Introduction

The Gamma Spectroscopy group performs nuclear structure studies using stable beams provided by the TANDEM-ALPI-PIAVE (TAP) accelerators of Legnaro National Laboratory, and high-resolution Ge arrays coupled to different ancillary detectors. The group works in close collaboration with the “Galileo Galilei” physics department of the University of Padova and INFN-Padova. Furthermore, the group belongs to the GAMMA collaboration for nuclear physics. This collaboration is part of the INFN – National Scientific Committee 3 (CSN3) initiative, which involves 5 INFN divisions:

The group is also involved with SPES, which is a next generation ISOL-type accelerator that together with the operation of existing machines, is the future of LNL. SPES will provide Radioactive Ion Beam for nuclear physics and astrophysics research, as well as for interdisciplinary applications.

Currently, the AGATA array is being employed to detect γ radiation emitted after reactions such as fusion-evaporation, and low-energy Coulomb excitation. At the moment, GALILEO, the native array for detection γ-ray radiation, is not operational as all efforts are focused on AGATA.

The physics program of the group is focused, but not limited, on following topics:

Shell structure in n-rich nuclei
Isospin symmetries and n-p pairing
Pigmy resonance of interest in astrophysics
Structure of nuclei at the proton-drip line
Critical points and phase transitions between different nuclear shapes

In addition to the local activities, the group also performs research in collaboration with different laboratories such as GANIL, ISOLDE, JYU, the RIKEN Nishina Center, and GSI FAIR

AGATA@LNL

AGATA (Advanced GAmma Tracking Array) is a highly segmented High Purity Germanium (HPGe) detector array. It is a European collaboration project funded by twelve countries in Europe. The project was proposed in 2001 and in 2002 it was signed by the participant countries. AGATA is capable of high counting event rates and can be coupled with ancillary detectors, such as magnetic spectrometers, fast-timing detectors charged particles or neutron detectors. The AGATA detectors are Ge-detectors that are 36-fold segment with six-fold azimuthal and six-fold longitudinal segmentation.

Since 2022, AGATA array is installed in the Legnaro Laboratories, where it is coupled to the magnetic spectrometer PRISMA. AGATA array is complemented by 9 LaBr₃ detectors. Detailed description of AGATA setup at LNL, data acquisition system and complementary instrumentation is given in NIM A paper.

Performance figures of AGATA obtained during the 2022 campaign were published in Legnaro Annual Reports here and here. Note that the additional shielding was present in front of AGATA during this evaluation, details are given in the reports.

GALILEO

GALILEO (Gamma Array of Legnaro INFN Laboratories for nuclEar spectrOscopy) is the current high-resolution Ge array for advanced in-beam γ-ray spectroscopy studies constructed and installed at LNL.

The first phase of GALILEO was operational between 2015 and 2019 and consisted of 25 GASP tapered detectors coupled to Neutron Wall as shown in the picture. In a second stage of this phase, 10 GASP detectors were moved to the forward angles (replacing Neutron Wall) and LaBr₃ detectors were mounted at 90° to optimize the setup for measurements using the Plunger.

In its second phase, GALILEO will consist of 25 GASP tapered detectors at 90° and forward angles, and 10 triple clusters built using capsules of EUROBALL, mounted at backward angles. At the moment 20 GASP detectors and one triple cluster are mounted in the structure.

The HPGe detectors are surrounded by anti-Compton shields in order to reach, for the whole array, a peak-to-total ratio of about 55%. A 5cm thick heavy-metal shield improves Compton rejection, avoiding direct γ -ray interactions in the BGO shields. The geometry of the array is designed to maximize the photo-peak efficiency under typical in-beam medium-high γ-ray multiplicity conditions, achieving a value of 6.4%. GALILEO can be coupled to different ancillary devices.

Check out the list of GALILEO physics publications, or take a look at some of the technical publications. You can also see previous thesis regarding GALILEO or its ancillary devices.

Previous Arrays

The group has a well-established expertise in nuclear spectroscopy with high-resolution gamma-arrays. Since the first experiments performed in the 90s, the group has hosted GASP, EUROBALL, CLARA, as well as the first stage of the last-generation European gamma-array, the AGATA demonstrator.

PRISMA

Nucl. Phys. A

PRISMA is a large-acceptance magnetic spectrometer for heavy ions. Its design is based on a simple quadrupole-dipole configuration, with no hardware elements correcting for the optical aberrations, which are corrected instead via a software reconstruction of the trajectories of the nuclei inside the spectrometer. The trajectories are deduced from the point of entrance in the spectrometer and in the focal plane, where position-sensitive detectors are placed. The start detector of PRISMA is based on an MCP, while the focal plane detector is based on a MWPPAC. These detectors provide also a time-of-flight measurement. An ionisation chamber placed after the MWPPAC measures the charge and total energy of the incoming ions.

