چکیده

In x-ray imaging detectors, the signal generated in a detector element is proportional to the number of secondary carriers (such as optical photons or electronhole pairs) generated in the x-ray convertor. Furthermore, the location and statistics of secondary carriers are directly related to the absorbed x-ray energy. Even under monochromatic exposure conditions, there will be a distribution of absorbed energies due to the statistical nature of x-ray interactions.

The safety of a landmine detection system using graphite and polyethylene moderator

Background: Several landmine detection methods, based on nuclear techniques, have been suggested up to now. Neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are the nuclear methods used for landmine detection. In this paper an optimized (safe and effective) moderating structure using an 241Am-Be neutron source for detecting landmines has been invest...

Torque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive

Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...
