During the shutdown of CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between existing Pixel detector ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new layer, Insertable B-Layer (IBL), to maintain or improve robustness performance tracking system, given higher instantaneous integrated luminosities realised following shutdown. Because extreme radiation collision rate environment, several radiation-tolerant sensor electronic...
In this paper we report on the timing resolution of first production 50 micro-meter thick Ultra-Fast Silicon Detectors (UFSD) as obtained in a beam test with pions 180 GeV/c momentum. UFSD are based Low-Gain Avalanche (LGAD) design, employing n-on-p silicon sensors internal charge multiplication due to presence thin, low-resistivity diffusion layer below junction. The used belongs thin (50 μm) sensors, an pad area 1.4 mm2. gain was measured vary between 5 and 70 depending bias voltage....
A Transient Current Technique (TCT) utilizing an IR laser with 100 ps pulse width and beam diameter of FWHM = 8 μm was used to evaluate non-irradiated irradiated p-type silicon micro-strip detectors. The parallel the surface perpendicular strips (Edge-TCT) so that electron hole pairs were created at known depth in detector. Induced current pulses measured one strips. shapes analyzed a new way, which does not require knowledge effective trapping times, determine drift velocity, charge...
The ATLAS collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing and vacuum pipe of Large Hadron Collider. extreme operating conditions at this location have necessitated development radiation hard sensor technologies front-end readout chip, called FE-I4. Planar sensors 3D been investigated to equip layer, prototype modules using FE-I4A fabricated characterized 120 GeV pions CERN SPS 4 positrons DESY, before after module...
Novel silicon detectors with charge gain were designed (Low Gain Avalanche Detectors - LGAD) to be used in particle physics experiments, medical and timing applications. They are based on a n++-p+-p structure where appropriate doping of multiplication layer (p^+) is needed achieve high fields impact ionization. Several wafers processed different junction parameters resulting gains up 16 at voltages. In order study radiation hardness LGAD, which one key requirements for future energy several...
Four different combinations of 4496Ru and 4096Zr nuclei, both as projectile target, were investigated at the same bombarding energy 400AMeV using a 4π detector. The degree isospin mixing between target nucleons is mapped across large portion phase space two isospin-tracer observables, number measured protons tritium to 3He yield ratio. experimental results show that global equilibrium not reached even in most central collisions. Quantitative measures stopping are extracted from data. They...
Using the FOPI facility at GSI Darmstadt complete data of Au on collisions 150A MeV were collected for charged products (Z=1–15) laboratory angles 1°≤Θlab≤30°. Central selected by applying various criteria.

Edge-TCT method was used to extract velocity profiles in heavily irradiated silicon micro-strip detectors. Detectors were up 1016 c -2 with reactor neutrons, 200 MeV pions and a combination of both. A simple electric field model assuming two space charge regions at each side the detector neutral bulk in-between found describe profile. It observed that after heavy irradiation sizeable is present entire volume. For pion-irradiated detectors strikingly different obtained attributed large oxygen...
