Vertex Detectors

It has been widely recognized that the "new physics" results from a high energy collider are related to the detector capabilities, and that future detec- tors must solve the problems presented by the new environment. Vertex detectors, in particular, will have to sustain enormous rates, have a great resistance to radiation damage, while retaining good spatial accuracy. Promising technologies are emerging, and gaseous detectors are improving: this workshop was intended as a point of reference...
