In this article we aim to investigate the performance of strip detectors as spectroscopes by measuring typical sources of ionizing particles, such as photons or alpha-particles, having a well-defined energy. To this end a 128-strip low noise FPGA-based readout system was fabricated alongside a corresponding dedicated software tool and connected to a Si strip sensor.
In addition, adequate...

Silicon radiation sensors typically have an inactive volume at the device periphery necessary to accommodate multiple guard-rings and current terminating structures necessary to deliver increased breakdown voltage and stability and to shield the active area from the defects induced by the dicing procedure.
The extension of the dead region can be as wide as a few mm, depending on the...

Aim of the presented work is investigation of the wooden paintings (and medieval sculptures decorations) which is based on so-called polychromy. Polychromy consists of several layers in a variety of colors and elemental composition. It is also common that such artifacts have been renovated several times. Therefore, it is highly desirable to investigate the current status of existing...

The proposed 50 kton magnetized Iron Calorimeter (ICAL) detector at India-based Neutrino Observatory (INO) aims to investigate atmospheric neutrino oscillations. The ICAL will employ about 29000 glass Resistive Plate Chambers (RPCs) as the active detector elements and requires millions of electronic channels to be read out. Therefore, a multi-channel readout application specific integrated...

9. “Low Electronic Noise” Detector Technology in Computed Tomography

Dr aziz ikhlef (FMI Medical Systems)

general

Oral

Image noise in computed tomography, is mainly caused by the statistical noise, system noise reconstruction algorithm filters. Since last few years, low dose x-ray imaging became more and more desired and looked as a technical differentiating technology among CT manufacturers. In order to achieve this goal, several technologies and techniques are being investigated, including both hardware...
