#Technology: A new CERN experiment targets even higher energies (eventually)

High-energy particle beams have multiple uses. In general, a controlled beam of high-energy particles can be used to smash things up – for example tumours or protons – or study them at high resolution, revealing the structure of molecules and materials, or indeed new fundamental physics such as the Higgs boson.

The challenges involved in producing a useful beam are various, and depend on the type of particle and what you want to use the beam for. One common limitation is the size and cost of the machine, and another is the steepness of the accelerating voltage gradient. www.theguardian.com
