Luminosity limit due to the beam-beam interactions with or without crossing angle
Physical Review Special Topics. Accelerators and Beams, 2004 In recent high luminosity colliders, the finite crossing angle scheme becomes popular to gain the luminosity with multibunch or long bunch operation. Success of the KEKB factory showed that the finite crossing angle scheme has no problem achieving beam ...

Nonlinear generation of hollow beams in tunable plasmonic nanosuspensions
APL Photonics, 2023 We experimentally demonstrate that a probe beam at one wavelength, although exhibiting a weak nonlinear response on its own, can be modulated and controlled by a pump beam at another wavelength in plasmonic nanosuspensions, leading to ring-shaped pattern

Filling pattern dependence of regenerative beam breakup instability in energy recovery linacs
Physical Review Accelerators and Beams, 2021 Beam breakup instability is a potential issue for all particle accelerators and is often the limiting factor for the maximum beam current that can be achieved.

Beam-beam interaction and high order resonances [PDF]
Conference Record of the 1991 IEEE Particle Accelerator Conference, 2002 There is experimental evidence from SPS, that very high order resonances (an order > 10) can cause particle loss during the beam- beam interaction. These particle loss during the beam-beam interaction. These results can be simulated by tracking a single particle against a round beam.

Beam ion instability: Measurement, analysis, and simulation
Physical Review Special Topics. Accelerators and Beams, 2013 A weak vertical coupled-bunch instability with oscillation amplitude of the order of a few μm has been observed in SPEAR3 at nominal vacuum pressure. The instability becomes stronger with increasing neutral gas pressure as observed by turning off vacuum ...

Strong field processes in beam-beam interactions at the Compact Linear Collider
Physical Review Special Topics. Accelerators and Beams, 2014 The demand for high luminosity in the next generation of linear e^{+}e^{-} colliders necessitates extremely dense beams, giving rise to strong fields at the collision point, and therefore the impact of the field on the physical processes occurring at the

Dust-induced beam losses in the cryogenic arcs of the CERN Large Hadron Collider
Physical Review Accelerators and Beams, 2022 The interaction of dust particles with the LHC proton beams accounts for a major fraction of irregular beam loss events observed in LHC physics operation.

Mitigation of the kink instability in the energy recovery linac based electron-ion collider
Physical Review Special Topics. Accelerators and Beams, 2013 Beam-beam effects in eRHIC, the proposed energy recovery linac (ERL)-based electron-ion collider (EIC) at BNL, have several unique features distinguishing them from those in hadron and lepton colliders.

Beam-beam effects in the Tevatron
Physical Review Special Topics. Accelerators and Beams, 2005 The Tevatron in Collider Run II (2001–present) is operating with 6 times more bunches, many times higher beam intensities and luminosities than in Run I (1992–1995).
