Abstract

To cope with the unprecedented high radiation level at the luminosity up-grade of the LHC (sLHC), novel tracking detectors are investigated. Among these, 3D silicon detectors constitute a promising option. By etching columnar electrodes of both doping types into the sensor, the distance for depletion and charge collection is decoupled from the sensor thickness. Thus, two of the main effects of radiation damage in silicon (increasing depletion voltage and trapping) can be significantly reduced. Since the process technology of 3D is very challenging, modified designs, such as 3D-DDTC detectors (double-sided, double type column), are under investigation. Preliminary results of test beam measurements performed at the CERN SPS with 3D-DDTC strip detectors produced by FBK-IRST in Trento, Italy, are presented.
