Welcome to Legnaro National Laboratories (LNL)

lnl flagsLNL 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.

A new type of resonant cavity suitable for operation in high magnetic fields

In the framework of the Quaerere Axion (QUAX) experiment, the INFN researchers from LNL and Padova have achieved an important goal in the haloscope resonant cavities characterization. For the first time ever, a dielectric resonant microwave cavity in an high magnetic field (6 Tesla) has reached a quality factor Q of 107. This important result was obtained at LNL during the experimental run from 22nd to 26th of March 2021 and leads to an improvement in the quality factor of the currently available cavities by more than one order of magnitude. The high performance reached, is of paramount importance in the search for axions, candidate particles as dark matter constituents, by means of haloscope experiments. The novel result could open up new scenarios in the quantum sensor field and in the design of new types of accelerating cavities.
