For the upgrade of the silicon strip tracker of the ATLAS experiment a detailed study was conducted on silicon strip mini sensors. About 20.000 silicon strip detector modules are foreseen to be built for the upgrade of the inner tracker in 2023. Various tasks in prototyping are currently ongoing. For the test of possible sensors a large number of n-in-p mini strip sensors from Hamamatsu...

N-in-p planar pixel sensors with an active thickness of 200 μm produced at CiS,
and 100-200 μm thin active/slim edge sensor devices, produced at VTT in Finland have been interconnected to ATLAS FE-I3 and
FE-I4 read-out chips and irradiated in Ljubljana, Los Alamos and KIT up to a fluence of 1.4×10^{16} n_{eq}/cm^2.
Charge collection properties and tracking efficiencies are studied to...

Several FE-I3 sized n$^+$-in-n single chip sensors have been irradiated to fluences up to $2 \cdot 10^{16} n_{eq}/cm^2$ which may possibly be reached in the inner ATLAS pixel layers in HL-LHC. To determine the scaling behaviour, the leakage current was measured depending on the voltage or on the temperature for individual sensors.
In addition to these measurements an FE-I3 n$^+$-in-n...

Dedicated RD50 charge multiplication sensors were annealed at room temperature and charge collection measurements were performed after several annealing steps. The multiplication sensors feature different structures specially designed to take advantage of multiplication after heavy irradiation. These devices were produced by Micron Semiconductor Ltd and irradiated with neutrons to fluences of...

The CMS collaboration is planning to upgrade the forward calorimeters as these will not be sufficiently performant with the expected HL-LHC (High Luminosity LHC) conditions. One of the proposed calorimeter options is the High Granularity Calorimeter (HGC). It is realized as a sampling calorimeter with layers of silicon detectors that feature very high longitudinal and lateral granularities and...

After high hadron radiation fluences, the traditional DC coupling of pixel sensors to readout electronics can lead to noise and signal distortion problems, due to the significant current flowing from the sensor through the electronics. AC coupling can offer a more favorable way for feeding the signal to the pre-amplifier, provided that the coupling strength yields a good signal to noise ratio....

In this talk, we will present some technological capabilities that could be of interest for the RD50 community. In this sense, the first results from new PiN diodes integrated on 6-inch N-silicon wafers will be shown. To perform this 6-inch technological process we have upgraded the standard CNM 4-inch process to the new wafer size. Additionally, we will describe the works performed to...

At this time, the CiS research institute is engaged in developments of radiation detector technologies on several different fields. Current projects are dealing e.g. with defect engineering, active edge sensors, large area thinned sensors and sensor-chip packaging technologies.
For large area sensors, the need for smaller thicknesses can be approached by etching cavities to the sensors...
