Nuclear researches

Atomic nuclei are groups of fermions, neutrons and protons, interacting through electroweak and strong forces. Likewise to what happens in atomic physics, nuclei are organized in shell structures, namely different properties such as binding energies, transition probabilities or the distances between quantum energy levels, assume peculiar values when the amount of protons or neutrons equal certain characteristic numbers. However, differently from atomic physics, the average field which keeps together nucleons is generated by the nucleons themselves, making the nucleus an extraordinary laboratory for the study of many body physics. Moreover, certain types of interactions exist, like the pairing one which couple together nucleons to certain spin configurations, governing quantum properties unique in nature. Another characteristic of nuclei is that mass numbers may vary from few units (like for instance for Helium or Lithium) to some hundreds of units (like for Uranium, last stable), with different values in the neutron or proton number. To this huge variety are associated different properties like lifetimes of ground and excited states, the kind of nuclear decay (gamma, beta, alfa, fission). Through suitable nuclear reactions one can synthesize and study properties of nuclei not available in nature, both from the point of view of nuclear structure and from the one of the reaction mechanism. The classes of experiments which are performed in nuclear physics are therefore extremely broad. One ranges from the study of ground state properties, like the mass, the electric and magnetic moments, to those of structure, like excited levels and the gamma transition probabilities, to the study of nuclear reactions with the partial or total reassembling of colliding nuclei, like transfer or fusion reactions, or the formation of nuclei through fission, break-up channels, or nucleus fragmentation. The Legnaro National Laboratory has a long tradition in nuclear physics research and is equipped with frontier accelerators and instrumentation able to compete with the best world centres in the field of heavy ions at energies close to the Coulomb barrier. LNL is one of the four national facilities funded by INFN with the mission of providing research infrastructures in nuclear physics and nuclear physics based applications for Italian and foreign users. The main research area is on nuclear structure and reaction dynamics, using heavy ion beams provided by the 15 MV Tandem coupled to the superconducting booster ALPI and the heavy ion injector PIAVE. Nuclear structure and reaction dynamics studies at bombarding energies close to the Coulomb barrier are based on dedicated instrumentation developed during the last years, i.e. large gamma arrays, magnetic spectrometers and particle detector arrays.

Innovation is the key to growth, competitiveness and thus social well-being in the 21st century. Providing new solutions to rapidly emerging societal problems is therefore crucial in an ever more knowledge-intensive economy. In this framework, the specific goals of technological research are to promote excellence science, to excite competitive industries and to establish a better society. INFN support applied physics and technological research through the 5th National Scientific Committe (CSN5): Legnaro labs in particular are a national and international reference for the development of the future prototypes and for the realization of the nowadays particle accelerators. They are employed in fundamental physics research, as well as in other research fields and in economic and social life. A strong interdisciplinary activity concerns developments in radiation detectors, electronics and information technology. These technologies have found broad applications in other science fields, as well as health, defense, cultural heritage and environment preservation. In biomedical field, technological research found relevant application in medical imaging, cancer therapy, dosimetry and treatment planning system in radiotherapy with proton and ion beam.

PLASMA4BEAM

National INFN Responsible: M. Cavenago
LNL person in charge: M. Cavenago

Plasma4beam (2017-2019) experiment is an integrated project to develop ion sources, ion coolers, computational techniques and measurement devices for high current ion beams and neutron detectors of interest for project ITER and other fusion reactors, and for SPES project. The experiment is based at five  INFN branches (BA, LNF, LNL, MI and MIB) and is performed in close synergy with ''Consorzio RFX'', Padua and the project PRIMA (Padua Research on ITER Megavolt Accelerator), which is developing the neutral injectors for ITER (nominal beam power 40 MW, that is 40 A of negative ion beam / 1 MV acceleration, for each injector).

Plasma4beam research activities are organized in five workpackages:

WP1: operation and development ( after our design and construction supervision) of a versatile test ion source NIO1, producing 9 beamlets of H- ions up to 15 mA each, 60 kV acceleration voltage; beam is continuously working, or has a duration comparable to ITER specification, as 3600 s). Financed with external funds.

WP2: Radiofrequency Cooler

WP3: development and construction of triple GEM neutron detectors (about which INFN has a long tradition also spread over other experiments and branches); in this case, detectors may have a fast temporal resolution and can give information on neutron energy and therefore on the production reaction.

WP4:  positive ion sources with high current (TRIPS and IFMIF-style)

WP5: theory of ion sources and of particle beams (H- ions with electrons) in strong space charge condition. In addition to using  existing codes, we wrote a code called BYPO introducing new techniques to defeat the granularity error of standard ray tracing(typical of previous codes). Moreover we discover and publish some more analytical (or semi analytical approximation) solution to problems of space charge, and of coupling between radiofrequency and ion source plasma, and of transport near the plasma/sheath/beam transition. In parallel to theoretical research, we built small plasma generators and extraction systems.

