“…The ion is then left in a (usually) doubly-excited state which can decay radiatively, completing the DR process. Extended experimental and theoretical investigations on DR with highly charged ions (HCI) have been carried out in recent years by various groups (e. g. [3][4][5][6][7][8]). Usually, DR is described in an independent-particle model, only taking into account the interaction between the two electrons involved -the initially free one and an active bound one.…”

Dielectronic and higher-order resonant electron recombination processes including a K-shell excitation were systematically measured at high resolution in electron beam ion traps. Storing highly charged Ar, Fe, and Kr ions, the dependence on atomic number Z of the contribution of these processes to the total recombination cross section was studied and compared with theoretical calculations. Large higher-order resonant recombination contributions are found, especially for systems with 10 < Z < 36. In some cases, they even surpass the strength of the dielectronic channel, which was hitherto presumed to be always the dominant one. These findings have consequences for the modeling of high-temperatur plasmas. Features attributed to inter-shell quadruelectronic recombination were also observed. The experimental data obtained for the He-like to O-like isoelectronic sequences compare well with the results of advanced relativistic distorted-wave calculations employing multiconfiguration Dirac-Fock bound state wave functions that include threefold and fourfold excitations.

“…An EBIT is a useful device for studying DR processes of highly charged heavy ions since it has a (quasi-)monoenergetic electron beam whose energy can be easily and rapidly controlled [16,17]. By using the Tokyo-EBIT, we have been studying DR processes through both X-ray observations [18] and ion abundance measurements [19,20].…”

In this paper, we present recent activities at the Tokyo EBIT after giving an overview of the present status of the devices. We have been studying dielectronic recombination processes by means of several techniques. In addition to X-ray observations and charge abundance observations, 2-photon observations have been recently used to study DR processes which emit two photons successively (but practically simultaneously). Recent efforts on spectroscopic work are mainly concentrated on Fe and W ions, which are relevant to astrophysical and fusion plasmas. JINST 5 C08007Several spectrometers that can cover a wide range of wavelength, such as visible, EUV, and Xrays, were used for accumulating useful data for plasma diagnostics applications. HCI-surface collision processes were studied using ions extracted through the beam line, that has recently been modified. Very highly charged ions up to Bi 81+ were used for studying the effect of huge potential energy.KEYWORDS: Low-energy ion storage; Ion sources (positive ions, negative ions, electron cyclotron resonance (ECR), electron beam (EBIS)) -1 -2010 JINST 5 C08007
