Impact of beam-beam effects on absolute luminosity calibrations at the CERN Large Hadron Collider
Tatiana Pieloni, Claudia Tambasco
At the Large Hadron Collider (LHC), absolute luminosity calibrations obtained by the van der Meer (vdM) method are affected by the mutual electromagnetic interaction of the two beams. The colliding bunches experience relative orbit shifts, as well as optic ...
New York2024Optimizing Dynamic Aperture Studies with Active Learning
Davide Di Croce, Tatiana Pieloni, Ekaterina Krymova, Massimo Giovannozzi
Dynamic aperture is an important concept for the study of non-linear beam dynamics in circular accelerators. It describes the extent of the phase-space region where a particle's motion remains bounded over a given number of turns. Understanding the feature ...
2024Collimation 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 ...
Iop Publishing Ltd2024Impact of beam-coupling impedance on the Schottky spectrum of bunched beam
Tatiana Pieloni, Nicolas Frank Mounet, Christophe Emmanuel R. Lannoy
The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, bunch profile or synchrotron frequency distribution. However, collective effects, ...
Iop Publishing Ltd2024Data-driven modeling of beam loss in the LHC
Tatiana Pieloni, Ekaterina Krymova, Loïc Thomas Davies Coyle, Michael Schenk
In the Large Hadron Collider, the beam losses are continuously measured for machine protection. By design, most of the particle losses occur in the collimation system, where the particles with high oscilla-tion amplitudes or large momentum error are scrape ...
FRONTIERS MEDIA SA2023A Novel Method for Detecting Unidentified Falling Object Loss Patterns in the LHC
Frédéric Blanc, Davide Di Croce, Tatiana Pieloni, Jorg Wenninger, Loïc Thomas Davies Coyle
Understanding and mitigating particle losses in the Large Hadron Collider (LHC) is essential for both machine safety and efficient operation. Abnormal loss distributions are tell- tale signs of abnormal beam behaviour or incorrect machine configuration. By ...
Journals of Accelerator Conferences Website (JACoW) 2022LHC Schottky Spectrum from Macro-Particle Simulations
Tatiana Pieloni, Nicolas Frank Mounet, Christophe Emmanuel R. Lannoy
We introduce a method for building Schottky spectra from macro-particle simulations performed with the PyHEADTAIL code, applied to LHC beam conditions. In this case, the use of a standard Fast Fourier Transform (FFT) algorithm to recover the spectral conte ...
JACoW Publishing2022Design of a Collimation Section for the FCC-ee
Tatiana Pieloni, Bruce Roderik, Frank Zimmermann
The design parameters of the FCC-ee foresee operation with a total stored beam energy of about 20 MJ, exceeding those of previous lepton colliders by almost two orders of magnitude. Given the inherent damage potential, a halo collimation system is studied ...
JACoW Publishing2022Spin Polarization Simulations for the Future Circular Collider e⁺e⁻ using BMAD
Tatiana Pieloni, Léon Van Riesen-Haupt, Félix Simon Carlier, Yi Wu
Measurements of particle properties with unprecedented accuracy in the Future Circular Collider e⁺e⁻ (FCC-ee) are reliant on the high precision center-of-mass energy calibration, which could be realized via resonant depolarization measurements. The obtaina ...
JACoW Publishing, Geneva, Switzerland2022Towards Beam-Beam Simulations for FCC-ee
Xavier Buffat, Tatiana Pieloni, Mike Seidel, Giovanni Iadarola, Péter Kicsiny
The FCC-ee (Future Circular Collider) lepton collider is currently the most favored next generation research infrastructure project at CERN, aimed at studying properties of standard model particles with the highest precision ever. The chosen parameters of ...
