Positron emission tomography (PET) is an important medical imaging modality, and although the technology is well established, there are still opportunities as well as a demand for better PET systems. The detection of annihilation photons in PET is based on scintillation light detection, but an inter ...

Rheumatoid arthritis causes changes in the optical properties of tissues in the joints, which could be detected using spectral imaging. This has the potential for development of low cost, non-contact method for early detection of the disease. In this work, hyperspectral imaging system was used to ob ...

The electromagnetic calorimeter, ECAL, is a sub-detector of the general-purpose \ flavor physics experiment, LHCb, operating at the LHC accelerator at the European Organization for Nuclear Research - CERN. Since one-third of heavy flavor decay products are $\pi_{0}$ mesons or other neutral particles ...

We present experimental results obtained with the LAPPD Gen-II large-size MCP-PMT. Using a custom-designed PCB capacitively coupled to the anode backplane with different segmentation patterns, the photo-detector is read out using the PETsys TOFPET2 and FastIC ASICs. The results reported in this pape ...

Single photon sensitive detectors used in high energy physics are, in some applica-tions, required to cover areas the size of several m2, and more specifically in very strong demand with an ever finer imaging and timing capability for Cherenkov Ring Imaging Detector (RICH) configurations. We are eva ...

For the particle identification systems of the future high-energy physics detectors, single-photon sensors with sub-mm granularity, high sensitivity, and mitigation strategy for operation in the neutron-irradiated areas are needed. Silicon photomultipliers are considered a baseline technology becaus ...

As a part of the LHCb RICH Future upgrades experimental program, we studied hydrophobic aerogel tiles from Chiba University during the 2021 CERN SPS testbeam. In a 180 GeV/c proton beam, we tested aerogels with different refractive indices and different thicknesses. The Cherenkov light radiated from ...

Cherenkov TOF PET Scanner;
The detection of annihilation photons in positron emission tomography (PET) is based on scintillation light detection, but an interesting alternative is detection based on Cherenkov photons. Dense Cherenkov radiators provide an opportunity for high gamma detection efficiency—due to their high stoppi ...
