Caption: Jefferson Lab. View of the electron source for the accelerator at the Thomas Jefferson National Accelerator Facility, or Jefferson Lab. A laser (background) is used to illuminate a gallium arsenide (GaAs) photocathode. Electrons emitted by the photoelectric effect are allowed to leave the surface and travel toward an injector, thence into the accelerator. By careful tuning of the laser and manipulation in the z- shaped device at centre, electrons of a specific spin are produced. The spin (polarisation) of the electrons is an important factor in the interactions being studied to investigate the quark nature of matter. Jefferson Lab is at Newport News, Virginia, USA.
