Abstract :
The demand for e+e- collisions beyond the LEP 200 energy range up to the TeV region requires the development of linear collider technology and there seems to be international agreement today, that this should be a 2×250 GeV linear accelerator. Different studies around the world concentrate on different designs, all based on partially or non developed technology. The general differences are mainly expressed by the choice of the operating frequency of the RF-power source and the accelerating structure, which varies for the studies (TESLA, SBLC, NLC, JLC, VLEPP, CLIC) between 1.3 to 30 GHz. Based on a number of arguments which mainly summarise the availability, the cost optimisation and the experience gained so far with S-Band technology, a 500 GeV S-Band linear collider design has been worked out at DESY
