Optical trapping with superfocused high-M2 laser diode beam [PDF]

open access: yes, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.

Measurements of the beam-beam interaction at PEP-II [PDF]

open access: yesPACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002
The beam-beam interaction is one of the performance limitations at PEP-II. The peak luminosity in PEP-II has reached 3.4 /spl times/ 10/sup 33//cm/sup 2//s with 693 bunches with a positron current of 1.6 A and an electron current of 0.84 A. The beam-beam tune shift limits have exceeded 0.06 horizontally and 0.03 vertically.

The MICE Muon Beam on ISIS and the beam-line instrumentation of the Muon Ionization Cooling Experiment [PDF]

open access: yes, 2012
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of ionization cooling as a technique for the reduction of the phase-space volume occupied

A study on beam-beam interactions for BTCF [PDF]

open access: yesProceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002
A study on beam-beam interactions in the proposed Beijing Tau-Charm Factory (BTGF) is carried out. Various parameters of the collider, such as tunes, beam-beam parameters, bunch length, beta functions at the interaction point (IP), crossing angle and vertical dispersion at IP, are examined.

Junctophilins 1, 2, and 3 all support voltage-induced Ca2+ release despite considerable divergence [PDF]

open access: yes, 2022
In skeletal muscle, depolarization of the plasma membrane (PM) causes conformational changes of the calcium channel CaV1.1 that then activate RYR1 to release calcium from the SR.

Operational results with fast automatic beam-based LHC collimator alignment [PDF]

open access: yes, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.

Simulations of beam-beam and beam-wire interactions in RHIC

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2009
The beam-beam interaction is one of the dominant sources of emittance growth and luminosity lifetime deterioration. A current-carrying wire has been proposed to compensate long-range beam-beam effects in the LHC and strong localized long-range beam-beam ...
