Description

The 26th Workshop on Radiation Imaging Detectors, the IWORID 2025, will be opened.
The Swiss Light Source is nearing the completion of its upgrade to a fourth-generation synchrotron, significantly enhancing its brilliance. This leads to a higher photon flux, while improving the coherence of the beam across the entire energy spectrum, from extreme ultraviolet to 80 keV hard X-rays.
To support the increased photon rates, we are developing the MATTERHORN detector, a...
The ATLAS Inner Detector will be entirely replaced with a state-of-the-art all-silicon tracking detector (ITk) during the 2026โ2028 upgrade, designed to withstand the demanding conditions of the High Luminosity LHC (HL-LHC). The pixel detector, positioned at the core of ITk, will feature 3D sensor technology in the innermost layer (L0), where the expected particle fluence reaches up to 2 ร...
ITS3 - A truly cylindrical tracker for ALICE
Anna Villani on behalf of the ALICE Collaboration
The ALICE experiment at the CERN Large Hadron Collider (LHC) is optimized for the study of the strongly interacting state of matter arising in high-energy heavy-ion collisions through the tracking of particles at high multiplicities resulting from the collisions. The ALICE Inner Tracking...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, operating at the Large Hadron Collider (LHC) at CERN. TileCal is made of steel as absorber and plastic scintillators as active medium. The scintillators are read-out by wavelength shifting fibres coupled to photomultiplier tubes (PMTs). The analogue signals from the PMTs are...
The Timepix detector network inside the ATLAS cavern has proven to be effective in measuring luminosity and the radiation field composition during LHC Run-2 operation [1]. First tests of Timepix3 in this radiation environment provided promising results so that for Run-3, the network has been upgraded to a two-layer detector stack relying fully on the Timepix3 technology. Each two-layer...
Naturally occurring radionuclides such as potassium (K), uranium (U), and thorium (Th) are primary sources of ionizing radiation (ฮฑ, ฮฒ, and ฮณ) contributing to the radiation dose received by quartz and feldspar mineral grains used in luminescence dosimetry/dating. The heterogeneous distribution of radionuclides within or adjacent to individual mineral grains can lead to significant variations...
With the High-Luminosity Large Hadron Collider (HL-LHC) the number of events per bunch crossing increases. To cope with these high rates in the pixel trackers, per-pixel time measurements are required, which implies the need for fast sensors. The Inverted Low-Gain Avalanche Detector (iLGAD) is one of the options that is being investigated. This presentation will show the results of an inverse...
Hybrid semiconductor detectors with CdTe sensor chips find wide applications in medical and industrial X-ray radiography. These detectors enable direct radiation detection through their ability to effectively convert ionizing radiation into electrical signals. The design provides excellent detection sensitivity and eliminates analog noise. However, CdTe sensor chips are known to have crystal...
Timepix3 is an advanced hybrid pixel detector designed for precise particle tracking and energy measurement over a wide range of ionizing radiation [1]. Currently, Timepix3 detectors are equipped with a variety of semiconductor sensors, including silicon (Si), silicon carbide (4H-SiC), gallium arsenide (GaAs), and cadmium telluride (CdTe), each offering specific advantages depending on...
Electrons have emerged as an important complement to X-rays in crystallography, particularly for compounds that present challenges in growing crystals sufficiently large for synchrotron radiation (5โ10 ฮผm) or laboratory diffractometers (~50 ฮผm). Given the nature of electron-matter interactions, electron diffraction (ED) provides a way to experimentally determine the electrostatic potential of...
The High Energy X-ray Imaging TECHnology (HEXITEC) and the recently developed HEXITEC MHz technologies, developed by the UKโs Science and Technology Facilities Council (STFC), represent significant advancements in spectroscopic X-ray imaging applications. These ASICs are designed for high-resolution, energy-resolved detection of X-rays and gamma rays, and have been optimized for use with...
PERCIVAL, "pixellated energy-resolving CMOS imager versatile and large," is a 2-megapixel soft X-ray imager developed for use at FELs and modern-day synchrotrons by a collaboration of light sources (DESY, Elettra, Diamond, Pohang Accelerator Lab, and Soleil) together with Rutherford Appleton Laboratories. To meet the science needs at these facilities, a combination of capabilities is...
The advent of fourth-generation synchrotrons, such as the Diamond II upgrade, offers unprecedented flux increases of 10โ100ร, reaching up to $10^{12}$ photons/s/mmยฒ over a wide energy range (20โ100 keV). Fully leveraging these photon fluxes and high X-ray energies necessitates readout chips with exceptional frame rates and dynamic ranges, alongside the use of high-Z sensor materials. To...
Neutron imaging offers additional information compared to X-ray imaging because of the different types of interaction of the two different types of radiation. This technique is particularly valuable in fields such as nuclear engineering and non-destructive industrial diagnostics.
Based on 3D sensor technology, an innovative thermal neutron detection and imaging device has been developed...
SABRE is an international collaboration that will operate similar particle de-
tectors in the Northern (SABRE North) and Southern Hemispheres (SABRE
South). This innovative approach distinguishes possible dark matter signals
from seasonal backgrounds, a pioneering strategy only possible with a southern
hemisphere experiment. SABRE South is located at the Stawell Underground
Physics...
The Australian National University (ANU) has been conducting studies in directional detector technology, with the aim of building a large detector called CYGNUS. Eventually, such a detector is likely to be located in Australia's new underground physics laboratory at Stawell in regional Victoria.
The ANU group leads the experimental efforts of the Australian CYGNUS-Oz consortium through the...
Radiotherapy (RT) using X-rays is the main treatment strategy employed to treat human tumors with ~50% of all cancer patients receiving RT. The major drawback of RT treatment is that in order to deliver a lethal dose to cancerous cells, short- and long-term adverse side-effects are evident due to the irradiation of the surrounding normal healthy tissues that can severely impact the health and...
X-ray hyperspectral detectors using charge-integrating pixels detect individual photons at frame rates generally higher than one kilo frames per second (kfps). Owing to the slower analog processing, they enable spectroscopic analysis with sharper energy resolution, typically better than 1โฏkeV FWHM.
CITIUS is a recently introduced large-area, direct-detection X-ray detector, of which the...
