Abstract This Technical Design Report presents a detailed description of all aspects the LUXE (Laser Und XFEL Experiment), an experiment that will combine high-quality and high-energy electron beam European with high-intensity laser, to explore uncharted terrain strong-field quantum electrodynamics characterised by both high energy intensity, reaching Schwinger field beyond. The further implications for search physics beyond Standard Model are also discussed.
In this paper we review the physics opportunities at linear $e^+e^-$ colliders with a special focus on high centre-of-mass energies and beam polarisation, take fresh look various accelerator technologies available or under development and, for first time, discuss how facility equipped technology mature today could be upgraded of tomorrow to reach much higher and/or luminosities. addition, will detectors alternative collider modes, as well beyond-collider experiments R\&D facilities part...
A novel scheme for the focusing of high-energy leptons in future linear colliders was proposed 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This has many advantageous properties over previously studied schemes, including being significantly shorter a given energy having better bandwidth. Experimental results from ATF2 accelerator at KEK are presented that validate operating principle such by demonstrating demagnification 1.3 GeV electron beam down to below 65 nm height...

The magnetostatic field of a finite solenoid with infinitely thin walls carrying dc current oriented in the azimuthal direction is calculated everywhere space terms complete elliptic integrals by direct integration Biot–Savart law. solution particularized near axis and midplane perpendicular to obtaining expressions that agree some typical approximations are made introductory courses electromagnetism or technical literature. range validity these has been studied comparing them obtained...
Dielectric Assist Accelerating (DAA) structures based on ultralow-loss ceramic are being studied as an alternative to conventional disk-loaded copper cavities. This accelerating structure consists of dielectric disks with irises arranged periodically in metallic working under the TM 02 - π mode. In this paper, numerical design S-band DAA for low beta particles, such protons or carbon ions used Hadrontherapy treatments, is shown. Four materials different permittivity and loss tangent well...

High-Gradient accelerating cavities are one of the main research lines in development compact linear accelerators. However, operation such is currently limited by non-linear electromagnetic effects that intensified at high electric fields, as RF breakdowns, dark currents and radiation.
