Cherenkov diffraction radiation in beam diagnostics - investigation of a potential tool for FCC-ee / Schloegelhofer, Andreas (Technische Universitaet Wien (AT))
In recent years the investigation of Cherenkov diffraction radiation produced by charged particles passing in close vicinity of dielectric material led to promising prototypes for beam diagnostics. In this report, we present a simulation approach to investigate the radiated energy spectrum from Cherenkov diffraction radiation of a single particle and a particle bunch with a focus on its exploitation for the Future Circular Collider for electrons and positrons (FCC-ee).

ECLOUD’18 summary and outlook / Cimino, R (Frascati) ; Zimmermann, F (CERN)
This article reports some highlights from the joint INFN/ARIES workshop ECLOUD’18. We focus on electron-cloud eects in the LHC and at SuperKEKB, predictions for future machines like FCC-hh, HE-LHC and FCC-ee, models and parameters for the secondary-emission yield, recent trends in electron-cloud simulations, mitigation measures, and novel phenomena.

Explainable Deep Learning for Fault Prognostics in Complex Systems: A Particle Accelerator Use-Case / Felsberger, Lukas (Ludwig Maximilians Universitat (DE)) ; Apollonio, Andrea (CERN) ; Cartier-Michaud, Thomas (CERN) ; Todd, Benjamin (CERN) ; Müller, Andreas (Hochschule Darmstadt) ; Kranzlmüller, Dieter (Ludwig-Maximilians-Universität Muenchen) ; Apollonio, Andrea (CERN)
Sophisticated infrastructures often exhibit misbehaviour and failures resulting from complex interactions of their constituent subsystems. Such infrastructures use alarms, event and fault information, which is recorded to help diagnose and repair failure conditions by operations experts. [...]

High frequency response of thick REBCO coated conductors in the framework of the FCC study / Romanov, Artur (CSIC, Catalunya) ; Krkotić, Patrick (CELLS - ALBA, LLS ; Barcelona, Polytechnic U.) ; Telles, Guilherme (CSIC, Catalunya) ; O'Callaghan, Joan (Barcelona, Polytechnic U.) ; Pont, Montse (CELLS - ALBA, LLS) ; Perez, Francis (CELLS - ALBA, LLS) ; Granados, Xavier (CSIC, Catalunya) ; Calatroni, Sergio (CERN) ; Puig, Teresa (CSIC, Catalunya) ; Gutierrez, Joffre (CSIC, Catalunya)
A thorough microwave response study of high temperature superconductors, considered as an alternative beam screen coating, has become integral in the design decisions for CERN’s future research infrastructure. Here, we present the surface resistance $R_{s}$ of various $\text {REBa}_{2}\text {Cu}_{3}\text {O}_{7-x}$ (RE = rare earth) coated conductors available in large scale as a function of magnetic field in a broad temperature range measured by a Hakki–Coleman type resonator with resonant frequency $\nu \approx {8}\,{\text {GHz}}$.

Global electroweak fit in the FCC-ee era / Erler, J (Mexico U. ; U. Mainz, PRISMA) ; Schott, M (U. Mainz, PRISMA)
The top quark and Higgs boson masses have been predicted before their respective discoveries by the global fit of the Standard Model to electroweak precision data. With the Higgs boson discovery and the measurement of its mass, the last missing parameter of the Standard Model has been fixed and thus the internal consistency of the Standard Model can be probed at a new level by comparing direct measurements with the indirect predictions of the global electroweak fit.
