The silicon pixel tracking system for the ATLAS experiment at Large Hadron Collider is described and performance requirements are summarized. Detailed descriptions of detector electronics sensors given. design, fabrication, assembly modules presented. Data obtained from test beams as well studies using cosmic rays also discussed.
The Circular Electron Positron Collider (CEPC) is a large international scientific facility proposed by the Chinese particle physics community to explore Higgs boson and provide critical tests of underlying fundamental principles Standard Model that might reveal new physics. CEPC, be hosted in China circular underground tunnel approximately 100 km circumference, designed operate as factory producing electron-positron collisions with center-of-mass energy 240 GeV. collider will also at around...
Generating high-quality text with sufficient diversity is essential for a wide range of Natural Language Generation (NLG) tasks. Maximum-Likelihood (MLE) models trained teacher forcing have consistently been reported as weak baselines, where poor performance attributed to exposure bias (Bengio et al., 2015; Ranzato 2015); at inference time, the model fed its own prediction instead ground-truth token, which can lead accumulating errors and samples. This line reasoning has led an outbreak...
Abstract Antihydrogen atoms with K or sub-K temperature are a powerful tool to precisely probe the validity of fundamental physics laws and design highly sensitive experiments needs antihydrogen controllable well defined conditions. We present here experimental results on production in pulsed mode which time when 90% produced is known an uncertainty ~250 ns. The source generated by charge-exchange reaction between Rydberg positronium atoms—produced via injection positron beam into...
Continual learning, the setting where a learning agent is faced with never ending stream of data, continues to be great challenge for modern machine systems. In particular online or "single-pass through data" has gained attention recently as natural that difficult tackle. Methods based on replay, either generative from stored memory, have been shown effective approaches continual matching exceeding state art in number standard benchmarks. These typically rely randomly selecting samples...
We demonstrate the laser excitation of $n=3$ state positronium (Ps) in vacuum. A combination a specially designed pulsed slow positron beam and high-efficiency converter target was used to produce Ps. Its annihilation recorded by single-shot lifetime spectroscopy. Pulsed level at wavelength $\ensuremath{\lambda}\ensuremath{\approx}205$ nm monitored via Ps photoionization induced second intense pulse $\ensuremath{\lambda}=1064$ nm. About 15% overall emitted into vacuum excited photoionized....
Source localisation and real-time dose verification are at the forefront of medical research in brachytherapy, an oncological radiotherapy procedure based on radioactive sources implanted patient body. The ORIGIN project aims to respond this community’s need by targeting development a multi-point mapping system fibre sensors integrating small volume scintillating material into tip interfaced with silicon photomultipliers operated counting mode. In paper, novel method for selection optimal be...

Abstract Polyamide 6 (PA6) is a material extensively utilized thanks to its high mechanical and thermal properties, but widespread use has raised concerns about environmental impact, especially because polyamides are often coupled with other materials that hinder recyclability. Recycling techniques currently at industrial scale chemical recycling, the temperatures harsh chemicals involved generate impurities complicate process, leading waste disposal. Solvent‐based recycling may offer...
We describe a system designed to re-bunch positron pulses delivered by an accumulator supplied source and Surko-trap. Positron from the are magnetically guided in 0.085 T field injected into region free of magnetic fields through μ-metal terminator. Here positrons temporally compressed, electrostatically accelerated towards porous silicon target for production emission positronium vacuum. Positrons focused spot less than 4 mm FWTM bunches ∼8 ns FWHM. Emission vacuum is shown single shot...
