Academic text (2000) -
The easiest way to make a particle beam is to let the particles carry an electric charge so that electrostatic or magnetic forces can be used to provide the boost.
Academic text (2000) -
Since neutrinos from the Sun and from supernovae travel astronomical distances before they reach the Earth, experiments performed with these particle beams are sensitive to weak interaction phenomena that require long path lengths for their effects to occur.
Academic text (1990) -
However, neutrinos from the Sun and from supernovae provide cosmic particle beams for probing the weak interactions of particles with energies and on time scales that cannot be achieved with traditional laboratory experiments.
Academic text (1990) -
To conduct the experiment, the researchers focused the particle beam on a specific material to observe its properties.

Morphology
The compound 'particle beam' directly combines 'particle' (a very small physical bit) with 'beam' (a directed stream or shaft), so the meaning 'a focused stream of particles' is transparently derivable from its parts. This follows a common noun-noun composition pattern found across languages, making it readily understandable to a B1 learner who knows both constituents.
Etymology
Particle beam comes from the idea of tiny particles moving together like a narrow beam of light. So it means a focused 'stream' of particles used to 'target' cells in medicine or objects in experiments.
