Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
Abstract JET, the world’s largest operating tokamak with unique Be/W wall and tritium handling capability, completed a Deuterium-Tritium (D-T) campaign in 2021 (Maggi et al 29th Fusion Energy Conf. ) following decade of preparatory experiments, dedicated enhancements, technical rehearsals training (Horton 2016 Eng. Des. 109–111 925). Operation raises significant technical, safety scientific challenges not encountered standard protium or deuterium operation. This contribution describes...
We describe the occurrence of electromagnetically induced transparency (EIT), absorption (EIA), and Fano resonance due to time-controlled discontinuities in refractive index a medium, which leads formation double-cavity system inside temporal photonic crystal. The resonances partly resemble optical arising conventional microcavities, since amplified EIA displays distinct spectral characteristics. Although an EIT does not occur, strongly affects behavior as well. Besides modifying via...
We present elemental compositions of different stones found in the locality Mirpur region Azad Jammu and Kashmir using laser-induced breakdown spectroscopy (LIBS). The optical emission spectra have been recorded an neodymium-doped yttrium aluminum garnet laser (1064 nm) conjunction with LIBS-2000 setup to categorize existence various elements studied effects irradiance on intensities, widths, shifts spectral lines. Gray show multiple elements: Ca, Fe, Mg, Sr, Na, Li, whereas Half-White...
Abstract Laser-induced breakdown spectroscopy has been exploited to investigate the laser-produced lead plasma with and without external magnetic field. Plasma on surface was generated by focusing a beam of Nd:YAG laser (532 nm). An field applied across plasma; its value varied from 0.3 0.7 T time-integrated spectra were captured at different time delays. Maximum enhancement in neutral ionic line intensities have observed 130 mJ energy. The Pb 368.34 nm reveals an factor nearly 1.3, 1.6, 2.3...
The problem of electromagnetic scattering a plane wave from topological insulator (TI) cylinder buried beneath flat interface is undertaken with the method analysis based on spectral representation fields. Saddle point employed to evaluate involved integrals serving as basis functions in representations scattered-reflected and scattered-transmitted distinctions between pattern for time reversal symmetry TI that broken are pronounced. Results validated through comparison previously available results.
A general theoretical formulation is done to calculate the field scattered by perfect electromagnetic conductor (PEMC) cylinder coated with anisotropic plasma material. It buried below a slightly rough surface. Spectral plane wave representation of fields and small perturbation method are used multiple reflections between To validate present formulation, from PEMC double negative (DNG) material obtained formulation. Scattering pattern non PEC/PEMC or isotropic can also be proper selection...
