Introduction to the Photon Collider

With the International Linear Collider (ILC) on life-support system due to the pull-out of the United Kingdom and the severe funding slash by the US Congress, maybe it is a bit moot to talk about possible experiments at the ILC. Still, it one can always dream of what could have been. The ILC would certainly be the most logical facility to start considering the possibility of having a photon collider. This article gives a rather thorough "introduction" to the physics we gain out of a photon collider.

Ah, the good old days of optimism.....
