Photoluminescence (PL) and infrared absorption (IRA) techniques have been applied to study defect centers formed in MCz and FZ by high-fluence neutron irradiation. The MCz-Si and FZ-Si samples prepared by the WODEAN group were irradiated with neutron fluences ranging from 1x10^14 to 3x10^16 cm^-2. The studies were performed in a temperature range of 13 K–100 K using both the as-irradiated...

This work deals with the bistable congurations of the E4/E5-defect levels, which are known to be the important current generator after neutrons and charged hadrons irradiation. We studied 300 um thick n-type diodes made from MCz and FZ-silicon after irradiation with reactor neutrons. Capacitance-Deep Level Transient Spectroscopy (C-DLTS) as well as Capacitance- Voltage and Current-Voltage...

The TCAD Synopsis program was used for: 1) investigation of electric field distribution in Si crystal containing different types and concentration of clusters; 2) analysis of dynamics of electric field around the cluster during and after excitation by a short light pulse. An aim of presentation is an attraction of proposals to model the behavior of semiconductor in other situations.

The radiation damage effects on p- and n-type Float Zone (FZ) and Magnetic Czochralski (MCz) Silicon diodes were characterized by studying the capacitance and depletion voltage. The diodes were exposed to 800 MeV protons
to fluences up to $1.5x10^{15}$ p/cm^2. The diodes were then annealed at 60 °C and measured at various intervals up to 1,000 minutes. The intent of this study is to...

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...

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...

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...
