Abstract

A 100 μm thick silicon detector with 1 mm2 pad readout optimized for sub-nanosecond time resolution has been developed and tested. Coupled to a purposely developed amplifier based on SiGe HBT technology, this detector was characterized at the H8 beam line at the CERN SPS. An excellent time resolution of (106 ± 1) ps for silicon detectors was measured with minimum ionizing particles.

Highlights

  • Sensor layoutThe silicon sensors for this measurement were produced by ADVACAM. They consist of 100 μm thick planar n-on-p2 with readout pads of 800 μm × 800 μm area and a pad spacing of 100 μm
