Application of a pnCCD for energy-dispersive Lauc diffraction with ultra-hard X-rays
Send, Sebastian; Abboud, Ali; Wiesner, Nadja; Shokr, Mohammad Mahdi; Çonka Yıldız, Tuba; Klaus, Manuela; Hartmann, Robert (Int Union Crystallography, 2015)In this work the spectroscopic performance of a pnCCD detector in the ultra-hard energy range between 40 and 140 keV is tested by means of an energy-dispersive Laue diffraction experiment on a GaAs crystal. About 100 Bragg ... -
Applications of a pnCCD detector coupled to columnar structure CsI(Tl) scintillator system in ultra high energy X-ray Laue diffraction
Shokr, Mohammad Mahdi; Schlosser, Dieter Michael; Abboud, Ali; Algashi, Alaa; Tosson, Amir; Çonka Yıldız, Tuba; Pietsch, Ullrich (Iop Publishing Ltd, 2017)Most charge coupled devices (CCDs) are made of silicon (Si) with typical active layer thicknesses of several microns. In case of a pnCCD detector the sensitive Si thickness is 450 mu m. However, for silicon based detectors ... -
Design criteria for a high energy Compton Camera and possible application to targeted cancer therapy
Çonka Yıldız, Tuba; Nurdan, Kıvanç; Brill, Aaron B.; Walenta, A. H. (Iop Publishing Ltd, 2015)The proposed research focuses on the design criteria for a Compton Camera with high spatial resolution and sensitivity, operating at high gamma energies and its possible application for molecular imaging. This application ... -
Direct and indirect signal detection of 122 keV photons with a novel detector combining a pnCCD and a CsI(T1) scintillator
Schlosser, Dieter Michael; Huth, M.; Hartmann, Robert; Abboud, Ali; Send, Sebastian; Çonka Yıldız, Tuba; Strüeder, Lothar (Elsevier, 2016)By combining a low noise fully depleted pnCCD detector with a CsI(TI) scintillator, an energy-dispersive area detector can be realized with a high quantum efficiency (QE) in the range from below 1 keV to above 100 keV. In ... -
GamSim - a windows-based simulation tool for Gamma-Ray detector development
Walenta, Albert H.; Brill, A. Bertrand; Çonka Yıldız, Tuba; Fleck, Ivor; Furenlid, Lars R.; Peterson, T. E. (Ieee, 2016)After the introduction of radiation simulation tools such as Geant4 or EGS in nuclear and high energy physics, the use in applied fields like nuclear medicine becomes increasingly important and a number of extensions have ... -
A new spectroscopic imager for X-rays from 0.5 keV to 150 keV combining a pnCCD and a columnar CsI(Tl) scintillator
Schlosser, Dieter Michael; Hartmann, Robert; Kalok, D.; Bechteler, A.; Abboud, Ali; Shokr, Mohammad Mahdi; Strüeder, Lothar; Çonka Yıldız, Tuba (Iop Publishing Ltd, 2017)By combining a low noise fully depleted pnCCD detector with a columnar CsI(Tl) scintillator an energy dispersive spatial resolving detector can be realized with a high quantum efficiency in the range from below 0.5 keV to ... -
Single-shot full strain tensor determination with microbeam X-ray Laue diffraction and a two-imensional energy-dispersive detector
Abboud, Ali; Kirchlechner, C.; Keckes, J.; Çonka Yıldız, Tuba; Send, S.; Micha, J. S.; Pietsch, U. (Int Union Crystallography, 2017)The full strain and stress tensor determination in a triaxially stressed single crystal using X-ray diffraction requires a series of lattice spacing measurements at different crystal orientations. This can be achieved using ...
