Scotch argus Scotch argus The Scotch argus ("Erebia aethiops") is a butterfly of the family Nymphalidae. In spite of its English name "argus", it is not a close relation of the brown argus nor the northern brown argus. Subspecies include: "Erebia aethiops" is widespread in the Palaearctic ecozone, including most of Europe, the Alps and Apennines, Balkans, Asia Minor, the Urals, and the Caucasus. English colonies are found at Arnside Knott and Smardale Gill both in Cumbria. This species is found in most of northern Scotland, and in western areas in south Scotland. In Europe and Russia, these butterflies prefer the edge
Argus laser groups of amplifiers and spatial filters arranged along the beamlines, each one boosting power until it reached a total of about 1 kilojoule and 1-2 terawatts per beam. These intensities would have been impossible to achieve without the use of spatial filtering. Argus was designed primarily to characterize large laser beamlines and laser-target interactions, there was no attempt to actually achieve the fusion ignition state in the device as this was understood to be impossible at the energies Argus was capable of delivering. Argus however, was used to further explore higher yields of the so-called "exploding pusher" type targets and
