Silicon sensors are commonly used in particle trackers because of their stability
and high spatial resolution in the um range. Inside a strong magnetic field the
ionization is not entering on the electrode hit by the particle, but shifted to
neighboring electrodes because of the Lorentz force in crossed E and B fields,
which lets the ionization drift under a certain angle. This Lorentz...

Concept, simulations, and design of the US patent-pending new detectors with novel electrode configurations will be presented. These detectors can be ultral radiation hard for applications in extremely high radiation environment such as sLHC, and for applications in photon sciences.

3D-Si sensors fabricated at FBK-irst with the Double-side Double Type Column approach and columnar electrodes only partially etched through p-type substrates were tested in laboratory and in a 1.4 Tesla magnetic field with a 180 GeV pion beam at CERN SPS.
We'll present leakage current and noise measurements, results of functional tests with gamma-ray sources, charge collection tests with...

Detectors in the 3D-DDTC (double-sided double type column) layout combine the intrinsically radiation hard design of 3D detectors with a simplified processing technology. This talk presents results of 3D-DDTC detectors obtained in beam test measurements with high-energy particles at the CERN SPS. The Silicon Beam Telescope (SiBT), provided by the University of Helsinki, was utilised to measure...

Electrical simulations have been performed with the Synopsys Sentaurus TCAD to develop a guard ring structure that minimizes the electric field throughout the periphery of an n-on-p silicon particle detector. The behavior of the breakdown voltage has been studied as the function of the radiation fluence, the field plate length, and the oxide thickness.
Preliminary results of the performance...

Short strip CNM double-sided 3D sensors have been fabricated and irradiated in a 26MeV proton beam. The devices have received a fluence up to 2x10^16 1 MeV neutron equivalent cm-2. The devices have been tested using the Alibava system with a Sr-90 source. Results of the excellent charge collection of the devices after such high fluences are shown.

CNM double-sided 3D pixel detectors have been fabricated and assembled to the Medipix2 and Timepix ASICs. Medipix2 assemblies have been tested with a micron-sized beam at the Diamond light source to understand the response of the detector as a function of hit position. The same devices and Timepix assemblies have also been tested in a telescope at a pion beam at the SRS. Complimentary...
