abstract:Accelerator physics is a branch of applied physics, concerned with designing, building and operating particle accelerators. As such, it can be circumscribed as the study of motion, manipulation and observation of relativistic charged particle beams and their interaction with accelerator structures by electromagnetic fields.
For a quarter of a century before CERN's Large Hadron Collider (LHC) began working in earnest in 2009 the Tevatron, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, near Chicago, dominated high-energy physics.
Using a combination of modern physics tools--including three-dimensional, high-resolution X-ray, radiocarbon dating with accelerator mass spectrometry, and infrared spectroscopy--the researchers analysed the tooth to determine the age and composition of a resinous filling detected inside.
