The High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC) will require new high-radiation tolerant silicon pixel sensors for the innermost layers of the CMS experiment tracking detectors, which should be capable of withstanding fluences up to 2.3E16 neq/cm2.
A comprehensive overview of the results obtained in beam test experiments with FBK and CNM 3D pixel sensors interconnected...
The High Luminosity program of the Large Hadron Collider (HL-LHC) will improve the performance of the accelerator by increasing the instantaneous luminosity $\mathcal{L}$ up to 7.5$\cdot$ 10$^{34}$ cm$^{-2}$ s$^{-1}$, with an average of 200 proton-proton collisions per beam-crossing. An upgrade of the ATLAS detector is needed to cope with the harsher radiation levels and with a much higher...
The proven radiation hardness of silicon 3D devices up to fluences of $1 \times 10^{17}\;n_{eq}/cm^{2}$ makes them an excellent choice for next generation trackers, providing $<10\;\mu m$ position resolution at a high multiplicity environment. The anticipated pile-up increase at HL-LHC conditions and beyond, requires the addition of < 50 ps per hit timing information to successfully resolve...
We present performance tests on irradiated 3D-trench silicon sensors, developed within the TimeSPOT project. The tests were performed in different experimental conditions and at different fluences, both in the laboratory and in test-beam at SPS, CERN. The tests show excellent time resolution (around 10 ps) and nominal geometric efficiency (around 99%) of such sensors up to the maximum tested...
