88. (withdrawn) Update on electron-H2 and -D2 cross sections

Dr Vincenzo Laporta (Istituto per la Scienza e Tecnologia dei Plasmi, CNR, Italy)

29/11/2023, 13:30

Oral

In this talk will be presented our last results on electron-H${}_2$ and -D${}_2$ collisions. We will focus in particular on the vibrational-excitation, dissociative-attachment, dissociative-recombination and dissociative-excitation processes rotationally and vibrationally resolved.

89. Atomic data needs for studying of W sputtering in high density divertor plasmas

Oral

W generation and transport study represents one of the hottest topics for next generation tokamaks with full metal plasma-facing components [1-4]. The existing W sputtering models are based on low density plasma sheath approximation [5-7], which might be not applicable for high density divertor plasmas expected in future machines, e.g. like ITER and DEMO.

In the given presentation we...

75. Electron collisions with molecular hydrogen and its isotopologues

Oral

Electron-molecule cross sections resolved in the rovibrational levels of the target are required for determining the properties and dynamics of many low-temperature plasmas. We have applied the Molecular Convergent Close-Coupling (MCCC) method to produce a comprehensive set of vibrationally-resolved cross sections for electron collisions with molecular hydrogen and its isotopologues comprised...

74. Inclusion of opacity in collisional-radiative models of hydrogen-like He and D to explain discrepancies with line intensity measurements in the JET tokamak

Kerry Lawson (ccfe)

Oral

An understanding of the description of the discharge fuel, either D or He, is essential in order to model processes in the plasma edge and divertor, these processes including transport simulations of the plasma exhaust and the determination of plasma-facing surface erosion. The emission from the fuel species is described by collisional-radiative models. However, discrepancies have been found...

68. Energy levels, transition rates, lifetimes of transmutation of tungsten atoms He-like-(Hf, Ta, Re and Os) deduced from relativistic multiconfiguration Dirac–Hartree–Fock and many body perturbation theory calculations

Prof. Haikel JELASSI (National Centre for Nuclear Sciences and Technologies)

Poster

The present study has determined excitation energy of the 127 states of the transmutation of tungsten atoms He-like-(Hf, Ta, Re and Os). In this work, we use the ab initio MCDHF and MBPT methods implemented in GRASP2018 and FAC codes, respectively. We extend the calculation for n = 8 to improve the precision of the atomic data used in line identification, plasma modeling and diagnostics of...
