Further improvement of the Telescope Chip performances

The Telescope Chip (TC, alias MIMOSA-26) already equips the EUDET beam telescope since 2009. We have used the extra year to explore a new substrate which promises better performances especi ally in term of radiation tolerance. This study was done in two steps: a repl ication of the TC (UTC, Updated Telescope Chip) on this new substrate to ob serve the benefits and a new version of the IDC (Intermediate Digital Chip) to improve the pixel architecture.
