Whether for fundamental research (nuclear and particle physics) or applied research (synchrotrons and neutron sources) or industrial applications (medical and non-destructive testing), ALSYMEX, IRELEC and PMB are involved in design and manufacture for major particle accelerator programs.
ALSYMEX
ALSYMEX designs and manufactures mechanical components and subassemblies that comply with restrictive specifications in terms of dimensions, precision, pressure and cleanliness.
For example, ALSYMEX is involved in the X-FEL X-ray free-electron laser program, constructed in Hamburg within the context of a European collaboration. The company was responsible (in collaboration with the CEA) for the assembly of the one hundred cryomodules of the accelerator.
The assembly operations were organized around eight special workshops, some in an ISO 4 ultra-clean environment, combining assembly, welding, inspection, vacuum, laser tracker metrology and handling expertise.
IRELEC
For over 25 years, IRELEC has designed and manufactured highly reliable optomechanical components for soft and hard X-ray beamlines of synchrotron light sources around the world (France, Germany, England, Spain, Sweden, USA, China, Australia, etc.): high-stability modular mirror systems, Kirkpatrick-Baez systems, LAUE monochromators, dynamic mirror benders, beam attenuators, micro-ovens for tomography experiments and X-ray diffusion.
IRELEC also designs and manufactures robotized systems for transferring and handling frozen biological samples (macromolecules).
PMB
PMB designs and manufactures a wide range of components and subsystems at the heart of electron or hadron accelerators, whether these are hot or supraconducting:
- Beam Position Monitors (BPM) used to measure and check the exact position of the electron beams. In addition, PMB manufactures SMA type penetrations
- Electron guns generating the particles that are then accelerated
- Kicker ceramic vacuum chambers
- Power couplers for injecting the RF power necessary for operation of the supraconducting cavities while guaranteeing the thermal and atmospheric transitions between these and the outside environment
- RF windows ensuring separation between the ultra vacuum at the core of the accelerator and the outside environment while guaranteeing propagation of the RF power necessary for operation of the cavities
- Copper accelerating sections for linear accelerators (frequencies between 3 and 9 GHz)
PMB designs, manufactures and assembles all of the components of the beam lines in particle accelerators. The company also activates the gun and performs the high-frequency conditioning.
