Miniature p-type strip detectors were irradiated with reactor neutrons to fluences in the range from 2e14 neq/cm2 to 5e15 neq/cm2. Collected charge was measured with signals caused by fast electrons from Sr90 source and read out by SCT128A chip. Collected charge and leakage current was measured up to high bias voltages (1400 V) at which signs of charge multiplication can be observed....

HPK FZ p-on-n ministrip detectors, of the type currently used in several LHC experiments, have been irradiated both with protons and neutrons to equivalent fluences of 1e15 n/cm^2. The detectors have then been characterized with beta CCE measurements based on the ALIBAVA system throughout several annealing steps, to assess the effect on the performances of the detectors of hypothetical long...

With the fully operational ALiBaVa setup at Karlsruhe an annealing study of a standard CMS mini sensor (FZ, n-type) was performed. The chosen fluence of 7.5e14 Neq/cm2 lies well above expectation for strip sensors after 300fb-1 at LHC and allows exploring the performance at even higher fluence, e.g. due to higher integrated luminosity before replacement of the strip Tracker or as material for...

HPK p-type sensor was irradiated in steps with reactor neutrons up to the fluence of 1e16 cm-2. After each step several Edge-TCT measurements were performed during initial stage of annealing. Charge collection properties, drift velocity profiles were investigated as a function of annealing, fluence and bias voltage.

Silicon strip detector modules that are used in tracker systems of high energy physics experiments consists of readout hybrid board, the sensor itself and pitch adapter (PA) in between hybrid and sensor. Modern strip detectors are almost exclusively AC-coupled because of high leakage current due to the harsh radiation environment. The AC-coupling requires resistive isolation of implanted...

The project aims to fabricate and fully characterize p-type strip detectors with trench electrodes to enhance the charge multiplication effect in the irradiated devices.

We checked the effectiveness of PTP structures against large deposits of ionization in the detector bulk using an IR laser, and compared it with the results of commonly used DC i-V measurements.

A novel microstrip sensor with polysilicon electrodes manufactured at CNM-IMB is introduced. The slightly resistive electrodes allows the determination of the particle's hit position along the microstrip direction using a charge-division-based readout. Preliminary results from laser, radioactive source and test beam characterization are given.

Silicon n-in-p pixel detectors from the latest CiS production are detectors similar to ones from the latest ATLAS pixel production.
First measurements of irradiated CiS n-in-p single chip assemblies (SCA) connected to the current ATLAS front end chip FE-I3 were performed during the last weeks. Characterization results will be presented from devices irradiated with protons and neutrons up to...

ATLAS SingleChip-Assemblies based on the FE-I3 readout chip have been irradiated with reactor neutrons in Ljubljana to fluences up to 2E16 neq/cm^2. First measurements obtained with a Sr-90 source in the lab will be presented. The collected charge will also be compared to preliminary testbeam results.

A report on the development of a high resolution particle tracking telescope based on the Timepix pixel detector. Using the different modes of operation available in Timepix a Telescope system has been developed that can provide a spatial resolution of under 2 microns and a timing resolution to the order of a nanosecond. This track time tagging ability has been used to incorporate an...
