چکیده
The Joint European Torus (JET) gamma-ray camera has been recently upgraded with the installation of new detectors, based on LaBr3(Ce) scintillation crystals, which add spectroscopic capability to existing system allowing measurements good energy resolution (5% at 0.622 MeV), a dynamic range from hundreds keV up about 30 MeV, and high counting rate capabilities MCps. First during C38 campaign JET have successfully carried out, in particular, D–3He plasmas three-ion ion cyclotron resonance heating experiments, where detection 16.4 MeV ?-rays D + 3He ? ? 5Li reactions upgrade allowed determining spatial profile alpha particles born fusion reactions.

First gamma-ray measurements of fusion alpha particles in JET trace tritium experiments.
Gamma-ray spectra from nuclear reactions between fusion-born alpha (alpha) particles and Be impurities were measured for the first time in deuterium-tritium plasmas in the Joint European Torus. The time dependence of the measured spectra allowed the determination of the density evolution of fast alpha particles. Correlation between the decay time of the gamma-ray emission and the plasma paramet...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولThe supernova-gamma-ray burst-jet connection.
The observed association between supernovae and gamma-ray bursts represents a cornerstone in our understanding of the nature of gamma-ray bursts. The collapsar model provides a theoretical framework for this connection. A key element is the launch of a bipolar jet (seen as a gamma-ray burst). The resulting hot cocoon disrupts the star, whereas the (56)Ni produced gives rise to radioactive heati...
متن کاملTesting Gamma - Ray Burst Jet Structure with the Distribution of Gamma - Ray Energy Release
We present a general method for testing gamma-ray burst (GRB) jet structure and carry out a comprehensive analysis about the prevalent jet structure models. According to the jet angular energy distribution, we can not only derive the expected distribution of the GRB isotropic-equivalent energy release for any possible jet structure, but also obtain a two-dimensional distribution including redsh...
