The VELO detector is one of the core elements of the LHCb spectrometer. Its1
upcoming upgrade will consist of a new type of Velopix sensor. It branches from a2
Medipix family of silicon pixel matrix sensors. One of its operational challenges3
with future data taking at the Large Hadron Collider will be the ability to detect4
faulty (masked) pixels and monitor them. In this work, we propose...
Advanced devices for diagnostics and medical therapy require a constant and stable power source. The disadvantage of commonly used uninterruptible power supply (UPS) is the heavy weight[1], centralization and the need to use specially prepared rooms and dedicated electrical installations. The aim of the presented research is to prepare a safe, economic and modular Uninterruptible Power Booster...
The existence of CP violation in charm particle decays has been elusive for a long time for experimentalists and has been observed for the first time in 2019 in the LHCb experiment. During the LHC Run 1 and Run 2, the LHCb collaboration collected huge data samples on a scale never seen before. These data enable the most sensitive searches for CP violation ever performed. These measurements are...
Modular J-PET is the latest prototype of the Jagiellonian-PET, based on long plastic scintillator strips [2]. The modularity of this prototype allows for cost-effective imaging of multi-photon annihilation and positronium imaging, straightforward assembly, and portability [1-3]. Moreover, due to the low weight of a scanner, it is possible to perform an examination with a static bed and mobile...
Gamma-MRI is a future imaging modality that should allow the simultaneous exploitation of the sensitivity of gamma-ray detection (SPECT) and the spatial resolution and flexibility of MRI [1]. The approach uses, like in SPECT, gamma-emitting nuclei, which are highly polarized and thus exhibit anisotropic gamma-ray emission, whereas their spins are rotated by rf pulses, like in MRI. The signal...

The unique features that PET scanners have provided to the specialists in diagnosing diseases and investigating the physiology of the body have facilitated the development of a more advanced generation of tomographs in order to improve their performance, called Total-Body PET scans.
Due to the larger AFOV, TB PET scanners provide more...
Radiotherapy aims to deliver a specific dose of radiation to the treated area, destroying the tumour. Thanks to the use of newer technologies and their continuous development, it is possible to very precisely deliver the planned doses of radiation to the treated areas, while reducing the exposure of healthy tissues to radiation. Undoubtedly, physical simulations and the use of algorithms...
