The Compact Linear Collider (CLIC) - 2018 Summary Report

The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear $e^+e^-$ collider under development at CERN. Following the CLIC conceptual design published in 2012, this report provides an overview of the CLIC project, its current status, and future developments. It presents the CLIC physics potential and reports on design, technology, and implementation aspects of the accelerator and the detector. CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, respectively. CLIC uses a two-beam acceleration scheme, in which 12 GHz accelerating structures are powered via a high-current drive beam. For the first stage, an alternative with X-band klystron powering is also considered. CLIC accelerator optimisation, technical developments and system tests have resulted in an increased energy efficiency (power around 170 MW) for the 380 GeV stage, together with a reduced cost estimate at the level of 6 billion CHF. The detector concept has been refined using improved software tools. Significant progress has been made on detector technology developments for the tracking and calorimetry systems. A wide range of CLIC physics studies has been conducted, both through full detector simulations and parametric studies, together providing a broad overview of the CLIC physics potential. Each of the three energy stages adds cornerstones of the full CLIC physics programme, such as Higgs width and couplings, top-quark properties, Higgs self-coupling, direct searches, and many precision electroweak measurements. The interpretation of the combined results gives crucial and accurate insight into new physics, largely complementary to LHC and HL-LHC. The construction of the first CLIC energy stage could start by 2026. First beams would be available by 2035, marking the beginning of a broad CLIC physics programme spanning 25-30 years

Thermodynamic Properties of Ni-Sb Alloys

The thermochemical properties of Ni-Sb alloys at 1241, 1363, and 1457 K in the range

Thermodynamic properties of alloys of the binary Sb–Yb system

Mixing enthalpies of melts of the binary Sb–Yb system have been determined for the first time in the ranges 0 < x < 0.155 at 960–1030 K and 0.89 < x < 1 at 1140 K. It has been found that the melts form with great exothermic effects, and the partial enthalpies of the components at infinite dilution are: ΔH¯Sb∞ =–260, ΔH¯Sb∞ =–205 kJ/mol. An ideal associated solution model has been selected to describe the temperature and concentration dependences of thermodynamic properties of the melts, and the parameters of the model have been optimized through self-consistent analysis of the available data on the phase diagram. The model description allows to calculate the Gibbs energies and entropies of mixing of the melts, the activities of the components and the molar fractions of the associates, and the enthalpies and entropies of formation of the solid phases

Thermodynamic properties of Ce–In–Ni ternary alloys

The mixing enthalpies of the liquid Ce–In–Ni ternary alloys have been determined by isoperibol calorimetry along three sections: (CeIn)N (0 < x < 0.11), (InNi)Ce (0 < x < < 0.12), and (CeNi)In (0 < x < 0.03). The mixing enthalpies and activities of components in the Ce–In–Ni ternary alloys are calculated using various models, chosen by critical analysis. The data obtained previously for the binary subsystems are used for calculations, and new experimental data for the ternary systems are employed to verify the reliability of the models. The melts mix with release of significant amounts of heat, and the activities of their components are characterized by negative deviations from ideal solutions
