As far as the tile roofs, they last a long time. It isn't the tile that is the issue, it's the felt (or paper) underneath that gets replaced. Mine is 25 years old, has not been replaced yet. Some neighbors have had theirs redone, but many have not as yet. 04-06-2011, 12:00 AM.
Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion implanters for manufacture of semiconductors, and accelerator mass spectrometers for measurements of rare isotopes such as radiocarbon.
Located near Geneva, Switzerland, the Large Hadron Collider is the largest atom smasher in the world. Particle accelerators are key tools used by physicists to probe the structure of space, time, and matter.nstead of exploring outer space like telescopes, particle accelerators explore the inner space of the atom. The latest and greatest atom smasher is the $5 billion US Dollars Large Hadron Collider (LHC) beneath the Franco-Swiss border near Geneva, Switzerland.
