These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.
The surface above the PS Booster at CERN. The ring-shaped accelerator is visible as a circular building that rises from the ground.
The Proton Synchrotron Booster (PSB), a synchrotron, is the first and smallest circular proton accelerator in the accelerator chain at the CERNLarge Hadron Collider injection complex.[1] The accelerator was built in 1972, and contains four superimposed rings with a radius of 25 meters. It takes protons with an energy of 50 MeV from the linear acceleratorLinac2 and accelerates them up to 1.4 GeV, ready to be injected into the Proton Synchrotron.
