“…A strong R&D effort is being made to study radiation hardness on silicon Hamamatsu test samples of different materials (Float Zone, Magnetic Czochralski, epitaxial substrate and oxygen rich ones ([O]> 2 × 10 16 ), different implants (n-in-p and p-in-n) and different thicknesses (300, 200, 100 and 50 µm). Results from irradiation campaigns [9,10] showed promising performances of n-in-p implants, thanks to their higher radiation tolerance with respect to p-in-n. Furthermore, in Magnetic Czochralski materials the collected charge was observed to be independent of the annealing.…”

“…Since the longer the drift distance the higher the charge lost by trapping, two R&D strands have been started for reducing the inter-electrode distance: thin planar sensors and 3D sensors. Thin planar sensors, with thicknesses between 100 and 200 µm, have already shown very promising performances after heavy irradiation [5]. Several submissions are expected this year to study small pixel feasibility, p-spray vs p-stop insulation, radiation tolerance and resolution in beam tests.…”

During the high luminosity phase of the LHC (HL-LHC), the machine is expected to deliver an instantaneous luminosity of 5 × 10 34 cm −2 s −1 . A total of 3000 fb −1 of data is foreseen to be delivered, with the opening of new physics potential for the LHC experiments, but also new challenges from the point of view of both detector and electronics capabilities and radiation hardness. In order to maintain its physics reach, CMS will build a new Tracker, comprising completely new pixel detector and outer tracker. The ongoing R&D activities on both pixel and strip sensors will be presented. The present status of the Inner and Outer Tracker projects will be illustrated, and the possible perspectives will be discussed.
