To study the emittance growth of beam merging, the LBNL scientists injected 119 beamlets into an electrostatic quadrupole channel.
The researchers can thus generate a collection of beamlets, "each one consisting in the time domain, according to theory and simulations, of a single attosecond pulse," Quere says - which produces an ideal light source for attosecond pump-probe experiments.
