0 a line of light that shines from a bright object: --
an electron beam
a laser beam
The rabbit stopped, mesmerized by the beam of the car's headlights.
We could just pick out the trail in the weak beam of the flashlight.

Excitation of plasma wave by two laser beams.
Equation ofstate proper ties of high-energydensity matter using intense heavy ion beams with an annular focal spot.
3 ability to describe forward scattering instabilities, not only for mono-energetic photon beams, but also for laser beams with an arbitrary spectral width.
Demonstration of fusion-evaporation and direct-interaction nuclear reactions using high-intensity laserplasma-accelerated ion beams.
The displacement is supposed to be the same in magnitude for all beams of one cone and to be the same for the symmetric cone.
We show it is possible to minimize the rms deviation of the intensity by repointing the beams and an optimum is found.
Different applications require different optimizations of the proton beams.
The approach that has been explored in the past would use a single aper ture for each of the 100 beams of the injector.
