Following the achievements in X-ray imaging several new imaging modalities have been demonstrated recently in thermal and cold neutron radiography. In addition to conventional radiography and tomography based on neutron absorption contrast both propagation and grating-based diffraction contrast as well as phase contrast imaging has been demonstrated with neutrons providing unique...

The SemiConductor Tracker (SCT), comprising of silicon micro-strip detectors is one of the key precision tracking devices in the ATLAS Inner Detector. ATLAS is one of the experiments at CERN LHC.
The completed SCT is in very good shapes with 99.3% of the SCT’s 4088 modules (a total of 6.3 million strips) are operational. The noise occupancy and hit efficiency exceed the design...

Radon gas, 222Rn, is a problem in many buildings. The radon gas is not harmful in itself, but the decay chain contains charged elements as 218Po, and 214Po ions which have a tendency to stick to the lungs. Alpha particles from the decay of these ions cause damages to the lungs and increase the risk of lung cancer. Exposure to radon is estimated to cause between 3-14% of all lung cancer cases,...

The ATLAS muon spectrometer consists of a system of precision tracking and trigger chambers embedded in a 2T magnetic field generated by three large air‐core superconducting toroids. The precision Monitored Drift Tube (MDT) chambers measure the track sagitta up to a pseudo‐rapidity of 2.7 with a 50 μm uncertainty yielding a design muon transverse momentum resolution of 10% at 1 TeV. Muon...

In a high-resolution (micrometer spatial resolution) X-ray imaging detector [1], the Single Crystal Film (SCF) is the first element of the detection chain. Its role is crucial as its efficiency and thickness directly impacts the Detective Quantum Efficiency (DQE) of the detection system. The ideal SCF should possess high absorption efficiency, high light output, low afterglow, optical match...

Neutrinoless double beta decay (0nuBetaBeta) is a problem of great interest in particle physics (e.g.[1], [2]). It is the best process to study the nature of the neutrino (Dirac or Majorana particle) and could clarify its mass scale. This year the NEMO collaboration [3] has finished main R&D of the SuperNEMO detector design to improve the sensitivity to T1/2(0nu) to the level of ~10^26 years...

Over the last decades the traditional photographic films used in radiology have been replaced by the digital X-ray imaging sensors. The main advantages of these systems are their detection efficiency of the image acquisition and the ability to directly digitally transfer and enhance obtained images. In this paper we characterize and evaluate the X-ray imaging performance of a YAG single...

The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at the Large Hadron Collider at CERN, providing high-resolution measurements of charged particle tracks in the high radiation environment close to the collision region. This capability is vital for the identification and measurement of proper decay times of long-lived particles such as b-hadrons, and thus vital for the...

There is an ever growing need for highly effective electron detectors with high responsivity. One of the parameters that has been shown to have a negative influence on the responsivity of a radiation detector is the surface recombination velocities of minority carriers at the Si-SiO2 interface. With the n+p detector discovered to possess better responsivity than a p+n detector at any given...

The paper is devoted to design, numerical modeling, fabrication and evaluation of a detector with the new electrodes topology: standard sandwich-like two electrode detector is complemented by an additional electrode surrounding the small circular anode Schottky contact. It is shown that the detection efficiency of such detector with connected bottom and surface electrode increases 2-4 times...
