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.

For more than 30 years, IRELEC designs and manufactures high technology equipment for demanding applications, such as large research infrastructures (particle accelerators, power laser …) and medical research centres.

The reputation of its excellence has been affirmed in France as well as worldwide: IRELEC supplies and maintains in operational conditions equipment all over Europe, in Americas and in Asia.

IRELEC commitment to its customers is based on its ability to adapt robust solutions to their specific constraints, thanks to IRELEC expertise in high precision mechanical engineering, robotics, ultra-high vacuum technologies and cryogenics.

IRELEC main product lines:

• Opto-mechanical systems for X-ray beam transport and conditioning
• Robotic systems intended to complex processes, such as biological samples manipulation in cryogenic environment
• Test benches (power electronics characterization, detection of pollution by nanoparticles, control of magnetic structures…)

PMB specialises in the assembly of dissimilar materials by vacuum brazing. It makes complex mechanical components for global medical equipment industries. These "metal/metal" or "ceramic/metal" assemblies are integrated into X-ray tubes for scanners, or in radiotherapy machines or in medical implants in the form of pressure seals.

It also develops products used in scientific research, defence, space and nuclear.

It has a production site in France and a second in the Maghreb through its subsidiary PMB Tunisia, offering its main clients a reliable supply for optimised cost.

ADR designs, produces and sells high-precision ball bearings in a wide range of sizes (from 1 mm bore to 330 mm outside diameter).

These highly sensitive bearings are found in sights, gyrostabilised systems, optoelectronic and avionics equipment, infrared pointers, encoders, motors, etc.

ADR develops and offers integrated technical solutions adding many functions to the bearings within the context of its stated strategy as a subsystems developer.

ADR also designs and produces actuators specifically adapted to highly complex systems.
