiments at laboratories around the world, be they large accelerators, telescopes or satellites.

The cryogenic test facilities for R&D are an important tool used to characterize and qualify phenomena and materials in fields of physics dealing with low temperatures, magnets and accelerators. For the projects, the test facilities allow checking the validity and scope of conceptual innovations. They are also used as a final resource for validating critical components of complex assemblies, or the assemblies themselves. These test infrastructures for superconducting cavities are an integral part of the SUPRATECH platform supported by the Île-de-France region, which includes the facilities of DAPNIA at Saclay and IN2P3 at Orsay.
Performance needs combined with growing complexity of physics experiments require adaptation and technical innovations. DAPNIA is involved in the development of control/command systems that ensure a high level of reliability, availability and flexibility, including advanced communication between heterogeneous systems with an ergonomic interface for users. Magnets and accelerators require advanced technologies with a strong involvement of the DAPNIA as far as instrumentation is concerned. The high level of expertise and experience acquired working on projects of different size using diverse technical means, allows creating tools that will be reusable with the view of performance and ...

Particle accelerators are used to produce high-energy particle beams (elementary particles or different types of nuclei) in laboratories. These beams can be focused on a target (or the centre of a detector, in the case of a collider), providing physicists with intense and controlled collisions for matter science research. DAPNIA/SACM teams design and develop accelerator technologies for present and future experiments, from particle sources to final beam focusing systems, along with copper or superconducting radiofrequency cavities giving energy to the particles.
DAPNIA has acquired significant expertise in the design and construction of superconducting magnets for physics experiments, from quadrupole electromagnets for particle beam control to huge electromagnets used in large detectors. DAPNIA's expertise ranges from laboratory prototyping to technology transfers and monitoring of industrial series production. The ATLAS and CMS detector magnets and the approximately 400 quadrupole magnets constructed for the LHC at CERN are the most representative achievements of the recent period. Beyond the LHC, other systems have recently been developed (e.g. for JLAB and GSI) or are currently being designed (e.g. for the NEUROSPIN and R3B projects). These ... More »
