Finely segmented 3D pixel sensors are being considered for the innermost layer of the Phase-2 Tracker upgrade of CMS due to their intrinsic radiation tolerance and low demanding power consumption. No significant degradation of performance is observed up to fluences of 1e16 neq/cm2.
The innermost layer of the Phase-2 Tracker will be placed as close as 3 cm from the beam and will extend 20...
We report on the measurements of time resolution for double-sided 3D pixel sensors with a single cell of 50 $\mu$m $\times$ 50 $\mu$m and thickness of 285 $\mu$m, fabricated at IMB-CNM and irradiated with reactor neutrons to different radiation doses up to 1e16 MeV n$_{eq}$/cm$^2$.
In my talk I will present the results of the first fabrication of
n-on-n 3D detectors. The sensors have been irradiated with neutrons at
fluences up to 1E17n/cm 1 M-ev/equivalent. Using the TCT set up
available at CNM we have been able to do the measurements before
irradiation both of the charge collection efficiency and the timing
performance using a 50x50 pixel array with a pitch of...
