For more than 30 years, IRELEC has been involved in the design and manufacture of high technology equipment for demanding applications, such as Large Research Infrastructures (particle accelerators, power lasers, etc.) and Medical Research Centers.

Its excellence is reputed in France as well as worldwide: IRELEC supplies and maintains in operational conditions equipment all over Europe, in the Americas and in Asia.

IRELEC's 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's Main Product Lines:

With over 20 years of experience, ITOPP (formerly ITHPP) has become the French leader in high pulsed-power and high-power microwave technologies. 

Driven by customer specifications, ITOPP designs and manufactures adapted and highly innovative systems linking these technologies to scientific research and also to civil and military applications. 

High Pulsed-Power technologies allow for the amplification of electrical power delivery  over a shorter burst period. 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 one hundred Gigawatts.

High-Powered Microwaves are very highly charged electromagnetic pulsations capable of disturbing and even destroying electronic components used in today's increasingly complex systems. The interest in these high-powered microwaves are due to the vast array of uses, varying from more classic uses (such as Radar) to more advanced technologies, such as those used  in Electronic Warfare.
