In high energy projects like particle physics, particle accelerators are used to speed up and collide sub-atomic particles like protons or electrons to break them into smaller, fundamental particles. The short-lived particles are detected and then analyzed to determine how they interact with each other with the ultimate goal of understanding the physical laws of the universe.

As an example, inside the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator, two high-energy beams of protons travel close to the speed of light in opposite directions. These particle beams are guided around an accelerator ring by a strong magnetic field generated by superconducting electromagnets before they collide within sophisticated detectors.


H.C. Starck’s tungsten (W) alloys are used as beam collimators and shields while H.C. Starck’s niobium (Nb) and tantalum (Ta) metals have unique properties that make them the primary choice for superconducting material to create the electromagnetic fields that steer and propel the charged particles to very high speeds.
H.C. Starck offers extrusion services for extruding large diameter superconducting wire bundles.
