A multiple shooting method was used to solve the nonlinear coupled differential equation system, with ohmic heating and bremsstrahlung radiation as sources and sinks, respectively. Data from a single ZaP pulse are reported including profiles of magnetic field and temperature and their evolution. Profiles are dominated by high thermal conductivity near the axis which quickly decreases with radius. This is due to the plasma being weakly magnetized near the axis which increases thermal conductivity and flattens the temperature profile, but strongly magnetized near the characteristic radius, significantly reducing thermal conductivity and resulting in a large temperature gradient. The equilibrium evolution indicates that plasmas in ZaP heat and compress with increasing current as a result of magnetic compression during the quiescent period. | ||

Profiles are dominated by high thermal conductivity near the axis which quickly decreases with radius. This is due to the plasma being weakly magnetized near the axis which increases thermal conductivity and flattens the temperature profile, but strongly magnetized near the characteristic radius, significantly reducing thermal conductivity and resulting in a large temperature gradient. The equilibrium evolution indicates that plasmas in ZaP heat and compress with increasing current as a result of magnetic compression during the quiescent period.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">plasma heating</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Measurement by laser beam</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Laser beams</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Probes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Z-pinch</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Equilibrium evolution</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Density measurement</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">pinch oscillation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Conductors</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Plasmas</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Interferometry</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Magnetic fields</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Heat conductivity</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Plasma physics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Equilibrium</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Interferometers</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Research</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pinch effect (Physics)</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Usage</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Golingo, Raymond P</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nelson, Brian A</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shumlak, Uri</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">IEEE transactions on plasma science</subfield><subfield code="d">New York, NY : IEEE, 1973</subfield><subfield code="g">43(2015), 8, Seite 2469-2479</subfield><subfield code="w">(DE-627)129391379</subfield><subfield code="w">(DE-600)184848-3</subfield><subfield code="w">(DE-576)014776553</subfield><subfield code="x">0093-3813</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:43</subfield><subfield code="g">year:2015</subfield><subfield code="g">number:8</subfield><subfield code="g">pages:2469-2479</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1109/TPS.2015.2431973</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=7112530</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://search.proquest.com/docview/1703586351</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHY</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">33.80</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">43</subfield><subfield code="j">2015</subfield><subfield code="e">8</subfield><subfield code="h">2469-2479</subfield></datafield></record></collection>

Calculation of the Equilibrium Evolution of the ZaP Flow Z -Pinch Using a Four-Chord Interferometer |
| abstract |
A four-chord interferometer and measurements from an array of surface-mounted magnetic probes were used in conjunction with equations of radial heat conduction and radial force balance to calculate the equilibrium evolution of a pinch plasma in the ZaP flow <inline-formula> <tex-math notation="LaTeX">Z </tex-math></inline-formula>-pinch. A multiple shooting method was used to solve the nonlinear coupled differential equation system, with ohmic heating and bremsstrahlung radiation as sources and sinks, respectively. Data from a single ZaP pulse are reported including profiles of magnetic field and temperature and their evolution. Profiles are dominated by high thermal conductivity near the axis which quickly decreases with radius. This is due to the plasma being weakly magnetized near the axis which increases thermal conductivity and flattens the temperature profile, but strongly magnetized near the characteristic radius, significantly reducing thermal conductivity and resulting in a large temperature gradient. The equilibrium evolution indicates that plasmas in ZaP heat and compress with increasing current as a result of magnetic compression during the quiescent period. |