PLUNGER

NIM A

EUCLIDES

Eur. Phys. J. A

The EUCLIDES array is based on dE-E telescopes, the silicon thickness is 130 μm and 1000 μm for dE and E layers respectively. This allows the discrimination between light charged particles. 40 telescopes form a self-supported structure with the solid angle coverage close to 80% of 4π sr. Detector is made out of pentagonal and hexagonal detectors, the surface of each telescope is approximately 10cm².

These values can be however adjusted by changing the distance of the array from the target.

SAURON

Micron Semiconductor Ltd

SAURON is an annular double-sided silicon stripped ion detector for detection of light charged particles. Junction side is divided into 4 quadrants, each with 16 radial strips; ohmic side is divided into 16 azimuthal strips. Placing detector at standard 5cm distance from the target provides angular coverage of 25-44° if mounted forward, or 136-154° if mounted backward. The distance from the target may be adjusted. Available are 300, 500, 1000 and 1500 μm thick detectors.

CTADIR

The goal of the Cryogenic Targets for DIrect Reactions (CTADIR) research project is the construction of cryogenic targets for the study of direct nuclear reactions with the exotic beams produced by the upcoming SPES facility at LNL. The CTADIR project has three research units: INFN-LNL, University of Padova and University of Milan. The INFN-LNL, in particular, is in charge of developing a cryogenic target for ^3,4He, designed to be coupled to compact-geometry state-of-the-art detector arrays such as AGATA or GRIT. The cryogenic target has to be kept at temperatures below 10K in order to achieve the desired target density within a limited space of several millimetres.

The project is financed by the PRIN 2017 call for funding.

Open projects

The group offers different thesis projects for bachelor, master and PhD thesis.
Below you can find some of the possible topics for your thesis. Contact the corresponding supervisor if you are interested!

Master Thesis: A new tool for the search for electric dipole moments: study of octupole structures in the light U, Th and Pa isotopes via Multinucleon Transfer

Supervisor: Kseniia Rezynkina, Francesco Recchia

The student will be involved in the experiment aiming to study octupole collectivity in U, Th and Pa isotopes. We plan to do this in the LNL laboratory via a Multi-Nucleon Transfer reaction from a 232Th target, using the highly segmented gamma-ray tracking array AGATA and the electromagnetic spectrometer. These nuclei are good candidates for the studies of the Electric Dipole Moment (EDM) in the atomic nucleus, since they are predicted to have pear-shaped ground states. However, data for Th, Pa and U nuclei are incomplete and the theories give quite divergent predictions for some of the measurable observables. Main aim of this measurement is the determination of the low-lying structure of 226,228U (N=136) allowing, through the difference of the aligned angular momentum, a characterization of the octupole structure. The student will participate in the preparation of the experiment to be performed at Legnaro, in the data taking, and will take care of the first phase of the data analysis.

Master Thesis: Medical applications: Towards a new medical imaging modality, gamma-MRI, using long-lived polarised unstable tracers

Supervisor: Magda Kowalska (CERN), Francesco Recchia

This project is devoted to a new medical imaging modality that will use long-lived polarised Xe isomers inside a tailor-made low-field MRI magnet. Thanks to signal detection via changes in gamma-decay asymmetry, the approach can reach a billion times higher sensitivity than regular NMR and MRI. At CERN, we work on intense and pure Xe isomers samples to be sent to our colleagues in Geneva. The student will participate in preparing stable Xe samples for irradiation at reactors and for direct production of Xe isomers as a beam at the ISOLDE facility. He/she will help with setting up small experimental setups meant for extracting the samples from quartz vials or metallic foils and enclosing it in metallic transport containers. The student will also set up gamma detectors used to determine the Xe activity received from a nuclear reactor or produced at ISOLDE 1.

Master Thesis: Experimental study of the Nuclear Structure in the Island of Inversion

Supervisor: Pablo Aguilera, Francesco Recchia

The evolution of the shell structure around the island of inversion IoI is still a subject of debate. The particle-hole excitation plays a fundamental role in our understanding of the nuclear structure around the Island of Inversion (IoI). In the medium mass region at N=20 the 32Mg becomes the centre of the island of inversion, where the 0+ ground state exhibits an intruder configuration of 4p-4h excitations, and an excited 0+ state corresponding to the normal configuration predicted by the single particle shell model. This collective behaviour is the result of quadrupole correlations, favouring the intruder f7/2 and p3/2 orbitals. In order to understand the mechanisms that produce this phenomenon, it’s necessary to study the evolution of the collective behaviour in the neighbouring nuclei. The aim of this thesis will be to study the region around the IoI at N=20 via multi-nucleon transfer reaction and lifetime measurements in order to track intruder configurations in neighbouring nuclei.

A multi-nucleon transfer reaction will be performed in the Legnaro National Laboratory (LNL) using a 238U target and a 26Mg beam provided by the Piave-Alpi accelerator. The target will be surrounded by The Advanced GAmma Tracking Array (AGATA) coupled to the PRISMA magnetic separator. This configuration allows one to identify each fragment and perform lifetime measurements in the femto-second range with the Doppler Shift Attenuation Method (DSAM). The candidate will be able to participate in the experiment at the LNL and will analyse the data for the selected channels in collaboration with other research groups.
