TESLA accelerator component. Technician in clean room clothing checking a resonator for use in the TESLA (Tera-electron Volt Energy Superconducting Linear Accelerator). This niobium resonator will be cooled to -271 degrees Celsius, 2 degrees above absolute zero, at which temperature it will become a superconductor. A 33 kilometre path of these will accelerate electrons and positrons (anti- electrons) using magnetic fields, colliding them at the path's centre. This will be used to study the nature of matter in the universe. In addition to this, the facility will be able to create X-ray lasers, which will be able to visualise individual atoms. This work is being done at DESY in Germany.
