27-kilometer in circumference

Using the LHC in the circular tunnel with a circumference of 27-kilometer, the CERN scientists detected various types of particles, produced by the collisions of squeezed and accelerated 2 proton beams (with 0.02mm in diameter). Finally, the analysis of the results confirmed the discovery of the Higgs boson!

The ATLAS to Detect the Particle

Two Toshiba supplied devices played key roles in discovering the Higgs boson. The ATLAS, installed in the LHC, detects particles at collision points. The detector is a massive device with 44 meters in length, 22 meters in height and 7,000 tons in weight. The ATLAS is equipped with the superconducting solenoid in its center so that a magnetic field, essential for detecting the particles, is to be generated. In addition, at the front and back of the ATLAS, “superconducting quadrupole magnets,” which squeeze proton beams into a single point, are installed.


Toshiba supplied the following two types of magnets installed in the LHC, (1) installed in the front and back of the collision points, "superconducting quadrupole magnets (MQX-A)" squeeze the proton beams into a single point, and (2) installed in the ATLAS detector, "Superconducting Solenoid (i.e. ATLAS Central Solenoid)" generates magnetic fields, which detect particles produced by the proton beam collisions.

The Higgs boson was discovered through the experiments at the CERN

The "superconducting quadrupole magnets" squeeze proton beams into a single point. Making collisions of these beams, the particles are generated and then sorted out in the magnetic fields, created by the "superconducting solenoid." The Higgs boson was finally discovered among numerous particles generated through such processes.


In these experiments, the scientists made collisions of proton beams, which diameters were squeezed into the 1/5 width of human hair.
