Purpose HPGe detectors can be used for both dark matter search and neutrinoless double beta decay experiments.However,signal amplitudes of these two experiments are quite different.This paper presents the development ...
Using a scanning electron microscope (SEM) in the back-scattered electron (BSE) mode the composition of multi-element specimens may be determined based on the strong dependence of emission coefficient η on the averag...

This paper describes a novel,semiautomated design methodology based on a genetic algorithm(GA)using freeform geometries for microelectromechanical systems(MEMS)devices.The proposed method can design MEMS devices compr...
The service provided by the GC(Gamma Cameras)in the Nuclear Medicine departments fails because of their breakdown,generally due to the associated electronics and not to the physical detection components.For this reaso...
