An Open Modelling Approach for Availability and Reliability of Systems - OpenMARS / Penttinen, Jussi-Pekka ; Niemi, Arto (Tampere University of Technology (FI)) ; Gutleber, Johannes (CERN)
This document introduces and gives specification for OpenMARS, which is an open modelling approach for availability and reliability of systems. It supports the most common risk assessment and operation modelling techniques. [...]

HOM power in FCC-ee cavities / Karpov, Ivan (CERN) ; Calaga, Rama (CERN) ; Chapochnikova, Elena (CERN)
This Note summarizes the results of the power loss calculations for FCC-ee machines with 400.79 MHz cavity options. The requirements for the single-cell cavity design and for the operation with beam are obtained from the results for the high-current FCC-ee machine (Z). [...]

Crystal collimator systems for high energy frontier / Sytov, Alexei (Universita di Ferrara & INFN (IT)) ; Tikhomirov, Viktor (Byelorussian State University (BY)) ; Lobko, Alexander (Byelorussian State University (BY))
Crystalline collimators can potentially considerably improve the cleaning performance of the presently used collimator systems using amorphous collimators. A crystal-based collimation scheme which relies on the channeling particle deflection in bent crystals has been proposed and extensively studied both theoretically and experimentally. [...]

Magnetic refrigeration down to 1.6 K for the future circular collider e$^+$e$^-$ / Tkaczuk, Jakub (CEA (FR)) ; Millet, Francois ; Rousset, Bernard (CEA (FR)) ; Duval, Jean Marc (CEA (FR))
High-field superconducting rf cavities of the future circular collider e+e− may require a kW-range superfluid helium refrigeration down to 1.6 K. Magnetic refrigeration operating below 4.2 K can be an alternative to the compression/expansion helium refrigeration. [...]

Impact of process parameters and design options on heat leaks of straight cryogenic distribution lines / Duda, Pawel (Wroclaw University of Technology (PL)) ; Chorowski, Maciej Pawel ; Polinski, J (Wroclaw University of Technology (PL))
The Future Circular Collider (FCC) accelerator will require a helium distribution system that will exceed the presently exploited transfer lines by almost 1 order of magnitude. The helium transfer line will contain five process pipes protected against heat leaks by a common thermal shield. [...]
