JOURNEES SCIENTIFIQUES DE L’EDOM 2012


Mohammad m alshorman ismo cnrs univ paris sud 11 directed by jean marc bizau

  • Outline

  • Interests.

  • Merged-beam experiment: N+

  • Simulation:

    • simulation of ions trajectories in MAIA setup to improve the intensity of the ion beam and overlap between the photon and ion.

  • Preliminary results of N2+.

  • Future Work.

    Interests

    • Fundamental:

      Nice tool to study electron correlation effects.

    • Plasmas diagnostics and modeling:

      Spectroscopic information: ionization thresholds, excitation energies

       Interpretation of the observations of the X-ray observatories (Chandra, XMM Newton).

    • Dynamical information: Absolute PI cross sections, oscillator strengths.

    • Theoretical interest:

    • The majority of this experimental data has been benchmarked with state-of-the-art theoretical methods as R-matrix and MCDF (Multi-Configurational Dirac–Fork calculations) calculations.

    Merged-Beam Set-Up (MAIA) Endstation

    on SOLEIL Undulator PLEIADESBeamline

    ECRIS: electron cyclotron ion source, E: einzel lens, St: set of horizontal and vertical steerers, S: collimating slits, FC: Faraday cup, ED: electrostatic deflector, IR: interaction region, EQ: electrostatic quadrupole, SR: synchrotron radiation, PD: photodiode.

    Results

    The distribution for 1s22s22p23P,1D,1S and 1s22s2p35So are

    0.54, 0.11, 0.03, 0.32 respectively.

    Results


    Mohammad m alshorman ismo cnrs univ paris sud 11 directed by jean marc bizau

    Future work.

    • We will continue with k-shell photoionization for N2+ and N3+ soon, at the end of this month.

    • We will extend our work with isonuclear sequence for O+ions.

    • -We will try molecular Nitrogen with a new modified trap.

    • I will continue the simulation until the interaction region.
