I will discuss fast optical cameras based on the back-illuminated silicon sensor and Timepix3 data driven readout. The intensified version of the camera is single photon sensitive and since recently has been used for a variety of quantum imaging and other applications. I will talk about recent results and new ideas, focusing on topics of quantum-assisted astronomical interferometers. I will...

The development of direct pixelated detectors has played a key role in the resolution revolution in which structures of macromolecular complexes are obtained at near-atomic resolution by cryo-EM [1]. Monolithic active pixel sensor (MAPS) detectors are currently widely applied for cryo-EM, however, they have their best performance at 300 keV and have relatively low readout speed. The Timepix3,...

The possibility to implement the beneficial outcomes of FLASH effect in clinical practice lately has been object of extensive research activity. From the experimental point of view a significant challenge is related to the monitoring at FLASH intensities of therapeutic beams, since conventional monitors are affected by saturation effects and discharges due to the extremely high instantaneous...

To overcome particle therapy limitations, several treatment verification techniques based on the detection of secondaries have been developed, but a clinical device to be included in the patient routine is yet to be available. Recently, we developed a reconstruction model to estimate the time-depth distribution of the prompt photon emission with a multiple Prompt-Gamma Timing (PGT) detector...

Cancer treatments have been performed with X-rays and ions (e.g., protons and carbon ions) over the years. The high dose conformity that allows better sparing of healthy tissue is a demonstrated advantage of carbon ions over x-rays [1]. This dose conformity can be impacted by to anatomical changes between treatment fractions, which can lead to an increase of the dose to healthy tissue and to a...

Spectral and phase-contrast imaging techniques have been widely exploited at synchrotron radiation facilities. Their implementation requires in many cases the use of crystals either to prepare or to analyze the X-ray beam. For instance, energy dispersive spectral systems make use of multiple or bent crystal monochromators to spatially resolve different energy components at the detector...

A new generation of a modular high-resolution spectral imaging camera has been developed from synchronized array of pixel detectors Medipix3 within the European Union Horizon 2020 project X-mine. The aim of the project was to increase the potential of European mineral resources without generating adverse environmental impact by supporting more efficient ore extraction in existing mining...

New generation of synchrotron and plasma accelerators will produce coherent radiation with extremely high brightness. Photon beams from these machines will greatly extend the present research capabilities and will reveal new opportunities in imaging, spectroscopy, structural and dynamic studies, and other applications. Development of beam diagnostic instrumentation with high precision becomes...

Localization of radioactive sources is a major concern in the nuclear industry whether in decommissioning phases of nuclear facilities, nuclear waste management applications, radiation protection or Homeland Security. Therefore, gamma imaging emerges as a measurement solution that allows localizing and identifying radioactive sources in near and far field, which reduces the dose received by...

Established methods for high-resolution X-ray structure determination are based on far-field coherent diffractive imaging (CDI). However, in the interaction of light with matter incoherent processes occur, that are sometimes predominant over the coherent ones. They are considered detrimental in the CDI approach. The approach called incoherent diffractive imaging (IDI) opens up fundamentally...

Photon counting detectors can enable increased spatial resolution and improved contrast and/or lower radiation dose. In particular, lower concentrations of iodine can potentially be detected and quantified, which is important in angiography or perfusion imaging. Moreover, beam hardening artefacts will disappear with material base decomposition in the projection domain. Electronic noise can be...

A novel irradiation platform for pre-clinical proton therapy studies foresees proton imaging for positioning and accurate treatment planning [1]. While proton imaging at synchrocyclotron-based proton therapy centers is challenging in single particle tracking mode due to high instantaneous particle fluxes, it is feasible in integration mode. Large-area CMOS sensors allow the determination of a...

Background and purpose: In-beam Positron Emission Tomography (PET) is one of the modalities that can be used for in-vivo non-invasive treatment monitoring in proton therapy. The INSIDE system, installed at the National Center of Oncological Hadron therapy (CNAO), has acquired in-beam PET data during several patient proton therapy treatments. Despite the fact that PET treatment monitoring...

Proton and ion beams are commonly used worldwide for radiation therapy, offering advantageous dose distribution and increased relative biological effectiveness (RBE) compared to photons. While the RBE is assumed to vary with linear energy transfer (LET) of particles, currently only the constant RBE is taken into account in treatment planning due to a lack of tools for its experimental...

To study the 'proton Computed Tomography' (pCT) technique the INFN-Prima collaboration has built and successfully tested a 20x5cm2 field of view system based on a silicon microstrip tracker and a YAG:Ce scintillating calorimeter. This apparatus has demonstrated the feasibility of the pCT for objects with size suitable for pre-clinical studies [1]. Recently a possible clinical application of...

The Large Hadron Collider (LHC) at CERN will be upgraded to the High-Luminosity LHC (HL-LHC) until 2029. In order to fully exploit the physics potential of the high luminosity era the experiments must undergo major upgrades. In the context of the upgrade of the Compact Muon Solenoid (CMS) Experiment the silicon tracker will be fully replaced. The outer part of the new tracker (Outer Tracker)...
