Trusted to deliver for more than 70 years

Since the 1950s, Teledyne e2v has designed more than 450 thyratrons to meet the specific application requirements.

We work closely with our customers to provide switching solutions to the highest standards for high energy physics, medical, security, defence, industrial and radar applications. Through continuous product development and technical support of our customers, we offer solutions to meet exacting requirements.

National laboratories and platform manufacturers the world over trust us to understand their specific, highly complex challenges and provide them with the perfect solution.

The Technology


Teledyne e2v offers a diverse portfolio of switching devices that meet the requirements of the most demanding applications.

Our high-power pulsed thyratrons provide high voltage, high speed and high current switching capability with precise timing.

The product range includes glass, ceramic and metal envelope designs that switch voltages up to 100kV and currents up to 20kA.

We are especially proud of our partnerships with some of the most important laboratories in the world, working hand in hand with them to design and manufacture products that meet their complex specifications.

Applications and Products
Medical
Improving and saving lives

Every 0.25 seconds a patient is treated for cancer using Teledyne e2v technology.

Our thyratrons are found in over 90% of the world’s radiotherapy systems . They power the linear accelerators that produce the high-energy x-rays that destroy cancer cells.

We work with our clients to develop state-of-the-art devices, from design and research to manufacture and installation.

We also provide in-depth training and ongoing technical support to hospital engineers and medical professionals, enabling them to deliver faster and more accurate cancer treatment to patients every day.

Transport and security
Protecting our borders

Every day, Teledyne e2v thyratrons help protect people, infrastructure and borders from a wide range of threats and illegal activities.

They form the core of the linear accelerators used in gantry, mobile and portable cargo scanning systems around the world. The high-energy x-ray imaging enables authorities to safely and accurately detect weapons, stowaways, contraband and other prohibited items.

The technology is widely used at seaports, border crossings and other high-volume ports of entry – any location where reliable images, efficient processing and the ability to quickly interpret data is vital.

Industrial
Driving business efficiency and performance

Teledyne e2v thyratrons power an almost endless range of industrial applications.

From food processing, agricultural production and mining to rubber vulcanisation, polymer and plastic recycling and diamond seeding, the technology can be truly transformative.

Thyratrons power are also used in high energy x-ray imaging systems that are used in the non-destructive testing of civil infrastructure such as buildings and bridges, and potential hazards including high-capacity storage tanks, pressurised containers and pipelines.

The food processing industry also uses x-ray and electron technology to destroy bacteria, sterilise food and improve its quality and safety.

Defence
Protecting our forces and citizens

Teledyne e2v thyratrons power the military radars that are used to protect assets and detect hazards across land, air and sea.

They are specially designed to operate at extremely high frequencies and with very low noise levels to quickly detect small or complex threats at long range. They are also optimised for high pulse repetition frequency and quick start-up so that danger can be tracked from the start.

In an environment where it is crucial to be one step ahead, we are continually developing new technologies and systems to ensure our customers maintain their operational advantage.

High Energy Physics 
Trusted by national labs across the world

Scientists rely on precisely calibrated equipment to conduct their experiments, so the performance of the thyratrons within these platforms is crucial.

Our thyratrons are used in Crowbar applications, PFN modulators, beam injectors, beam extractors and boosters.
Many research teams will have very specific requirements. We work closely with engineers to provide the bespoke solutions and support they need. This often involves repurposing thyratrons as the research programmes evolve, and our experts have the breadth and depth of experience to ensure that this can be easily achieved.

We look forward to maintaining and growing our affiliation with critical science experiments around the world, offering the best possible product quality and technical support.
