This chart shows just one of the eight LHC sectors cooled to operating temperatures below 1.9 K. The arc magnets are the main magnets that guide the proton beams around the LHC circumference to the collision points.
The Large Hadron Collider's have been cooled to their superconducting operating temperatures at 1.9 kelvin. The online charts of the temperatures show all eight sectors of the LHC cooled.
This is a major milestone in the restart of the LHC and bodes well for the further operations this year. CERN plans to start circulating the proton beams in November and aims for first collisions sometime after mid-December.
You can read more about the latest status of the LHC in this week's CERN Bulletin.
