Erosion mechanisms during abrasive waterjet machining: Model microstructures and single particle experiments

The erosion mechanisms during abrasive waterjet (AWJ) machining have been examined for a variety of materials. However, no systematic study has considered the effect of the microstructure property relationship on the erosion mechanisms in metals. In this w ...

Monte Carlo Modeling of Crystal Channeling at High Energies

Philippe Jean Schoofs

Charged particles entering a crystal close to some preferred direction can be trapped in the electromagnetic potential well existing between consecutive planes or strings of atoms. This channeling effect can be used to extract beam particles if the crystal ...

Irreversible bimolecular reactions with inertia: from the trapping to the target setting at finite densities

Giuseppe Foffi, Francesco Piazza

We investigate numerically pseudo-first-order irreversible bimolecular reactions of the type A + B -> B between hard spheres undergoing event-driven Brownian dynamics. We study the encounter rate and the survival probability of A particles as functions of ...

Tunneling and percolation transport regimes in segregated composites

Peter Ryser, Claudio Grimaldi, Biagio Nigro

We consider the problem of electron transport in segregated conductor-insulator composites in which the conducting particles are connected to all others via tunneling conductances, thus forming a global tunneling-connected resistor network. Segregation is ...

Microfluidic integrated hollow photonic crystal cavities for single particle and resonant field interaction

Romuald Houdré, Nicolas Maxime André Descharmes, Ulagalandha Perumal Dharanipathy, Zhaolu Diao

A microfluidic-integrated single particle sensor based on hollow photonic crystal cavities is reported. The interaction relies on the reversible resonance frequency shift induced by a dielectric particle near the cavity. ...

Transport properties of nonhomogeneous segregated composites

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Gianluca Ambrosetti, Biagio Nigro

In conductor-insulator composites in which the conducting particles are dispersed in an insulating continuous matrix the electrical connectedness is established by interparticle quantum tunneling. A recent formulation of the transport problem in these kind ...

Commissioning of the LHCb Inner Tracker and Measurement of V°-Particle Production in pp Collisions at 0.9 TeV

Mathias Oleg Knecht

The Large Hadron Collider (LHC) at CERN near Geneva is an accelerator designed to collide protons at a centre-of-mass energy of √s = 14 TeV. It is operational since November 2009 and has delivered collisions up to an energy of √s = 7 TeV in 2010. The LHCb ...

Percolation-to-hopping crossover in conductor-insulator composites

Claudio Grimaldi, Gianluca Ambrosetti

Here, we show that the conductivity of conductor-insulator composites in which electrons can tunnel from each conducting particle to all others may display both percolation and tunneling (i.e., hopping) regimes depending on few characteristics of the compo ...

Construction of the Inner Tracker and Sensitivity to the B°s -> [mu][mu] Decay at LHCb

Marc-Olivier Bettler

LHCb is one of the four main experiments hosted at the Large Hadron Collider (LHC) at CERN. The LHC first started in September 2008 and, after a one-year hiccough, restarted in November 2009. In the course of three weeks, the HEP community witnessed the fi ...

Gyrokinetic simulations of impurity, He ash and alpha particle transport and consequences on ITER transport modelling

Alberto Bottino, Emiliano Fable

The transport of light and heavy impurities, as well as of energetic a particles, produced by the background electrostatic plasma turbulence is investigated by means of linear and nonlinear simulations with three gyrokinetic codes, GS2, GYRO and the recent ...
