Development of a Data Concentrator ASIC for the High Luminosity upgrade of the CMS Outer Tracker detector with tracking trigger

Simone Scarfì

With the increasing capabilities of the microelectronics technology, future particle detectors in high energy physics will be able to yield high-level features that are not only simple geometrical positions or energy measurement in the silicon sensors used ...

Verification of selective laser melting heat source models with operando X-ray diffraction data

Steven Van Petegem, Helena Van Swygenhoven, Samy Hocine

The output obtained from operando X-ray diffraction experiments on Ti-6Al-4V is used to verify the accuracy of four FEM models in predicting the temperature evolution of the solidified domain, the cooling rates of the alpha and beta phases, and the influen ...

A novel approach for SPICE modeling of light and radiation effects in ICs

Chiara Rossi

Modeling the interaction of ionizing radiation, either light or ions, in integrated circuits is essential for the development and optimization of optoelectronic devices and of radiation-tolerant circuits. Whereas for optical sensors photogenerated carriers ...

On the Complete Radiation Pattern of a Vertical Hertzian Dipole Above a Low-Loss Ground

Juan Ramon Mosig, Krzysztof Michalski

The complete radiation field pattern of a vertical Hertzian dipole antenna on or above a lossless or low-loss dielectric half-space is studied using a rigorous Sommerfeld formalism. The reflected fields in the air above the interface and the subsurface fie ...

TID Degradation Mechanisms in 16-nm Bulk FinFETs Irradiated to Ultrahigh Doses

Christian Enz

This article investigates the total ionizing dose (TID) degradation mechanisms of 16-nm bulk Si FinFETs at ultrahigh doses. n- and p-FinFETs with several channel lengths are irradiated up to 1 Grad(SiO2) and then annealed for 24 h at 100 degrees C. Irradia ...

Characterization and Modeling of Total Ionizing Dose Effects on Nanoscale MOSFETs for Particle Physics Experiments

Chunmin Zhang

Total ionizing radiation compromises electrical characteristics of microelectronic devices and even causes functional failures of integrated circuits. It has been identified as a potential threat to electronic components, especially those in high-energy ph ...

Monitoring radiation damage in the LHCb Tracker

Mark Tobin, Elena Graverini, Preema Rennee Pais, Pavol Stefko, Achille Mauri

This paper presents the techniques used to monitor radiation damage in the LHCb Tracker Turicensis during the LHC Runs 1 and 2. Bulk leakage currents in the silicon sensors were monitored continuously, while the full depletion voltages of the sensors were ...

Effects of 5 MeV electron irradiation on deep traps and electroluminescence from near-UV InGaN/GaN single quantum well light-emitting diodes with and without InAlN superlattice underlayer

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Camille Haller

The electrical properties, electroluminescence (EL) power output and deep trap spectra were studied before and after 5 MeV electron irradiation of near-UV single-quantum-well (SQW) light-emitting diodes (LED) structures differing by the presence or absence ...

Humidity Sensors for High Energy Physics Applications: A Review

Sandro Carrara, Amar Kapic

Modern silicon-based detectors for high-energy physics operate in an experimental environment with sub-zero temperatures. At those temperatures, even low traces of humidity will produce vapor condensation with damages to the detectors. Monitoring relative ...

A New Concept of Sensor for Ultra-high Levels of Radiation based on Radiation Enhanced Oxidation of Copper Thin-films

Georgi Gorine

The Future Circular Collider (FCC) is the envisioned particle accelerator to be installed in the Geneva area (Switzerland). It could achieve an energy of 100 TeV by colliding proton beams (FCC-hh) travelling through a 100 km tunnel. Unprecedented radiation ...
