Observation of self-accelerating Bessel-like optical beams along arbitrary trajectories [PDF]
, 2013 We experimentally demonstrate self-accelerating Bessel-like optical beams propagating along arbitrary trajectories in free space. With computer generated holography, such beams are designed to follow different controllable trajectories while their main ...

Beam-Beam Simulations for Double-Gaussian Beams [PDF]
Proceedings of the 2005 Particle Accelerator Conference, 2006 Electron cooling together with intra-beam scattering results in a transverse distribution that can best be described by a sum of two gaussians, one for the high-density core and one for the tails of the distribution [1]. Simulation studies are being performed to understand the beam-beam interaction of these double-gaussian beams.

Volkov solution for two laser beams and ITER [PDF]
, 2005 We find the solution of the Dirac equation for two plane waves (laser beams) and we determine the modified Compton formula for the scattering of two photons on an alectron.

Beam-beam effects in RHIC [PDF]
, 2012 In this article we review the beam-beam effects in the polarized proton runs in the Relativistic Heavy Ion Collider (RHIC). The operational observations, limitations, and the next luminosity goal are presented and discussed. With an upgraded polarized proton source, the proton bunch intensity will be increased from 1.7 × 10 up to 3.0 × 10.

Nonuniform currents and spins of relativistic electron vortices in a magnetic field [PDF]
, 2017 We present a relativistic description of electron vortex beams in a homogeneous magnetic field. Including spin from the beginning reveals that spin-polarized electron vortex beams have a complicated azimuthal current structure, containing small rings of ...

, 1983 The subject of beam-beam instability has been studied since the invention of the colliding beam storage rings. Today, with several colliding beam storage rings in operation, it is not yet fully understood and remains an outstanding problem for the storage ring designers.

Merging beam-beam interaction [PDF]
Proceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 2003 A new type of particle collisions is considered. In merging collisions two comoving beams intersect each other at small angle to provide low collision energy required for nuclear fusion experiments. An expression for luminosity is obtained. It is shown that luminosity has a maximum value depending on particle velocity.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
