The radioactive isotope beam (RIB) of 25Na at 5MeV/u energy in maximum 3x107 pps intensity was fired on a deuterated polyethylene (CD2) to investigate mainly (d,p gamma) reaction. However, there were other reaction possibilities, which arisen from the same collision, be eliminated wisely. As particle detector and gamma-ray detector, highly selective double-sided silicon strip detectors (DSSSD) ...

The Large Area Telescope (LAT) on board the Gamma-ray Large-Area Space Telescope (GLAST) is a pair-conversion gamma-ray detector designed to explore the gamma-ray universe in the 20 MeV– 300 GeV energy band. The Tracker subsystem of the LAT will perform tracking of electron and positrons to determine the origin of the gamma-ray. The design and performance of the GLAST LAT Tracker are described ...

This work describes preliminary test studies with a dual-headed SPECT system that utilizes a new generation of silicon double-sided strip detectors (DSSDs) (Figure 1) with a 1-mm bulk thickness and larger active area (60 × 60 mm) as compared to standard gamma-ray silicon detectors. Furthermore, major improvements in the ASIC design make this detector very suitable for low-energy imaging of smal...

Milagrito, a large, covered water-Cherenkov detector, was the world's "rst air-shower-particle detector sensitive to cosmic gamma rays below 1 TeV. It served as a prototype for the Milagro detector and operated from February 1997 to May 1998. This paper gives a description of Milagrito, a summary of the operating experience, and early results that demonstrate the capabilities of this technique....

Abstract Gamma-ray imaging is a technique for visualizing the spatial distribution of radioactive materials. has recently been applied to research on environmental restoration and decommissioning Fukushima Daiichi Nuclear Power Station (FDNPS). In this paper, we present an elemental technology study gamma-ray imager using small-angle scattering (GISAS), which intended application at FDNPS site....

In-beam gamma-ray and electron spectroscopy have been widely used as tools to study the broad variety of phenomena in nuclear structure. The SPEDE spectrometer is a new device to be used in conjunction with the MINIBALL germanium detector array to enable the detection of internal conversion electrons in coincidence with gamma rays from de-exciting nuclei in radioactive ion beam experiments at t...

Quantum dots (QDs) have attracted tremendous interest over the last few years for a large variety of applications ranging from optoelectronic through photocatalytic to biomedical, including applications as nanophosphors in light emitting diodes LEDs [1]. QDs have been suggested as scintillators for detection of alpha particles and gamma-rays [1-4]. Quantum dots offer an improvement on scintilla...
