HEP micro-strip technology • (2 -D detectors are still at cutting edge…) • 1 -D detectors/readout well established. – Single/double sided; various geometries; AC/DC coupled; … • Silicon Strip Detectors are very mature technology – several manufacturers • Readout Chips for Strip detectors mature technology, available, customized or off-the-shelf. – Many variants, much experience. • Applications of this technology are now widespread. – A lot can be done without in-house chip development. • Participation in HEP detector development provides a great jumping off point for such applications, ( BUT not essential for getting value out of this spin-off. ) 22 nd June, 2004 New Zealand - Australia Semiconductor Instrum'n W'kshop 2
