Recently, our NTG team attended IPAC’26, the 17th International Particle Accelerator Conference, held in Deauville, France.

IPAC is one of the key annual meeting points for the international accelerator community, bringing together researchers, engineers, institutions and industry partners to exchange knowledge on accelerator science, technology and future developments.

For us as a mechanical engineering company, the conference offered valuable insights into current projects and technological trends, as well as many fruitful discussions with experts, partners and potential customers.

We especially appreciated the personal exchange throughout the event. Conferences like IPAC are not only important for technical and business discussions, but also for maintaining relationships, building trust and creating new connections across the industry.

A big thank you to everyone we had the chance to meet in Deauville. We return with many positive impressions, new contacts and promising conversations to follow up on.

Optatec 2026 – we’re absolutely thrilled. We had some very productive meetings, and over the course of the year, you’ll find out what came of them. We now have a lot to sort out internally and are looking forward to what’s ahead—it’s going to be great.

This assembly demonstrates what a high-performance RF feedthrough / RF coupler window really requires:
The component must combine high-frequency capability, vacuum tightness, and mechanical stability — even under thermal and process-related stress.

The technical challenge starts with the material combination:

• Alumina ceramic (Al₂O₃) for electrical insulation
• OFHC copper for RF-compatible conductivity and high thermal performance
• Stainless steel for structural integrity and vacuum-compatible integration

The real complexity, however, lies in joining these materials.
Creating a reliable ceramic-copper-stainless steel assembly requires precise control of:

• material compatibility
• metallization
• joint gap design
• temperature profile
• process stability
• leak tightness and repeatability

A key feature of this project is the circumferential brazing joint.

While comparable applications have often relied on end-face brazing, NTG can now also reliably realize the far more demanding circumferential brazing process.
The advantage of circumferential brazing lies in the joint design across a continuous peripheral interface. This can provide important design and manufacturing benefits, especially in terms of load distribution, joint stability, vacuum tightness, and integration into complex assemblies.

In particular, brazing ceramic-to-metal joints is one of the most demanding disciplines in advanced joining technology. Different coefficients of thermal expansion and strict vacuum requirements leave no room for compromise.
This is exactly the kind of complexity we master at NTG.

We manufacture precision brazed assemblies for demanding technical applications — reliable, repeatable, and engineered for performance.

A tradition that brings us together 🐟

It has been a tradition for many years: on Aschermittwoch, herring is served in the NTG canteen.

On February 18, it was that time again—a small, simple tradition that means so much. We took a break from work for a moment, ate together, laughed, and enjoyed each other’s company.

Because in the end, it always turns out that
food brings people together. 🤝
