Drift Tube Linac: the future global neutron source in Lund
 In the heart of the Swedish city of Lund, the future of nuclear research is being created: the Drift Tube Linac (DTL) European Spallation Source (ESS). Europe is on the threshold of a new era in nuclear research thanks to the work of INFN researchers. This linear accelerator is made possible thanks to the international collaboration and technological leadership of the Italy's National Institute of Nuclear Physics (INFN).



What is the Drift Tube Linac (DTL)?

The installation of the Drift Tube Linac (DTL), the pinnacle of innovation in nuclear research, has begun. It will be a milestone in modern science when completed at the European Spallation Source (ESS) in Lund. This extraordinary linear accelerator is the result of an unprecedented effort by researchers from the Legnaro National Laboratories (LNL) and the Turin Section of the National Institute for Nuclear Physics (INFN). The DTL consists of five cavities, each of which plays a crucial role in the proton acceleration process. These cavities, extraordinary engineering creations, extend over a total length of 40 meters. Inside these cavities, protons are accelerated from 3.6 to 90 MeV, reaching speeds approaching the speed of light.


This incredible acceleration is the result of years of research, design and experimentation by INFN scientists. These experts coordinated all stages of the process, from initial assembly to final testing, ensuring that each component of the DTL worked in perfect harmony. The technological challenges faced during this process were immense, but thanks to the determination and experience of the INFN teams, every challenge was overcome.



The Neutron Source Research Project

The contribution of the National Institute of Nuclear Physics (INFN) to the realization of the Drift Tube Linac (DTL) was fundamental for the neutron source. In fact, the INFN played a crucial role in several aspects of the project, demonstrating its leadership in the field of advanced nuclear research. One of the most complex aspects of the DTL project was the fabrication of the superconducting cavities. This process is extremely sophisticated and requires very high precision and technological expertise. Italy's INFN has excelled in this phase, demonstrating that it has the expertise to tackle technological challenges at the highest level. The production of superconducting cavities requires not only advanced engineering knowledge. It also requires a deep understanding of the principles of particle physics.


Researchers at Legnaro National Laboratories (LNL) and the Turin section of INFN faced complex challenges to achieve this goal. Using high-tech components, they created a system that is not only incredibly efficient, but also extremely reliable. The precision of fabrication and assembly, critical to the proper functioning of the DTL, was achieved through a combination of unparalleled technical expertise and attention to detail.



The Importance of Accelerated Particles

The Drift Tube Linac (DTL) represents a milestone in scientific research with its extraordinary ability to accelerate protons to extreme speeds. This project opens up a world of possibilities in a wide range of fields. In a wide range of scientific fields, accelerating particles to such high speeds contributes to groundbreaking discoveries and practical applications. By studying particles accelerated to speeds close to the speed of light, scientists can analyze the atomic world in greater detail. This allows them to explore the atomic structure of materials with unprecedented resolution, revealing fundamental secrets about the composition and behavior of materials.


This paves the way for applications in areas such as advanced electronics, materials engineering, and sustainable manufacturing with new materials that are stronger, lighter, and more responsive. A deeper understanding of particles can also be applied to energy. Scientists will be able to study high-energy nuclear reactions, paving the way for controlled nuclear fusion - a potentially limitless and clean source of energy. Particle acceleration research will also contribute to the development of more efficient accelerator technologies, which may be used in particle accelerators for industrial and medical purposes.
