Definition of beamline
physics
: a beam of particles (such as photons or electrons) emitted from a particle accelerator
The synchrotron uses magnets to guide electrons around a ring that's about the size of a basketball court. Every time an electron turns a corner, so to speak, it emits a photon. The photons fly away from the ring in what are called beamlines. — National Geographic, October 2001
