The EAGLE array (European Array for Gamma Levels Evaluations) [1] is a multi-configuration detector set-up for in-beam nuclear spectroscopy studies at the Heavy Ion Laboratory (HIL) of the University of Warsaw. It can accommodate up to 30 Compton-suppressed HPGe detectors.
Building on this foundation, a new campaign, FLASH (Fast-Timing LaBr$_3$ Array for Spectroscopy at HIL), is planned...
iThemba LABS has pioneered a mobile gamma-ray detection unit[1] which allows a user to operate in the field and chart the location, strength \ and energy of gamma radiation. The system incorporates a sensitive \ scintillation detector[2] typically used for accelerator-based \ spectroscopy at the SSC laboratory and was integrated into a backpack \ incorporating a fast 125 MHz digitiser for...
Positron Emission Tomography (PET) is a powerful imaging technique that enables the study of physiological and molecular processes in vivo. The introduction of Time-of-Flight PET (TOF-PET) has driven significant improvement on image quality by enhancing signal-to-noise ratio and enabling potential dose reduction. This talk will explore the latest developments in detector technology, signal...
Accurate timing characterization of detected radiation events in Positron Emission Tomography (PET) provides Time-of-flight (TOF) information for detected coincidences, which improves the signal-to-noise ratio of the reconstructed images. In this work, we propose a method to train machine learning (ML) models to assign accurate timestamps to events measured in radiation detectors making use of...
This work investigates building a two-stage Compton camera in terms of energy resolution, efficiency, fast timing, and geometrical configuration for beam range monitoring in hadron therapy. While development of a clinical imaging device has made tremendous strides, there are challenges to be addressed.
A Compton camera prototype is investigated, assessing the optimal geometrical configuration...
Fast-Timing measurements in isotopes produced by transfer or fusion-evaporation reactions is challenging due to the appearance of several interfering $\gamma$-rays from different reaction channels. It is therefore necessary to clean up the reaction channel, or rather the $\gamma$-ray spectra, of the isotope of interest from contaminations. Usually the use of HPGe gates can be applied to clean...
For certain nuclei long-range octupole-octupole residual interactions can cause a reflection-asymmetric (pear) shape to occur. This octupole deformation, combined with quadrupole deformation, causes a separation between the centre of mass and centre of charge in the nucleus, resulting in a significant electric dipole (E1) moment. This effect enhances the strength of the E1 and electric...
Polonium isotopes having two protons above the shell closure at $Z = 82$ demonstrate a wide variety of high-spin isomeric states across the whole chain.
The structure of neutron-deficient isotopes up to $^{210}$Po ($N = 126$) is well established thanks to being easily produced through different methods, as opposed to their neutron-rich counterparts for which not much information is currently...

In some applications the transmission detectors are required to follow the path of radiation or to confirm that a particle entered a given volume. Moreover, such detectors should provide as much as possible information about the interacting radiation (energy deposited, time of interaction) and at the same time, change the particle state (direction, energy) as little as possible. We proposed a...
We study the temporal response of different arrays of Hamamatsu SiPMs coupled to fast scintillators. The detectors used include for instance a 36 Hamamatsu SiPM matrix (3x3mm), and a 4 Hamamatsu SiPM matrix (6x6mm), each with electronic readouts boards aiming to simplify the design. These arrays were coupled to fast scintillators, such as a LaBr3(Ce) truncated cone (1.5" high, with bases of 1"...
