Recommissioning of the CERN AD Stochastic Cooling System in 2021 after Long Shutdown 2 / Hofle, Wolfgang (CERN) ; Oliveira, Joao Carlos (CERN) ; Carli, Christian (CERN) ; Caspers, Fritz (European Scientific Institute (FR)) ; Dupuy, Bruno (CERN) ; Gamba, Davide (CERN) ; Louwerse, Reinier (CERN) ; Ponce, Laurette (CERN) ; Myklebust, Vebjorn Roed ; Rey, Stephane Franck (CERN) et al.
The power system of the Stochastic Cooling System of the anti-proton decelerator AD at CERN, installed on top of the shielding blocks of the AD ring, was completely dismantled during the long shutdown 2 (LS2) at the end of the 2018 run in order to gain access to the accelerator for magnet consolidation.

Framework for automatic superconducting magnet model generation & validation against transients measured in LHC magnets / Janitschke, Marvin (Technische Universität Berlin)
Superconducting magnet circuits are a key part of particle accelerators. Simulating complex transients occurring in these circuits with dedicated models is crucial to analyze their behavior and assess the impact of failure cases. [...]

Design Study of X-band High Efficiency Klystrons for CLIC / Cai, Jinchi (Lancaster U. ; CERN) ; Syratchev, Igor (CERN)
The design of two X-band high efficiency (HE) Klystrons are presented in this paper. Based on Core Oscillation Method (COM) and coupled-cell output structure topology, 8MW Klystron for Xbox test stand can yield 58% output efficiency with beam perveance of 1.6uP. [...]

Summary of Working Group 8: Advanced and Novel Accelerators for High Energy Physics / Carlsten, B E (Los Alamos) ; Schulte, D (CERN) ; Lu, W (Tsinghua U., Beijing)
We summarize the conclusions from Working Group 8 of the European Advanced Accelerator Concepts workshop in 2019 (EAAC2019) on the suitability and prospects for using advanced and novel accelerator (ANA) technology for future high-energy physics (HEP) applications. We identify the key technology gaps remaining for the main ANA approaches for building future e+/e− linear colliders and estimate the time scales needed to close them. [...]

A Ferroelectric Fast Reactive Tuner (FE-FRT) to Combat Microphonics / Shipman, Nicholas (CERN) ; Bastard, Jeremy (CERN) ; Ben-Zvi, Ilan (Brookhaven) ; Burt, Graeme (Lancaster U.) ; Castilla, Alejandro (Lancaster U.) ; Coly, Marcel (CERN) ; Gerigk, Frank (CERN) ; Jing, Chunguang (Euclid Techlabs, Solon) ; Kanareykin, Alexei (Euclid Techlabs, Solon) ; Macpherson, Alick (CERN) et al.
A prototype Fast Reactive Tuner (FRT) for superconducting cavities has been developed, which allows the frequency to be controlled by application of a potential difference across a newly developed ultra-low loss ferro-electric material residing within the tuner. The tuner operates at room temperature, outside of the cryostat and coupled to the cavity via an antenna and co-axial cable. [...]

Predicting the Trajectory of a Relativistic Electron Beam for External Injection in Plasma Wakefields / Asmus, Felipe Peña (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Velotti, Francesco Maria (CERN) ; Turner, Marlene (CERN) ; Gessner, Spencer (CERN) ; Martyanov, Mikhail (Munich, Max Planck Inst.) ; Bracco, Chiara (CERN) ; Goddard, Brennan (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
We use beam position measurements over the first part of the AWAKE electron beamline, together with beamline modeling, to deduce the beam average momentum and to predict the beam position in the second part of the beamline. Results show that using only the first five beam position monitors leads to much larger differences between predicted and measured positions at the last two monitors than when using the first eight beam position monitors.

Differential Cross Section Measurement of the $pp\rightarrow WH\rightarrow WWW$ Process With the ATLAS Experiment / Hesping, Moritz Elias
In this thesis, a Simplified Template Cross Section (STXS) analysis for the $ pp\rightarrow WH\rightarrow WWW\rightarrow l\nu l\nu l\nu$ process is presented, using final states with no lepton pairs of the same flavor and opposite charge. The analysis uses proton-proton collisions at a center of mass energy of $13~TeV$ with an integrated luminosity of $139~fb^{-1}$, which were measured by the ATLAS detector at the Large Hadron Collider.

RF system challenges for future  ${e}^+ {e}^-$ circular colliders / Brunner, Olivier (CERN) ; Jensen, Erk (CERN) ; Karpov, Ivan (CERN) ; Montesinos, Eric (CERN) ; Peauger, Franck (CERN) ; Syratchev, Igor (CERN)
The RF system is the centrepiece of any future circular lepton collider. In particular, the system is required to support the high intensity beams needed for pushing the luminosity at the lower energy regimes of future energy-frontier circular lepton colliders (e.g. [...]
