Radiation field effects on the spectroscopic properties of seeded plasmas
The presence of an external radiation field can affect the level populations that occur in a high-temperature plasma. The level populations determine, in part, the emissivity of the medium. Hence, processes induced by the radiation field must be included in spectral simulations. In the present paper...

Radiation field effects on the spectroscopic properties of seeded plasmas |
| abstract |
The presence of an external radiation field can affect the level populations that occur in a high-temperature plasma. The level populations determine, in part, the emissivity of the medium. Hence, processes induced by the radiation field must be included in spectral simulations. In the present paper, the effect of black body radiation with temperatures of several hundred eV on mid-Z seeded plasmas, with electron temperature between 100 and 4000 eV, and electron densities between 10^1^9 and 10^2^2 cm^-^3 is studied. Particular attention is focused on line ratios which are commonly used for diagnostics. It is shown that the radiation field can have significant impact on the spectroscopic properties of plasmas under these conditions. A possible electron temperature diagnostic using iron is suggested for moderate radiation temperatures. |

The level populations determine, in part, the emissivity of the medium. Hence, processes induced by the radiation field must be included in spectral simulations. In the present paper, the effect of black body radiation with temperatures of several hundred eV on mid-Z seeded plasmas, with electron temperature between 100 and 4000 eV, and electron densities between 10^1^9 and 10^2^2 cm^-^3 is studied. Particular attention is focused on line ratios which are commonly used for diagnostics. It is shown that the radiation field can have significant impact on the spectroscopic properties of plasmas under these conditions. A possible electron temperature diagnostic using iron is suggested for moderate radiation temperatures.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Abdallah, J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Clark, R.E.H.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Keane, C.J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shepard, T.D.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Suter, L.J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Quantitative Spectroscopy and Radiative Transfer</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">50(1993), 1, Seite 91-101</subfield><subfield code="w">(DE-627)NLEJ177070757</subfield><subfield code="w">(DE-600)1491916-3</subfield><subfield code="x">0022-4073</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:50</subfield><subfield code="g">year:1993</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:91-101</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0022-4073(93)90132-2</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">50</subfield><subfield code="j">1993</subfield><subfield code="e">1</subfield><subfield code="h">91-101</subfield></datafield></record></collection>
