Beam induced vacuum effects in the future circular hadron collider beam vacuum chamber

Lotta Maria Mether

EuroCirCol is a conceptual design study of a post-LHC, Future Circular Hadron Collider (FCC-hh) with 50 TeV of beam energy and 100 km long, which aims to expand the current energy and luminosity frontiers. The vacuum chamber of the FCC-hh will have to cope ...

Electron Cloud and Synchrotron Radiation characterization of technical surfaces with the Large Hadron Collider Vacuum Pilot Sector

Elena Buratin

This PhD thesis presents the experimental study on electron cloud (EC) and synchrotron radiation (SR) phenomena affecting the LHC storage ring performance. These phenomena are one of the major issues of the LHC storage ring, generating beam instabilities, ...

A synchrotron X-ray imaging strategy to map large animal brains

Giorgio Margaritondo, Ying Chen

Mapping the large neural networks of animal and human brains is a fundamental but so far elusive task, because of the massive amount of data and the consequent prohibitively long image taking and processing times. We developed an effective strategy called ...

Magnetic electron collimation in three-dimensional semi-metals

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez

While electrons moving perpendicular to a magnetic field are confined to cyclotron orbits, they can move freely parallel to the field. This simple fact leads to complex current flow in clean, low carrier density semi-metals, such as long-ranged current jet ...

Electronic Population Transfer via Impulsive Stimulated X-Ray Raman Scattering with Attosecond Soft-X-Ray Pulses

Christoph Bostedt, Xiang Li, Andre Al Haddad, Solène Oberli, Siqi Li

Free-electron lasers provide a source of x-ray pulses short enough and intense enough to drive nonlinearities in molecular systems. Impulsive interactions driven by these x-ray pulses provide a way to create and probe valence electron motions with high tem ...

A teaching showcase unveils the links between special relativity and the birth of quantum physics

Giorgio Margaritondo

Quantum effects scale up with the frequency of electromagnetic waves. Therefore, modern synchrotron sources of high-frequency x-rays-that can be visited by students either personally or online-offer an opportunity for a captivating introduction to basic qu ...
