The recent experimental observations of triple tracks in solid-state nuclear track detectors, CR-39, during Pd/D co-deposition experiments indicate that the triple tracks are due to∼14 MeV neutrons, which appear to originate from “hot” fusion reaction D(t,n)He. Nuclear theory interpretation of the origin of ∼14 MeV neutrons is presented in terms of a sub-threshold resonance reaction involving (...

For the central tracking chamber of the JADE detector [l] at the e+estorage ring PETRA a new type of drift chamber, the so-called jet chamber, has been developed [Z-4]. This chamber is capable of recording events of high local track density (jets) with good space and double track resolution and with the possibility of particle identification within a solid angle close to ~I'I sterad. The concep...

background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

The purpose of this article is to provide a brief overview of the background, basic principles, technological evolution, clinical capabilities, and future directions for functional tumor imaging as PET evolves from the conventional photomultiplier tube-based platform into a fully digital detector acquisition platform. The recent introduction of solid-state digital photon counting PET detector i...

This paper presents an alternative to conventional gamma camera. The proposed system is based on the combination of a new detection material – CZT and a new acquisition geometry – 1D detector with slat collimator. The slat collimator offers a better compromise to the usual sensitivity-resolution tradeoff. Solid-state detection offers significantly improved energy resolution. The combination of ...
