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 ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Absolute luminosity measurements with the LHCb detector at the LHC [PDF]

, 2012
Absolute luminosity measurements are of general interest for colliding-beam experiments at storage rings. These measurements are necessary to determine the absolute cross-sections of reaction processes and are valuable to quantify the performance of the ...

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

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

Stratonovich expansion and beam-beam interaction [PDF]

Proceedings of the 1989 IEEE Particle Accelerator Conference, . 'Accelerator Science and Technology, 2003
A general approach is proposed for the study of coherent phenomena in electron storage rings due to a localized nonlinear force. The approach is based on expanding the distribution function into a series using generalized Hermite polynomials in two dimensions (Stratonovich expansion).

Incoherent pair generation in a beam-beam interaction simulation [PDF]

Physical Review Special Topics - Accelerators and Beams, 2006
This paper deals with two topics: the generation of incoherent pairs in two beam-beam simulation programs, GUINEA-PIG and CAIN, and the influence of the International Linear Collider (ILC) beam parameter choices on the background in the micro–vertex detector (VD) induced by direct hits. One of the processes involved in incoherent pair creation (IPC) is

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Beam breakup growth and reduction experiments in long‐pulse electron beam transport [PDF]

, 1994
The results of an experimental program whose sole objective is to investigate the cumulative beam breakup instability (BBU) in electron beam accelerators are presented. The BBU growth rate scalings are examined with regard to beam current, focusing field,
