À propos d’ITOPP
Your Title Goes Here
ITOPP (formerly ITHPP) designs, develops, manufactures, tests and operates Pulsed Power systems for Research, Defence and Industry.
Based on client specifications, ITOPP develops, designs manufactures and tests pulsed power systems to study the behavior of materials placed under very high pressures, test lightning vulnerability, carry out hyper-speed impacts, study ultra-fast physical phenomena (flash radiography), and contribute to nuclear fusion experimentation. ITOPP also masters the design and development of high-powered microwave equipment.
Since its creation in 1997, ITOPP has been supporting major defense players in the development of pulsed power systems. Its long-standing partnership with historic clients such as CEA (Commissariat à l’Énergie Atomique) and DGA (Direction Générale des Armées) has helped establish ITOPP as a key player in the pulsed power field.ITOPP’s international expansion is closely tied to this shared legacy with these organizations.
ITOPP is composed of a highly skilled team with multi-technical expertise across a wide range of fields, including plasma physics, electromagnetism, electronics, and power electronics. These diverse competencies are supported by cutting-edge technical resources and specialized equipment, all available on-site at ITOPP. This infrastructure ensures a high level of responsiveness in project implementation. Additionally, in-house mechanical and IT expertise is leveraged to develop complete systems. Thanks to its comprehensive know-how and advanced resources, the company has gained significant expertise in managing innovative projects.
ITOPP is a subsidiary of the ALCEN Group and is certified to ISO 9001, ISO 14001, and ISO 45001 quality standards.
Technologies
Pulsed power technologies facilitate the amplification of electric power delivered by a system through a significant reduction of the duration of the pulse. As energy is the product of multiplying power by time, it is possible through the conservation of energy and by decreasing the duration of the pulse to reach extremely high powers.
As such, ITOPP creates systems capable of delivering currents of several million amps, voltages of several million volts for durations that can be less than one hundred billionths of a second. The power produced can therefore exceed one hundred gigawatts.
In general, Pulsed Powers are able to meet needs for research in physics, particularly nuclear physics, but increasingly also for industrial applications.
Energy banks are in a way the simplest explanation of such systems and generate very high currents (up to several millions of amperes). As of the 1920’s, the development of Marx generators has made it possible to obtain several million volts. Since then, new concepts have emerged, such as IVAs (Inductive Voltage Adders) or LTDs (Linear Transformer Drivers).
Mission
Through innovation in the Pulsed Power field, we wish to make a lasting contribution to our local economy, to facilitate the development of our contributors and their families and to preserve the environment.
We provide the conditions to stimulate innovation.
In order to meet the challenges of our mission, we have defined our values as follows:
- Technical excellence: Through long-standing collaborations with multiple demanding partners, ITOPP has acquired invaluable cutting-edge knowledge and know-how in the Pulsed Power field.
- Learning: It is by devoting time to learning and creativity that we set the conditions for an innovative environment.
- Flexibility: Implementing an agile project-based approach allows us to strike a balance between human competencies and technical knowledge to successfully deliver our projects.
- Initiative: Because innovations are not possible without initiative, at ITOPP, we encourage the emergence of new ideas and concepts.
