30. Time resolution of an irradiated 3D silicon pixel detector

Talk

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 from 8e14 MeV n$_{eq}$/cm$^2$ to 1.0e16 MeV n$_{eq}$/cm$^2$.
Measurements were conducted using a radioactive source at a temperature of $-$20 and 20 \textdegree C in a bias...

The next generation of inner tracking detectors will require spatial resolution down to 10um, radiation hardness above 10e16Neq/cm^2 together with a temporal resolution in the order to tens of pico seconds.
To face these challenges and overcome limitations of today's technologies, an alternative approach to internal gain through the use of a radiation sensitive doping layer is investigated...

34. Bulk damage study in gamma irradiated n-in-p silicon diodes

Vera Latonova (Czech Academy of Sciences (CZ))

Talk

In this presentation the relation between the leakage current and full depletion voltage to TID will be shown. From the measured I-V and C-V characteristics it is obvious that the dependence of the leakage current with respect to the TID is increasing linearly. On the other hand, the full depletion voltage and thus also the effective doping concentration shows a decreasing trend with higher...

39. Upgraded Proton Irradiation Site at Bonn University

Pascal Wolf (University of Bonn (DE))

Talk

The proton irradiation site at Bonn University has been introduced at previous RD50 workshops. Recently, the setup has been upgraded to minimize fluence fluctuations on the DUT and enable flexible irradiation procedures. The Bonn Isochronous Cyclotron delivers 14 MeV (~12.5 MeV on-device) protons with typical beam currents of 1 𝜇A and beam diameters of a few millimeters to the setup. Enhanced...

27. Radiation tolerance study using 8-inch full-wafer silicon sensors for CMS HGCAL

Oliwia Agnieszka Haluszczak (Wroclaw University of Science and Technology (PL))

Talk

The CMS detector will be upgraded to face a 10-fold increase in integrated luminosity for the High-Luminosity LHC era. Its endcap calorimeters will be replaced by the high-granularity calorimeter (HGCAL). With its unprecedented transverse and longitudinal readout/trigger segmentation, with more than 6M readout channels, HGCAL will facilitate the use of particle-flow calorimetry. Silicon pad...

2. Evaluation of Landau contribution of a single cell 3D 50μm pixel under SPS 120 GeV pion beam

Dr Vagelis Gkougkousis (CERN)

Talk

The proven potential of higher than 10$^{16}$ n$_{eq}$/cm$^{2}$ radiation tolerance that 3D geometries offer, in combination with a small cell approach, makes them an excellent choice for combined precision timing and tracking applications. In this study, timing resolution of a single 50 x 50 μm 3D pixel cell is presented in various temperatures though charged collection measurements in a...
