Collimation simulations for the FCC-ee

Tatiana Pieloni, Milica Rakic, Bruce Roderik, Guillaume Clément Broggi, Giovanni Iadarola, Félix Simon Carlier

The collimation system of the Future Circular Collider, operating with leptons (FCC-ee), must protect not only the experiments against backgrounds, but also the machine itself from beam losses. With a 17.8 MJ stored energy of the electron and positron beam ...

Simulating supercontinua from mixed and cascaded nonlinearities

Luis Guillermo Villanueva Torrijo, Victor Brasch, Furkan Ayhan, Tobias Herr, Thibault Voumard

Nonlinear optical frequency conversion is of fundamental importance in photonics and underpins countless of its applications: Sum- and difference-frequency generation in media with quadratic nonlinearity permits reaching otherwise inaccessible wavelength r ...

Alignment & stability challenges for FCC-ee

Léon Van Riesen-Haupt, Frank Zimmermann

In order to achieve its ultra-low vertical emittance (1 pm) and high luminosity (of up to 230 x 10(34) cm(-2) s(-1) per collision point), the e(+)e(-) Future Circular Collider (FCC-ee) requires a well-informed alignment strategy, powerful correction method ...

SixTrack V and runtime environment

Igor Zacharov, Riccardo De Maria, Giovanni Iadarola, Dario Pellegrini, Massimo Giovannozzi

SixTrack is a single-particle tracking code for high-energy circular accelerators routinely used at CERN for the Large Hadron Collider (LHC), its luminosity upgrade (HL-LHC), the Future Circular Collider (FCC) and the Super Proton Synchrotron (SPS) simulat ...

Safety In Research Institutions: How to Better Communicate the Risks using Numerical Simulations

Thierry Meyer, Anna Maria Novello, Damien Stricker, Riccardo Iannarelli

What are the risks for the personnel following a gas leak in a laboratory? How effective are the safety measures (gas detection) put in place? Are users aware of how fast they can be exposed? These questions have been approached with the intent to better c ...

2019

A new type of fast luminosity separation scans ("emittance scans") was introduced at the CERN Large Hadron Collider (LHC) in 2015. The scans were performed systematically in every fill with full-intensity beams in physics production conditions at the inter ...

Blade Tio Loss in a Small-Scale Fan

Luca Massera

In this study the influence of tip leakage on the performance of a small-scale fan is evaluated through computational fluid dynamics. ANSYS CFX Release 18.1 is employed for the numerical simulations, the results are extracted, analyzed and compared to the ...

Numerical simulation and sensitivity analysis of a low-Reynolds-number flow around a square cylinder controlled using plasma actuators

François Gallaire, Edouard Boujo, Philippe Meliga

Flow around a square cylinder controlled using plasma actuators (PAs) is numerically investigated by direct numerical simulation in order to clarify the most effective location of actuator installation and to elucidate the mechanism of control effect. The ...
