Abstract Advances in data analysis and model prediction offer new potential for enhancing radiation measurement technologies, particularly detector characterization real-time signal analysis. A key challenge is creating realistic models that accurately describe the complex physical processes of photon-matter interaction, formation including material characteristics, to enhance design optimization physics understanding. This research study introduces development an Advanced Theoretical...
Abstract This feasibility study explores the possibility of using 3D CZT drift strip detectors developed by DTU Space in a small Compton camera payload, with primary objective technology demonstration. We have defined scalable mass model for comprising eight surrounded CsI scintillator active shielding. The payload's angular resolution, effective area, and efficiency are evaluated through simulations far-field monochromatic point sources. instrument's sensitivity is assessed low Earth orbit...
At DTU Space, a high-resolution 3D CZT drift strip detector has been developed and number of prototype detectors were fabricated, allowing for sub-mm position resolution at high energies (>100 keV), as well energy resolution. For spectral spatial performance, the characterized with fine collimated high-energy (Cs137) monochromatic beam (0.2 mm × 40 mm) using digitizer which pulse shapes bi-polar signals from all electrodes could be analysed. Data analysis consist determination single double...
At DTU Space a 3D CdZnTe (CZT) drift strip detector prototype of size 20mm x 4.7mm has been developed.It demonstrated excellent submillimeter position resolution (< 0.5mm), and energy 1.6%) at 661.6keV using pulse shape signal processing.Signal formation on each the 26 electrode readouts uses bi-polar Charge Sensitive Pre-amplifiers.The output is sampled high speed digitizers; providing us with full shapes generated by interaction in detector.In order to optimize understand performance,...
What do medical imaging and astronomy have in common? Whether it is detecting tumors or observing colliding neutron stars, both fields can benefit from the same sensor technology. When radiation MeVband (0.1-100 MeV) celestial sources, one faces challenges like low flux, limited interaction probability, three energy loss processes, a high background rate. Present MeV-band observatories suffer poor sensitivity, new state-of the-art detector technology will be key contributor to improve...
X-ray mammography is a widely used technique for breast cancer screening. However, the imprecise when it comes to radiographically dense tissue, and therefore supplemental screening technique, such as molecular imaging (MBI), could increase detection rate. Emerging technologies within MBI require excellent detector performance, preferably with submillimeter intrinsic spatial resolution. A collaboration between Kromek DTU Space aims advance developed 3-D CdZnTe (CZT) drift strip technology,...
