Welcome to Legnaro National Laboratories (LNL)

lnl flags LNL is one of the four national labs of the Italian Institute of Nuclear Physics (INFN). The mission is to perform basic research in nuclear physics and nuclear-astrophysics, together with applications of nuclear technologies.

Around 700 scientists from all over the world are involved in the ongoing research programs. Every day about 250 people work at LNL, half of them being INFN employees (physicists, engineers, technicians....) the remaining half coming from universities and research institutions in Italy and abroad. The laboratory budget is nearly 20 Million Euro per year, half for handling and research, half for personnel. Strength points are the development of particle accelerators and of nuclear radiation detectors, and the technology transfer.

The SPES exotic beam production system has been installed

After the installation of the Wien filter at the beginning of 2021, the positioning of the heart of the SPES project has been completed. The system houses the uranium carbide target which will produce the radionuclides by the cyclotron proton beam irradiation. The installation was particularly difficult, especially with regards to the positioning of the sensitive ceramic insulators, the cooling and the power systems of the chamber that will house the production target. Over 10 kW of electrical power will be needed for powering the entire system to a working voltage of 40 kV.
Now the system is in the final location; the installation and connection of the other line components are expected to be completed by the end of this year.

The second phase of the ISOL-SPES (Isotope Separation On-Line) system installation has started.

This phase involves the core of the SPES-ISOL project, the target reaction chamber.

The connections between the accelerator and the chamber are made possible by a complex system called “Front-End”.

Thanks to the Front-End, the target chamber receives more than 10 kW of electrical power, the cooling water, the high voltage up to 40 kV and the proton beam from the cyclotron to produce the exotic species used in the several research areas available in the SPES project.

The transport and installation of the Front End is a particularly tricky phase due to several brittle ceramic insulators that are present in this system.

Now that the Front End is in its final place, the other connections and installation works can proceed. More beam line components will be installed during this year.
