Description

For the CMS-TOTEM Precise Proton Spectrometer, tracking and timing detectors will be installed next year along the LHC beamline at ~$220$ m from the CMS interaction point. To measure protons scattered at very small angles, detectors will be placed within Roman Pots at a few mm from the LHC beam. Tracking detectors are supposed to receive an irradiation fluence up to $5x10^{15}$ p/cm$^2$. The chosen technology, capable to stand this irradiation level, is $3$D pixel sensor, where columnar electrodes ensure extremely good radiation hardness. Results of laboratory and test beam measurements will be presented for FBK $3$D silicon pixel detectors for CMS. In particular, $1\!$E sensors (single readout electrode for each pixel), coming from the same wafers of the ATLAS-IBL production, read out by the new PSI$46$ digital chip developed for the Phase I upgrade of the CMS silicon pixel detector, have been tested on a $120$ GeV proton beam at Fermilab, before and after being irradiated with $23$ MeV protons at KIT, within the AIDA project, to different fluences up to $1x10^{16}$ n$_{eq}$/cm$^2$. Laboratory measurements and the calibration and optimization of the readout chip were performed in Torino.
