One can reasonably ask the question why not just build a bigger storage ring? Why do we need a linear machine that on the face of it seems much more complex? The concept of a linear collider is not particularly new, and was in fact first proposed by M. Tigner in 1965 in a paper entitled "A Possible Apparatus for Electron Clashing-Experiments ?": While the storage ring concept for providing clashing-beam experiments is very elegant in concept it seems worth-while at the present juncture to investigate other methods which, while less elegant and superficially more complex may prove more tractable. Nuovo Cimento 37 (1965) 1228. So even over thirty years ago it was clear (to some) that the storage ring concept was limited in its energy reach. The reason is due to synchrotron radiation effects and the cost scaling of such facilities.
