The CLIC Potential for New Physics
/ De Blas Mateo, Jorge (Universita e INFN, Padova (IT)) ; Franceschini, Roberto (Universita e INFN Roma Tre (IT)) ; Riva, Francesco (Universite de Geneve (CH)) ; Roloff, Philipp Gerhard (CERN) ; Schnoor, Ulrike (CERN) ; Spannowsky, Michael (University of Durham (GB)) ; Wells, James D (University of Michigan) ; Wulzer, Andrea (CERN) ; Zupan, Jure (University of Cincinnati (US))
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines the benefits of the clean environment of $e^+e^−$ colliders with the possibility of operating at centre-of-mass energies able to probe scales beyond the reach of Large Hadron Collider (LHC) for many scenarios of new physics.

Novel measurement technique for the electromagnetic characterization of coating materials in the sub-THz frequency range
/ Passarelli, Andrea (CERN ; Darmstadt, Tech. U.) ; Bartosik, Hannes (CERN) ; Rumolo, Giovanni (CERN) ; Vaccaro, Vittorio Giorgio (INFN, Naples) ; Masullo, Maria Rosaria (INFN, Naples) ; Koral, Can (INFN, Naples) ; Papari, Gian Paolo (Naples U. ; INFN, Naples) ; Andreone, Antonello (Naples U. ; INFN, Naples) ; Boine-Frankenheim, Oliver (Darmstadt, Tech. U.)
This paper describes a reliable, handy, and inexpensive measurement system to characterize, in the sub-THz frequency range, the coating materials used in the beam pipes of accelerators. The method is based on time domain measurements of an electromagnetic wave passing through a waveguide having a thin central slab, where the coating material is deposited on both sides. [...]

DC vacuum breakdown in an external magnetic field
/ Lebedynskyi, S (Sumy, Inst. Appl. Phys.) ; Karpenko, O (Sumy, Inst. Appl. Phys.) ; Kholodov, R (Sumy, Inst. Appl. Phys.) ; Baturin, V (Sumy, Inst. Appl. Phys.) ; Profatilova, Ia (Sumy, Inst. Appl. Phys. ; CERN) ; Shipman, N (CERN) ; Wuensch, W (CERN)
The subject of the present theoretical and experimental investigations is the effect of the external magnetic field induction on dark current and a possibility of breakdown. The generalization of the Fowler-Nordheim equation makes it possible to take into account the influence of a magnetic field parallel to the cathode surface on the field emission current. [...]

High Power Conditioning of X-Band RF Components
/ Catalán Lasheras, Nuria (CERN) ; Damerau, Heiko (CERN) ; Gerard, Romain Louis (CERN) ; Grudiev, Alexej (CERN) ; Lucas, Thomas (Melbourne U.) ; McMonagle, Gerard (CERN) ; Paszkiewicz, Jan (CERN) ; Pitman, Sam (Lancaster U.) ; Solodko, Anastasiya (CERN) ; Syratchev, Igor (CERN) et al.
As part of the effort to qualify CLIC accelerating struc-tures prototypes, new X-band test facilities have been built and commissioned at CERN in the last years. In this context, a number of RF components have been designed and manufactured aiming at stable operation above 50 MW peak power and several kW of average power. [...]

Status of the Polarix-TDS Project
/ Craievich, Paolo (PSI, Villigen) ; Aßmann, Ralph (DESY) ; Bopp, Markus (PSI, Villigen) ; Braun, Hans-Heinrich (PSI, Villigen) ; Catalán Lasheras, Nuria (CERN) ; Christie, Florian (DESY) ; D'Arcy, Richard (DESY) ; Dorda, Ulrich (DESY) ; Foese, Manon (DESY) ; Ganter, Romain (PSI, Villigen) et al.
A collaboration between DESY, PSI and CERN has been established to develop and build an advanced modular X-band transverse deflection structure (TDS) system with the new feature of providing variable polarization of the deflecting force. This innovative CERN design requires very high manufacturing precision to guarantee highest azimuthal symmetry of the structure to avoid the deterioration of the polarization of the streaking field.

Resistive-Wall Impedance of Insertions for FCC-hh
/ Riemann, Bernard (Dortmund U., DELTA) ; Arsenyev, Sergey (CERN) ; Khan, Shaukat (Dortmund U., DELTA) ; Schulte, Daniel (CERN)
In this work, transverse and longitudinal resistive-wall impedances for beam pipes in the experiment, injection, extraction and RF systems insertion regions of the Future Hadron-Hadron Collider (FCC-hh) are computed based on contributions from different given cross sections of the surrounding (elliptical) chamber parts along the beam path, their temperature-dependent conductivities, and optical functions. An emphasis is placed on the behaviour of transverse impedance in the main experimental regions (A and G), where maximum beta values of $10^4$ to $10^5$ m occur in dependence of the operation mode respectively lattice configuration.
