Secure iter operation

Secure ITER operation

  • EFDA: ITER Physics

  • PWI: several areas, 8ppy

    More specific to Microanalytical Center, Jozef Stefan Institute:

    1 We are very much interested in continuing the coordinated studies of samples from tokamaks or other relevant experiments by ion beam analytical methods. Our experimental facility is continuously upgraded and we are providing ERDA and NRA techniques with macro (1mm) and micro (< 5 micrometer) beam besides other IBA methods.Restrictions.

    2 A substantial construction project of incorporating an ultrahigh brightness multicusp H- ion source into our 2MV Tandem accelerator is under way. This will provide high brightness high energy H+ beam, high energy H0 and high brightness low energy H- beam for analytical purposes, surface reaction and material damage studies.

    3Interest in in-depth understanding of surface reactions which we can continue to study by in situ IBA methods ERDA and RBS. Even we have restricted our previous studies (and interests) to the interaction of neutral atomic hydrogen (H and D) with surfaces we can now extend similar studies to incident ions as we recently purchased a micro-wave sputter ion gun.

Secure iter operation1

Secure ITER operation

  • EFDA: ITER Physics

  • PWI: several areas (deposits removal)

    - Collaborations (CIEMAT, institutes outside of fusion programme)

  • The work has been focused on the problem of hydro-carbon deposits. On one hand, we have been working on removing a-C:H deposits by means of neutral oxygen atoms (development of suitable reactors, experiments with mixed a-C/W:H deposits), while on the other hand we have been working on preventing the formation of a-C:H deposits with the scavenger technique.

  • Both branches of research have yielded satisfactory results, so work in the near future will be aimed at further developing the researched fuel removal techniques.

  • As new materials – candidates for PFCs – are developed (such as SiC/SiC), we intend to focus our research on their interaction with neutral H atoms, as well as verification of their compatibility with existent cleaning methods.

Secure iter operation2

Secure ITER operation

  • EFDA: ITER Physics

  • PWI: several areas (fuel retention, fuel permeation)

  • Deuterium retention in Be-W mixed layers (ITER)

  • Tritium barriers for DEMO

  • - Selection of tritium permeation barrier materials should be revised since the last systematic reviews several new materials were synthesized and available data should be revised.

  • - Barrier properties should be investigated regarding capability to be deposited over large areas.

  • - They should be investigated by regular permeation tests at temperatures expected in DEMO.

  • - Finally, the best candidate materials should be tested in radiation environments.

Prepare generation iter

Prepare “Generation ITER”

  • 2005 – 2011: first generation PhDs (6) with fusion theses, post docs (JSI) at JET, at universities in UK, Germany, IPP

  • 2012 – 2020: FUSENET, similar fusion oriented courses, summer schools

    - only special subjects (general) at our unis and/or institute

    - expectations: 15 – 20 during the whole decade
