Muon Collider Forum report

Théodora Cohen Liechti, João Miguel das Neves Duarte, Andrea Wulzer, Wei Li, Xiao Wang, Christoph Herwig

A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the energy frontier. Offering a combination of unprecedented energy collisions in a comparatively clean leptonic environment, a high energy muon collider has the unique ...

Optimizing Dynamic Aperture Studies with Active Learning

Tatiana Pieloni, Ekaterina Krymova, Mike Seidel, Davide Di Croce, 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 ...

Optimization of the Beam Screen for the FCC Injection Kicker Magnets

Agnieszka Chmielinska

The Future Circular Collider for hadrons (FCC-hh) is a proposed high-energy frontier particle accelerator, which would be built in a new ~100 km circumference tunnel and would enable proton-proton collisions at a centre-of-mass energy of 100 TeV. The basel ...

The DAQ and control system for the CMS Phase-1 pixel detector upgrade

Qian Wang, Simone Scarfì, Varun Sharma, Chia-Chun Chen, Konstantin Androsov, Xin Chen, Tian Cheng, Werner Lustermann, Andromachi Tsirou, Andrea Rizzi

In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1 pixel detector features four barrel layers in the central region and three disks per end in the forward regions. The upgraded pixel detector requires an upgraded data ac ...

A novel approach to Landau damping of transverse collective instabilities in future hadron colliders

Michael Schenk

Transverse collective instabilities induced by the beam-coupling impedance of the accelerator structure lead to beam quality degradation and pose a major limitation to the machine performance. Landau damping, a powerful stabilising mechanism that can be em ...
