The European XFEL is a state-of-the-art facility that produces brilliant X-ray flashes with unprecedented brilliance and pulse duration. It delivers up to 27,000 pulses per second in 10 trains per second, with each train containing up to 2700 pulses at a rate of up to 4.5 MHz. This has opened up new opportunities for scientific research in fields such as materials science, structural biology,...
Detection of soft X-ray photons with high spatial and temporal resolution often involves a process of electron multiplication as the charge produced by a single photon is not sufficient for an accurate event encoding. Microchannel plate (MCP) electron multipliers have been widely used in photon counting detectors where a photoelectron produced by the incoming X-ray photon is converted into a...
ALICE is one of the four major experiments at CERN Large Hadron Collider (LHC), studying the physics of strongly interacting matter at the highest energy densities reached so far in the laboratory. For this purpose, the ALICE detector is optimised to study the collisions of nuclei at the ultra-relativistic energies provided by the LHC. The optimisation involves efficient and precise tracking...
The Belle II experiment at KEK in Japan is upgrading its vertex detector system to address the challenges posed by high background levels caused by the inceased luminosity of the SuperKEKB collider. A proposed vertex detector upgrade aims to install an all-layer monolithic pixel vertex detector based on fully depleted CMOS sensors in 2027. The new system will use the OBELIX MAPS chips to...
We will present an overview the development of a series of detectors in the SparkPix family, designed to match the increased repetition rate of LCLS-II. Each detector is customized to meet the specific requirements of different experiments, and dedicated information extraction engines are integrated into each SparkPix ASIC to enable frame rates up to 1 MHz. The article discusses the overall...
This work presents experimental performance results of a first set of p-type Si and CdTe SPHIRD (Small Pixel High Rate photon counting Detector) prototypes [1]. The SPHIRD project targets a new generation of photon counting hybrid pixel detectors for synchrotron radiation applications with small pixels and operating between 10 and 30 keV. The current prototypes are based on an MPW test readout...
Compared with conventional X-ray radiation therapy, carbon-ion beam radiotherapy reduces the dose to the healthy tissue around a tumor thanks to the escalating dose at the Bragg peak. We developed a tracking system for secondary radiation from carbon-ion beams based on seven modules of four Timepix3 detectors (โquad moduleโ). The tracking system measures the secondary radiation of different...
Some medical and industrial X-ray imaging applications need to reconstruct an image on a flexible surface, so they use photographic film rather than electronic detectors. Current flat-panel X-ray imaging detectors are difficult to adapt to these applications. We will present the FleX-RAY project, which aims to create an electronic X-ray detector with the flexibility of photographic film,...
Soft X-rays (in the range of 200-2000 eV) are of great interest for imaging applications for a large variety of sectors. These include: imaging of organic samples, e.g., in the โwater windowโ (between C and O, K-edges: 277 eV to 525 eV), anomalous scattering experiments around many K-edges of light elements, and L-edges of 3d transition metals (relevant to magnetic and superconducting...
Text BoxFLASH radiotherapy (RT) is attracting a significant interest since the first investigations carried out in 2014 [1]. Several preclinical studies worldwide have demonstrated that ultra-high dose rate (UHDR) beams produce an improvement of normal tissue sparing, compared to conventional dose-rate RT, while maintaining same tumor control probability (FLASH effect). However, to fully...
Research at the frontier of particle physics often requires the search for phenomena of extremely low probability of occurrence, known as "rare events". One such search is for the hypothetical particles that may compose the mysterious dark matter (DM) of the Universe, such as Weakly Interacting Massive Particles (WIMPs) or axions. These low-energy events with faint probability of occurrence...
This work provides an update on the XIDER project, a study aimed at developing a 2D X-ray charge integrating hybrid pixel detector designed to operate with high-Z semiconductor sensors by implementing the incremental digital integration readout. The XIDER front-end chips are designed in 65 nm CMOS technology with a pixel pitch of 100 ยตm. Each pixel includes a charge integrator and a digitiser...
The progress in high-energy astrophysics is driven by two engines: deepening and development of the science objectives, and the progress in the measurement techniques, supported by the available detectors. The detectors in astrophysical instruments carry out 3 basic kinds of measurements: timing, spectral, and position. However, in most cases, these must all be accomplished within one...
Today, cancer treatment with ion beam is well established and studied. This method allows to deposit the maximum dose to the tumor and minimize the damage of healthy tissue, due to the Bragg peak of the ion energy deposition near the end of the particle range. During the treatment it is possible to provide volumetric dose delivery by changing the particle energy (penetration depth) and...
The International Agency for Research on Cancer estimated a 25% risk of tumor incidence in the European population (2018), destined to increase in the coming years. Prevention and early diagnosis remain the fundamental tools, and nuclear imaging plays a pivotal role for noninvasive diagnosis.
One of the most used diagnostic technology is the Single Photon Emission Computed Tomography...
In nuclear and high-energy physics research and in radiation related applications the measurement of the deposited energy and direction of charged particles may be needed with high discrimination against background and unwanted radiation. This task can be challenging in particular in mixed-radiation fields containing light charged particles (e.g., electrons, muons) and heavy charged particles...
A detection technology for thermal neutrons combining hybrid double gap timing resistive plates chambers lined with a 10B enriched solid neutron converter (10B-RPCs) is being developed at LIP-Coimbra [1]. Our previous studies performed on neutron beamlines at ILL (Institut Laue-Langevin) and FRMII (Research Neutron Source Heinz Maier-Leibnitz) have already demonstrated the feasibility of...
