HIGH-INTENSITY ELECTRON STORAGE RINGS¹

In recent years a new generation of electron-positron colliders that will have 10–100 times the luminosity of today's machines has started construction. In a similar time frame, a new generation of high-brightness synchrotron light sources has become operational. The scientific goals for these “particle factories” and light sources are explained briefly, and the machine parameters required to achieve them are indicated. Both the accelerator physics and technology issues that result from the required parameters are discussed to show the challenges involved in such significant extensions of accelerator performance. Examples taken from representative projects are used to illustrate the types of solutions adopted to meet these challenges.
