Combined Bulk and Surface Radiation Damage Effects at Very High Fluences in Silicon Detectors: Measurements and TCAD Simulations / F. Moscatelli (CNR-IMM Bologna) ; D. Passeri (DI of University of Perugia and INFN Perugia) ; A. Morozzi (DI of University of Perugia and INFN Perugia) ; R. Mendicino (DII of University of Trento and TIFPA-INFN) ; G.-F. Dalla Betta (DII of University of Trento and TIFPA-INFN) ; G. M. Bilei (INFN Perugia)
In this work we propose a new combined TCAD radiation damage modelling scheme, featuring both bulk and surface radiation damage effects, for the analysis of silicon detectors aimed at the High Luminosity LHC. In particular, a surface damage model has been developed by introducing the relevant parameters (NOX, NIT) extracted from experimental measurements carried out on p-type substrate test structures after gamma irradiations at doses in the range 10-500 Mrad(Si).

Investigation of beam self-polarization in the future e+e− circular collider / Gianfelice-Wendt, Eliana (Fermi National Accelerator Lab. (US))
The use of resonant depolarization has been suggested for precise beam energy measurements (better than 100 keV) in the eþe− Future Circular Collider (FCC-eþe−) for Z and WW physics at 45 and 80 GeV beam energy respectively. Longitudinal beam polarization would benefit the Z peak physics program; however it is not essential and therefore it will be not investigated here. [...]

Modeling of Radiation Damage Effects in Silicon Detectors at High Fluences HL-LHC with Sentaurus TCAD / D. Passeri (DI of University of Perugia and INFN Perugia) ; F. Moscatelli (CNR-IMM Bologna and INFN Perugia) ; A. Morozzi (DI of University of Perugia and INFN Perugia) ; G.M. Bilei (INFN Perugia)
In this work we propose the application of an enhanced radiation damage model based on the introduction of deep level traps / recombination centers suitable for device level numerical simulation of silicon detectors at very high fluences (e.g. 2.0 1016 1MeV equivalent neutrons/cm2). [...]

Efficient twin aperture magnets for the future circular eþ=e collider / Milanese, Attilio (CERN)
We report preliminary designs for the arc dipoles and quadrupoles of the FCC-ee double-ring collider. After recalling cross sections and parameters of warm magnets used in previous large accelerators, we focus on twin aperture layouts, with a magnetic coupling between the gaps, which minimizes construction cost and reduces the electrical power required for operation.

FRW Bulk Viscous Cosmology with Modified Chaplygin Gas in Flat Space / Saadat, H ; Pourhassan, B
In this paper we study FRW bulk viscous cosmology in presence of modified Chaplygin gas. We write modified Friedmann equations due to bulk viscosity and Chaplygin gas and obtain time-dependent energy density for the special case of flat space..

Interaction and charge transfer between dielectric spheres: exact and approximate analytical solutions / Lindén, Fredrik ; Cederquist, Henrik ; Zettergren, Henning
We present exact analytical solutions for charge transfer reactions between two arbitrarily charged hard dielectric spheres. These solutions, and the corresponding exact ones for sphere-sphere interaction energies, include sums that describe polarization effects to infinite orders in the inverse of the distance between the sphere centers.

Analysis of scalar dissipation in terms of vorticity geometry in isotropic turbulence / Gonzalez, Michel
The mechanisms promoting scalar dissipation through scalar gradient production are scrutinized in terms of vorticity alignment with respect to strain principal axes. For that purpose, a stochastic Lagrangian model for the velocity gradient tensor and the scalar gradient vector is used. [...]

Dimethylsilanone generation from pyrolysis of polysiloxanes filled with nanosized silica and ceria/silica / Kulyk, Kostiantyn ; Zettergren, Henning ; Gatchell, Michael ; Alexander, John D ; Borysenko, Mykola ; Palianytsia, Borys ; Larsson, Mats ; Kulik, Tetiana
Polydimethylsiloxane (PDMS) is a widely used organosilicon polymer often employed in formulations with fine oxide particles for various high temperature applications. Although PDMS is considered to be thermally stable and chemically inert, it is not always clear how the oxide filler influences its thermoresistance, decomposition chemistry and what reactive products are formed in the underlying thermal reactions.

On the origin of intrinsic randomness of Rayleigh-Benard turbulence / Lin, Zhiliang ; Wang, Lipo ; Liao, Shijun
It is of broad interest to understand how the evolution of non-equilibrium systems can be triggered and the role played by external perturbations. A famous example is the origin of randomness in the laminar-turbulence transition, which is raised in the pipe flow experiment by Reynolds as a century old unresolved problem. [...]
