NTG has manufactured and delivered two normal-conducting 108 MHz IH cavities designed for continuous-wave operation to the GSI Helmholtz Centre for Heavy Ion Research.

Precision-machined drift tubes, sophisticated water-cooled structures and demanding geometric, vacuum and RF requirements: this project showcases NTG’s manufacturing expertise in accelerator technology.

A big thank-you to the entire GSI team for the trust, constructive dialogue and excellent partnership!

High-performance technologies require one essential foundation: a perfectly controlled vacuum environment.

At NTG, vacuum technology has been one of our core competencies for decades. We design and manufacture customized vacuum solutions for demanding applications in research, science, and high-tech industries – where precision, reliability, and cleanliness are critical.

Our expertise includes:
✔ Custom vacuum chambers for high and ultra-high vacuum (UHV) applications
✔ Motion systems for vacuum environments
✔ Aluminium vacuum chambers with our in-house developed bi-metal CF flanges
✔ Precision manufacturing and assembly for highly specialized customer requirements

From individual components to complete vacuum systems, every solution is engineered to meet the unique demands of our customers. Our in-house expertise in design, manufacturing, assembly, and testing ensures maximum quality and performance throughout the entire project.

When precision begins with the environment, vacuum technology makes the difference.

Particle accelerators are at the heart of groundbreaking discoveries in science, medicine, and industry. Their performance depends on one critical factor: precision.

At NTG, we combine decades of experience in the design, engineering, manufacturing, and assembly of high-performance accelerator components and systems.

Our expertise covers the entire development process—from beam dynamics and RF design to thermal analysis, precision manufacturing, assembly, alignment, and RF tuning.

Our capabilities include:
✔ RFQ particle accelerators
✔ IH resonators and CH structures
✔ Beam diagnostics
✔ Ceramic-to-metal assemblies
✔ High-precision vacuum components
✔ Custom-engineered solutions for research facilities and industrial applications

Every project is unique. That’s why we work closely with our customers to develop tailor-made solutions that meet the highest technical requirements—supporting research institutions and industry worldwide in advancing accelerator technology.

Strengthening Manufacturing Capabilities with the SICMI PMM 200 ME

We are pleased to announce that NTG has expanded its production capabilities with the addition of the SICMI PMM 200 ME hydraulic gantry straightening press.

Designed for straightening sheet metal, profiles, welded assemblies, and heavy metal components, the PMM 200 ME offers exceptional flexibility. Thanks to its gantry design, the press moves over the workpiece, making it ideal for processing large and heavy components with outstanding precision.

Key specifications:
🔹 Pressing force: 200 tons
🔹 Cylinder stroke: 500 mm
🔹 Table dimensions: 3,000 × 2,550 mm
🔹 Clear distance between uprights: 2,550 mm
🔹 Total weight: approx. 8,500 kg

By investing in the SICMI PMM 200 ME, NTG continues to strengthen its manufacturing capabilities, ensuring the highest levels of precision, quality, and efficiency for demanding industrial applications.

With the manufacturer qualification according to DIN 18800-7, Class E, the so-called “Großer Eignungsnachweis” (major suitability qualification), it was confirmed at an early stage that we are qualified to manufacture demanding and safety-relevant steel structures.

The qualification level at the time included, among others:

• ✔ Dynamically loaded structures, such as crane runways and cranes
• ✔ Temporary structures, such as festival tents and amusement rides
• ✔ Working and protective scaffolding
• ✔ Structures made of high-strength and fine-grained structural steels

Although DIN 18800-7 has since been replaced by DIN EN 1090, this qualification remains an important testament to our extensive experience and expertise in structural steel construction.

The requirements of the former Class E correspond in many areas to today’s high execution classes EXC 3 and EXC 4.

Naturally, we also hold the relevant certifications according to DIN EN 1090 today.

For us, this certificate is far more than just a document. It represents quality, expertise, and responsibility – particularly when manufacturing demanding and safety-relevant steel structures.
