Characterization of a flexible a-Si:H detector for in vivo dosimetry in therapeutic x-ray beams
Sylvain Dunand, Jonathan Emanuel Thomet, Luca Massimiliano Antognini, Matthew James Large
BackgroundThe increasing use of complex and high dose-rate treatments in radiation therapy necessitates advanced detectors to provide accurate dosimetry. Rather than relying on pre-treatment quality assurance (QA) measurements alone, many countries are now ...
Hoboken2024Innovative dud detection based on JET DT experience
Olivier Sauter, Alessandro Pau
DT operations at JET gave a unique and invaluable opportunity to design, develop and test real -time controllers that will be applied in future burning plasma devices, as ITER and SPARC. Among them, the dud detector [L. Piron et al. 2019 Fusion Eng. Design ...
Lausanne2024A thermotropic liquid crystal enables efficient and stable perovskite solar modules
Mohammad Khaja Nazeeruddin, Yong Ding, Bin Ding, Cheng Liu, Jian Xu
Perovskite solar cells have seen impressive progress in performance and stability, yet maintaining efficiency while scaling area remains a challenge. Here we find that additives commonly used to passivate large-area perovskite films often co-precipitate du ...
Berlin2024Radiation-tolerant Multichannel Dew Point Temperature Monitoring System for High Energy Physics Applications
The next generation of high-energy physics (HEP) detectors will predominantly be silicon-based. As pixel sensor technology gains momentum and the number of channels surpasses one billion (for a volume of approximately 20 m3) to achieve the high resolution ...
EPFL2023A comprehensive analysis of electron emission from a-Si:H/Al2O3 at low energies
Christophe Ballif, Jonathan Emanuel Thomet, Janina Christine Isabelle Löffler, Samira Alexandra Frey, Mohamed Belhaj
Recently developed microchannel plates (MCPs) based on amorphous silicon offer potential advantages with respect to glass based ones. In this context, secondary electron emission (SEE) at very low energies below 100 eV has been studied for relevant materia ...
IOP Publishing Ltd2023PET REBINNING WITH REGULARIZED DENSITY SPLINES
PET reconstruction algorithms have long relied on sinogram rebinning. However, as detectors grow smaller in a recent wave of cutting-edge scanners, individual sensors no longer accrue hundreds of photons. Instead, most detect a single photon or none at all ...
New York2023Thermal and humidity monitoring in "Cold" silicon-based high energy physics detectors
Sandro Carrara, Andromachi Tsirou, Amar Kapic
As high readout channel density and compact design become the norm for HEP detectors so is the detector cooling at temperatures below the experimental site dewpoint. This increases the importance of humidity and temperature monitoring systems that are also ...
IOP Publishing Ltd2023A Maximum-Likelihood-Based Two-User Receiver for LoRa Chirp Spread-Spectrum Modulation
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Orion Afisiadis, Joachim Tobias Tapparel, Mathieu Pierre Xhonneux
Long Range (LoRa) is an emerging low-power wide-area network technology offering long-range wireless connectivity to Internet of Things (IoT) devices. For energy efficiency reasons, LoRa end nodes implement a nonslotted ALOHA multiple access scheme to tran ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Testing of planar hydrogenated amorphous silicon sensors with charge selective contacts for the construction of 3D-detectors
Sylvain Dunand, Matthew James Large
Hydrogenated Amorphous Silicon (a-Si:H) is a well known material for its intrinsic radiation hardness and is primarily utilized in solar cells as well as for particle detection and dosimetry. Planar p-i-n diode detectors are fabricated entirely by means of ...
2022Design of a low-loss hybrid silicon-organic terahertz field detector
Ileana-Cristina Benea-Chelmus, Alessandro Tomasino, Francesco Bertot
We propose an innovative design for an integrated, low-loss on-chip terahertz (THz) field detector based on hybrid silicon-organic slot waveguides and THz antennas. We perform a numerical study of the dependency of electro-optic interaction on geometrical ...
