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...
We have used coherent Smith-Purcell radiation (cSPr) in order to determine the temporal profile of sub-ps long electron bunches at Facility for Advanced Accelerator Experimental Tests, SLAC. The measurements reported here were carried out June 2012 and April 2013. rms values bunch length varied between 356 604 fs, depending on accelerator settings. resolution system was limited by range detectable wavelengths which was, turn, determined choice grating periods these experiments achievable...

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...
We discuss the possibility of creating novel research tools by producing and storing highly relativistic beams ionised atoms in CERN accelerator complex, exciting their atomic degrees freedom with lasers to produce high-energy photon beams.Intensity such would be several orders magnitude higher than offered presently operating light sources, particularly interesting γ-ray energy domain 0.1-400 MeV.In this range, high-intensity can used secondary polarised electrons, positrons, muons,...
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...
The need to achieve high energies in particle accelerators has led the development of new accelerator technologies, resulting higher beam intensities and more compact devices with stronger accelerating fields. In such scenarios, beam-loading effects occur, intensity-dependent gradient reduction affects accelerated as a consequence its interaction surrounding cavity. this study, power-diffusive partial differential equation is derived account for effect. Its numerical resolution been...
Protons and heavy-ion beams at unprecedented energies are brought into collisions in the CERN Large Hadron Collider (LHC) for high-energy experiments. The LHC multistage collimation system is designed to provide protection against regular abnormal losses order reduce risk of quenches superconducting magnets as well keeping background experiments under control. Compared protons, beam runs more challenging despite lower stored energies, because efficiency cleaning with heavy ions has been...
The electron amplification and transport within a photomultiplier tube (PMT) has been investigated by developing an in-house Monte Carlo simulation code. secondary emission in the dynodes is implemented via effective model Modified Vaughan's model, whereas computed with Boris leapfrog algorithm. PMT gain, rise time transit have studied as function of supply voltage external magnetostatic field. A good agreement experimental measurements using Hamamatsu R13408-100 was obtained. simulations...
In the scope of Physics Beyond Colliders studies, gamma-factory initiative proposes use partially stripped ions as a driver new type high-intensity photon source in CERN Large Hadron Collider (LHC). 2018, LHC accelerated and stored Pb20881+ for first time. The collimation system efficiency recorded during this test was found to be prohibitively low, so that only very low-intensity beam could without risk triggering dump when regular, minor losses occur. worst were localized dispersion...
The fourth one-month Pb-Pb collision run brought LHC Run 2 to an end in December 2018. Following the tendency reduce dependence on configuration of preceding proton run, a completely new optics cycle with strongest ever focussing at ALICE and LHCb experiments was designed rapidly implemented, demonstrating maturity collider’s operating modes. Beam-loss monitor thresholds were carefully adjusted provide optimal protection from multiple loss mechanisms heavy-ion operation. A switch basic...
UFOs (“Unidentified Falling Objects”) are potentially a major luminosity limitation for nominal LHC operation. With large-scale increases of the BLM thresholds, their impact on availability was mitigated in second half 2011. For higher beam energy and lower magnet quench limits, problem is expected to be considerably worse, though. Therefore, 2011, diagnostics UFO events were significantly improved, dedicated experiments measurements laboratory made complemented by FLUKA simulations...
The Gamma Factory project offers the possibility of creating novel re- search tools by producing relativistic beams highly ionised atoms in CERN’s accelerator complex and exciting their atomic degrees freedom lasers to produce strongly collimated high-energy photon beams. Inten- sity such would exceed several orders magnitude ones offered presently operating light sources, particularly interest- ing energy domain from about 100 keV above 400 MeV. In this regime, high-intensity can be used...
Abstract The beam aperture of a particle accelerator defines the clearance available for circulating beams and is parameter paramount importance performance. At CERN Large Hadron Collider (LHC), knowledge control crucial because nominal proton carry an energy 362 MJ stored in superconducting environment. Even tiny fraction losses could quench magnets or cause severe material damage. Furthermore, circular collider, performance terms peak luminosity depends to large extent on inner triplet...

In high intensity and energy colliders, such as the CERN Large Hadron Collider (LHC) its future high-luminosity upgrade, interactions between two beams around different interaction points impose machine performance limitations. fact, their effect reduces beam lifetime, therefore, collider’s luminosity reach. Those are called beam-beam long-range (BBLR) interactions, a possible mitigation of using dc wires was proposed for first time in early 2000’s. This solution is currently being studied...
