With over 20 years of existence and experience, ITHPP has become the French leader in high-pulsed power and high-power microwave technologies.
Driven by customer specifications, ITHPP designs and manufactures highly adapted and innovative systems linking the technologies to scientific research, civil and military applications.
High Pulsed Power technologies allow the amplification of electrical power delivery over a shorter burst duration. Since energy is the product of power over time, by maintaining a constant flow of energy and reducing the duration of the pulse it is possible to achieve powers in excess of a hundred Gigawatts.
High Powered Microwaves are very highly charged electromagnetic pulsations capable of disturbing and even destroying electronic components used in increasingly complex systems. The interest in these high powered microwaves are due to the vast array of usages, varying from more classic usages (Radar types) to more advanced technologies, such as those used in Electronic Warfare.

Power lasers
ALSYMEX and ITHPP are involved in the Megajoule Laser (LMJ) programme. They offer innovative solutions and services that meet strict requirements.
As such, ITHPP is in charge of providing the switching functions of Megajoule laser energy benches.
ALSYMEX, through its involvement in many subassemblies of laser chains, is one of CEA's main partners:
- design, production, clean room assembly and on-site integration of amplifying sections, laser transport lines and certain subassemblies of the frequency conversion system,
- manufacturing of adaptive mirrors and protective panels of the experimental sphere, etc.
ALSYMEX also maintains in operational condition various equipment parts of the laser chains and of the experimental hall, and carries out anti-reflection treatments for all LMJ optics (SOL GEL).
This unique expertise, developed within the context of this key project of the French nuclear simulation programme, is also used to respond to the other demands of large high-power laser projects. ALSYMEX is therefore involved in the European ELI project, in particular in the Romanian pillar, being responsible for:
- design, manufacture and on site installation of a interaction chamber between high energy electrons and photons to generate gamma rays;
- design, manufacture and on site installation of key components of 10 PW laser beam transport systems.

Particle accelerators
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 programmes.
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 programme, constructed in Hamburg within the context of a European collaboration. The company was responsible, in collaboration with CEA, for the assembly of the one hundred cryomodules of the accelerator.
The assembly operations were organised 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 robotised 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.
