Description
LES (Large Electrode System) is the DC system at CERN, used for observations of the gap between electrodes. This system has view ports that allow for different imaging devices to be set up in parallel to observe the breakdown process. Vacuum arcs can often be seen by eye due to relatively high light intensity, but there are other possible sources of light that may exist before a breakdown. Therefore, integrating a spectrometer with the LES would allow for observations of the spectra to be made. This could be used to extract data relating to field emission, plasma or possible surface processes that occur before and during a breakdown.
