Spinning Black Holes as Particle Accelerators [PDF]
, 2010 It has recently been pointed out that particles falling freely from rest at infinity outside a Kerr black hole can in principle collide with arbitrarily high center of mass energy in the limiting case of maximal black hole spin.

Development of a novel approach for construction of high gradient braze-free S-band cavities
Scientific Reports, 2021 Vacuum breakdown is one of the main limitations to the operating accelerating gradient in radio frequency linear accelerators. Recent studies of copper cavities have been shown that harder copper conditions more quickly and can reach higher accelerating ...

Review of Quality Optimization of Electron Beam Based on Laser Wakefield Acceleration
Photonics, 2022 Compared with state-of-the-art radio frequency accelerators, the gradient of laser wakefield accelerators is 3–4 orders of magnitude higher. This is of great significance in the development of miniaturized particle accelerators and radiation sources ...

Machine Protection and Interlock Systems for Circular Machines - Example for LHC [PDF]
, 2016 This paper introduces the protection of circular particle accelerators from accidental beam losses. Already the energy stored in the beams for accelerators such as the TEVATRON at Fermilab and Super Proton Synchrotron (SPS) at CERN could cause serious ...

Particle Acceleration Mechanisms [PDF]
International Astronomical Union Colloquium, 1994 AbstractHigh-energy particle acceleration is observed to proceed in a diverse variety of astrophysical sites ranging from the terrestrial aurorae to the most distant quasars. Particle acceleration is a fairly common channel for the release of large-scale kinetic, rotational, and magnetic energy.

Evaluation of MLC Thickness and Composite Effects on Collimation Parameters using EGSnrc and IAEA Phase Space Data [PDF]
Journal of Biomedical Physics and Engineering, 2020 Background: Recently, multileaf collimators (MLC) have become an important part of any LINAC collimation system because they reduce the treatment planning time and improve the conformity.

Automation and control of laser wakefield accelerators using Bayesian optimization
Nature Communications, 2020 Laser wakefield accelerators are compact sources of ultra-relativistic electrons which are highly sensitive to many control parameters. Here the authors present an automated machine learning based method for the efficient multi-dimensional optimization ...

Terahertz-driven linear electron acceleration [PDF]
, 2015 The cost, size and availability of electron accelerators is dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency (RF) accelerating structures operate with 30-50 MeV/m gradients. Electron accelerators driven with

Particle Acceleration Mechanisms
Space Science Reviews, 2008 We review the possible mechanisms for production of non-thermal electrons which are responsible for non-thermal radiation in clusters of galaxies. Our primary focus is on non-thermal Bremsstrahlung and inverse Compton scattering, that produce hard X-ray emission.
