Toward a brightness upgrade to the SwissFEL: A high gradient traveling-wave rf photogun

Mike Seidel, Paolo Craievich, Sven Reiche, Anastasiya Magazinik

The first generation of S-band injectors for free-electron lasers has illustrated high reliability and performance by driving the latest generation of high brightness machines. However, the ultimate electron beam brightness of these devices is limited by t ...

Resonators with tailored optical path by cascaded-mode conversions

Ileana-Cristina Benea-Chelmus, Marco Piccardo

Optical resonators enable the generation, manipulation, and storage of electromagnetic waves. The physics underlying their operation is determined by the interference of electromagnetic waves, giving rise to the resonance spectrum. This mechanism causes th ...

Simulation and experimental study of proton bunch self-modulation in plasma with linear density gradients

Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Yanis Andrebe, Riccardo Agnello, Falk Hans Braunmüller, Christine Stollberg, Sun Hee Kim, Alban Sublet

We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation results agree with the experimental results reported [F. Braunmller, T. Nechae ...

Quantum-Limited Directional Amplifiers with Optomechanics

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth

Directional amplifiers are an important resource in quantum-information processing, as they protect sensitive quantum systems from excess noise. Here, we propose an implementation of phase-preserving and phase-sensitive directional amplifiers for microwave ...

Continuously Fed Density Currents Over Porous Bed

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sara Venuleo

Gravity currents impact significantly the environment and human's life. Understanding their internal structure and their dynamics is fundamental for modelling purposes. In this study we observe experimentally how bed porosity affects the dynamics of densit ...
