Radiation Patterns of RF Wireless Devices Implanted in Small Animals: Unexpected Deformations Due to Body Resonance
Anja Skrivervik, Stéphanie Lacour, Zvonimir Sipus, Mingxiang Gao, German Augusto Ramirez Arroyave, Kangling Wu
One challenge in designing RF wireless bioelectronic devices is the impact of the interaction between electromagnetic waves and host body tissues on far-field wireless performance. In this paper, we investigate a peculiar phenomenon of implantable RF wirel ...
2023500 GHz field-resolved detection in thin-film lithium niobate devices
Ileana-Cristina Benea-Chelmus, Alessandro Tomasino
In this work, we show the coherent reconstruction of terahertz (THz) transients in thin-film lithium niobate integrated photonics circuits. Our devices modulate the intensity of a probe beam guided through a Mach-Zehnder interferometer (MZI) structure, und ...
New York2023Development of microlens-enhanced SiPMs for a radiation-hard scintillating fibre tracker at LHCb
he LHCb experiment at CERN's Large Hadron Collider (LHC) is currently taking data with a newly developed Scintillating Fibre (SciFi) Tracker read out with multichannel silicon photomultipliers (SiPMs). The innermost fibre modules, exposed to the highest ra ...
EPFL2023The X-Point radiating regime at ASDEX Upgrade and TCV
Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Artur Perek, Marco Wischmeier, Bernhard Sieglin
Future fusion reactors require a safe, steady-state divertor operation. With deep divertor detachment, which is typically induced by impurity seeding, the radiation concentrates in a small region at the X-point or on closed flux surfaces above the X-point. ...
ELSEVIER2023Inverse-Designed Narrowband THz Radiator for Ultrarelativistic Electrons
Rasmus Ischebeck, Benedikt Hermann
THz radiation finds various applications in science and technology. Pump-probe experiments at free-electron lasers typically rely on THz radiation generated by optical rectification of ultrafast laser pulses in electro-optic crystals. A compact and cost-ef ...
AMER CHEMICAL SOC2022Microlens-enhanced silicon photomultiplier arrays for LHCb SciFi Tracker Upgrade Ib
Olivier Schneider, Guido Haefeli, Ettore Zaffaroni, Carina Trippl
A large-scale Scintillating Fibre Tracker has been developed and constructed for the current LHCb Upgrade 1. The high radiation by fast neutrons reduces the light yield of the detector in the course of LHC Run 3, and is challenging the tracker's hit detect ...
ELSEVIER2022High-Performance CMOS SPAD-Based Sensors for Time-of-Flight PET Applications
Detecting light, photon by photon, has been possible since the 1930s, with the invention of the photomultiplier tube (PMT). However, it is only since the 1970s, that solid-state single-photon detectors have emerged and only since 2003 that a new technology ...
EPFL2022Sub-10 ps Minimum Ionizing Particle Detection With Geiger-Mode APDs
Edoardo Charbon, Claudio Bruschini, Emanuele Ripiccini, Ming-Lo Wu, Francesco Gramuglia, Carlo Alberto Fenoglio
Major advances in silicon pixel detectors, with outstanding timing performance, have recently attracted significant attention in the community. In this work we present and discuss the use of state-of-the-art Geiger-mode APDs, also known as single-photon av ...
FRONTIERS MEDIA SA2022Machine learning for metallurgy V: A neural-network potential for zirconium
William Curtin, Pandula Manura Liyanage
The mechanical performance-including deformation, fracture and radiation damage-of zirconium is determined at the atomic scale. With Zr and its alloys extensively used in the nuclear industry, understanding that atomic scale behavior is crucial. The defect ...
AMER PHYSICAL SOC2022Excitation of Alfven eigenmodes by fusion-born alpha-particles in D-He-3 plasmas on JET
Henri Weisen, Javier García Hernández
Alfven eigenmode (AE) instabilities driven by alpha-particles have been observed in D-He-3 fusion experiments on the Joint European Torus (JET) with the ITER-like wall. For the efficient generation of fusion alpha-particles from D-He-3 fusion reaction, the ...