Introduction to particle physics

Legnaro National Laboratories (LNL) is also involved in research activities related to particle physics or sub nuclear physics at high energy. Such searches are not carried out at the existing LNL accelerator facilities, which are dedicated to low-energy nuclear physics, but in other international research centers, where large accelerators, reaching energy levels needed to explore in great details the sub nuclear components of matter, are installed.

The largest and most powerful accelerator ever is the Large Hadron Collider (LHC) at the European Organization for Nuclear Research - CERN in Geneva. LHC is installed near Geneva across the French-Swiss border.

CERN LHC

The main high energy physics goals that such a big accelerator facility has been pursuing are:

  • the study of the Higgs’ boson, discovered at LHC in 2012, (video) which could explain why particles have mass. The SM is a widely accepted theory tested with high precision in the last decades, which gives us a description of the elementary particles at the basis of the known matter in the Universe, as well as the way they interact each other;
  • a dramatic improvement of statistic uncertainty about the measurement of some interesting physics parameters, as well as the confirmation of some subnuclear processes which, although having rare occurrence, are however internal to the SM, involving in particular both top and bottom quarks;
  • Symmetry Violations studies and the observation of the state of matter known as "quark-gluon plasma";
  • the Standard Model and beyond, testing alternative physics theories such as those known as Supersymmetry (SUSY), Technicolor, Strings, Extra Dimensions, which might give an answer to some still unveiled issues discovered in the Universe in the last decade, such as the “Dark Matter” and the “Dark Energy”.

In short, the four, quite large, detector apparatuses available at LHC, probing the matter at the "infinitely small" level, aims at studying the "infinitely large", i.e. the Universe itself, from the birth up to present stage. To perform such a goal, the following four experiments and international cooperation (involving thousands among physicists, engineers, technicians and technologists) are studying the collisions products at LHC:

Legnaro labs are involved in the international efforts and collaboration on ALICE and CMS experiments mainly.

Astroparticle Physics

Fundamental physics research at the Legnaro Laboratories is also conducted without the use of accelerator machines. Two lines of research in precision physics at high sensitivity are active: the study of neutrinos and search for axions / properties of the vacuum. The final aim for these research fields is a deeper understanding of the connections between some fundamental concepts of quantum and relativistic physics such as mass and energy from the one side, and time and space to the other.

Neutrinoless double beta decay (CUORE and CUPID)

cuore The measurement of the neutrinoless double beta decay is the main task of the experiment CUORE. This measurement would allow us to get detailed information on the properties of the neutrino, one of the fundamental constituents of the Standard Model of particle physics. The apparatus of CUORE is based on a very sensitive temperature detector (bolometer), constituted by ultra pure crystals of tellurium dioxide (TeO2).

The Legnaro laboratories carried out the ultra-cleaning procedure of the copper used to hold the bolometric structure of TeO2, which is now placed in the Gran Sasso Laboratories of INFN. The ultra-cleaning procedure consisted in a sequence of 70 operations for each component, to be done for a total of 4000 pieces. Among the 70 operations of the cleaning protocol, 5 are of paramount importance: mechanical barreling, electrocleaning, chemical attack, passivation, and the final cleaning with vacuum plasma, according to the assumption that “nothing is cleaner than vacuum”. 

CUPID is the candidate successor of CUORE, with the introduction of the particle identification; it is under research and development.

 

 

Axion research (QUAX) and vacuum properties (PVLAS)


PVLAS








Vacuum is generally defined as a region of space without matter and radiation. In classical  physics the empty space has no properties or structures. However, this statement changes in modern physics: the vacuum is the state of minimum energy, and, following from Heisenberg’s uncertainty principle, it must be filled with fluctuations. The vacuum becomes populated with virtual particles: particles that appear and disappear within very short time intervals. Due to the presence of virtual particles, the vacuum has physical properties, which are studied in experiments with LNL staffs (PVLAS). In the PVLAS experiment the effect of a magnetic field on the vacuum is studied: the magnetic field acts on the virtual particles and the vacuum becomes similar to a crystal. A polarized laser beam traversing the magnetized vacuum will then change its polarization state: this can be detected by using a device based on an optical resonant cavity and an ultra high sensitivity polarizer. Such effects are so small that nobody has been able to measure them yet, and the cited experiments are trying to reveal them for the first time.

QUAX fotoThe search for cosmological axions using magnetized materials (QUAX) is a way to investigate dark matter. The axion can in fact interact with the electrons in a magnetic material immersed in a static magnetic field, and this result in the emission of electromagnetic radiation in the radio frequency range. By using a microwave cavity with very high quality factor and very sensitive radio frequency detectors it would then be possible to collect the emitted radiation and thus obtain information on the properties of the axion dark matter. To avoid the effect of the thermal background the experiment must be conducted at cryogenic temperature. The researcher forming the QUAX collaboration are studying the feasibility of this detection scheme.
