The development of detectors for high-energy photons, protons, and heavy particles has long been a key research topic, not only for fundamental studies but also for radiation monitoring in harsh environments – such as in hospitals during medical treatments and in outer space exploration. In this context, there is a rapidly growing interest in novels, high-performance, thin, and flexible...
Interventional radiology procedures are becoming increasingly common in modern clinical practice, often replacing invasive surgical interventions, despite increasing exposure of medical personnel to X-rays.
New epidemiological data correlating occupational exposure of interventional radiologists to radiation induced cataracts led ICRP to reduce the occupational dose limit for workers from 150...
The Jagiellonian Positron Emission Tomograph (J-PET) is the first modular and portable multi-photon PET scanner, which is a multidisciplinary detection system used in medical imaging as well as in fundamental research including discrete symmetry tests in positronium decays [1,2]. In addition to standard PET imaging, the J-PET scanner allows the positronium lifetime imaging in the human body...
Volumetric imaging of mm-sized soft tissue samples with micron resolution opens new possibilities both in clinical and research settings, driven by the growing need for studying micro and nanoscale structures in a three-dimensional context at the mesoscale.
In this talk I will report the first proof of concept for three-dimensional soft tissue imaging with a laboratory-based x-ray...
X-ray fluorescence (XRF) analysis is a non-destructive technique widely employed in the examination of cultural heritage artifacts. Its capacity to rapidly identify the elemental composition of materials without causing damage makes it an essential tool for analyzing paintings, frescos, manuscripts, pottery, metalwork, glass, and various other artifacts. The advent of portable XRF devices has...
Protein misfolding and aggregation are central to numerous neurodegenerative diseases [Selkoe, Nature, 2003]. In particular, amyloid-β (Aβ) and α-synuclein are key pathological proteins in Alzheimer's and Parkinson's diseases, respectively. Brain regions where these aggregates accumulate often exhibit high concentrations of metal ions, making it critically important to understand how metal...
Rowland circle-based and von Hamos spectrometers are the two most popular types of x-ray emission spectrometers. From the application point of view, there are two main categories of acquisition: (i) high energy resolution fluorescence detected x-ray absorption spectroscopy (HERFD XAS) at a constant emission energy and (ii) x-ray emission spectroscopy (XES) at a constant excitation energy, and...
"SHADOW" is a ray-tracing program originally developed by Franco Cerrina, widely adopted for the simulation of synchrotron radiation beamlines. Over more than four decades and across three generations of synchrotron sources, SHADOW has played a key role in the design and upgrade of numerous beamlines.
This work presents a comprehensive overhaul of SHADOW, resulting in the development of...
PANDORA (Plasmas for Astrophysics, Nuclear decay Observation and Radiation for Archaeometry) is a multidisciplinary project aimed at investigating β decays in stellar-like ECR plasmas, representing a breakthrough for fundamental studies on weak interactions in astrophysical contexts. The facility will rely on an extended diagnostic system. Among which, the X-rays diagnostic and spectroscopy...
We have developed, assembled and tested a novel device for Positron Emission Tomography (PET) capable of measuring polarization correlations of annihilation quanta. PET is know as an important medical imaging modality with applications in oncology, neurology and cardiology diagnostics. PET relies on detection of a pair of gamma rays created after positron annihilation in tissue. These...
This study investigates cerium migration in polymer electrolyte membrane fuel cells (PEMFCs) using a custom in-house X-ray fluorescence (XRF) spectroscopy system. Cerium serves as a crucial chemical stabilizer in fuel cells, scavenging destructive free radicals through Ce(III)/Ce(IV) redox reactions. However, prolonged operational conditions can induce complex cation migration across the...
X-rays are a standard tool for investigating the properties of metals, from determining their concentrations to probing their specific electronic states. At the National Laboratory of Frascati (LNF), the VOXES apparatus pursues this approach by implementing an X-ray fluorescence (XRF) spectrometer for extended sources. In this talk, I will present the capabilities of VOXES, highlighting its...
