Walther Bothe and Bruno Rossi: the birth and development of coincidence methods in cosmic-ray physics
Walther Bothe and Bruno Rossi cosmic-ray physics
2011/8/31
In 1924 Walther Bothe and Hans Geiger applied a coincidence method to the study of Compton scattering with Geiger needle counters. Their experiment con rmed the existence of radiation quanta and estab...
Fourier transform based iterative method for x-ray differential phase-contrast computed tomography
X-ray phase-contrast tomography, x-ray refractive index, iterative reconstruction,interior tomography
2011/9/6
Biological soft tissues encountered in clinical and pre-clinical imaging mainly consist of light element atoms, and their composition is nearly uniform with little density variation. Thus,x-ray attenu...

Trackong detectors silicon detectors LHC
2010/3/15
The calibration and performance of the Silicon Drift Detector of the ALICE experiment during the 2008 cosmic ray run will be presented. In particular the procedures to monitor the running parameters (...
The Origin of X-Ray Emission Lines From SS Cgy
Cataclysmic Variables emission lines SS Cyg dwarf novas
2010/4/9
SS Cyg is a dwarf nova binary star that undergoes frequent large amplitude outburst within a period of 40 days. SS Cyg was observed with the Chandra x-ray telescope in quiescence on 2000 August 24, an...
Development and Applications of Three-dimensional Gamma Ray Tomography System Using Ray Casting Volume Rendering Techniques
Three-dimensional Gamma Ray Tomography System Ray Casting Volume Rendering Techniques
2010/10/15
Computed Tomography (CT) has made possible visualization of physical structures in the interior of an object in their real relative spatial position and orientation. Another important contribution of ...
New accelerator facilities for radioactive-ion beams and high-intensity stable beams will start operation in a few years. Although these beams will provide interesting opportunities for exploring unkn...
Analysis of Concrete Material through Gamma Ray Computerized Tomography
Concrete Material Gamma Ray Computerized Tomography
2010/10/26
Computerized Tomography (CT) refers to the cross sectional imaging of an object from both transmission or reflection data collected by illuminating the object from many different directions. The most ...
In this work several structural and chemical properties of self-assembled InAs islands grown on GaAs(001) are studied using surface x-ray scattering with synchrotron radiation. The technique of x-ray ...
This paper gives a brief overview of the technical progress that can be achieved with the newly available segmented HPGe detectors. Gamma-ray tracking detectors are a new generation of HPGe detectors ...
