Laboratory Search for Fe IX Solar Diagnostic Lines Using an Electron Beam Ion Trap
نویسندگان
چکیده
The Fe IX spectrum features two lines in the extreme ultraviolet whose ratio has been rated among best density diagnostics solar spectrum. One line is an E1-allowed intercombination transition at 244.909 Å, other E1-forbidden M2 241.739 Å. Employing a medium and high resolution spectrometer Livermore EBIT-I electron beam ion trap, we have observed pair laboratory for first time. Using CHIANTI model computation, yields value of that compatible with typical densities our device.

Laboratory Astrophysics Survey Of Key X-Ray Diagnostic Lines Using A Microcalorimeter On An Electron Beam Ion Trap
Cosmic plasma conditions created in an Electron Beam Ion Trap (EBIT) make it possible to simulate the dependencies of key diagnostic X-Ray lines on density, temperature, and excitation conditions that exist in astrophysical sources. We used a microcalorimeter for such laboratory astrophysics studies because it has a resolving power .1000, quantum efficiency approaching 100% and a bandwidth that...
متن کاملSimulating a Maxwellian plasma using an electron beam ion trap
We describe a technique for producing a Maxwell–Boltzmann electron energy distribution using an electron beam ion trap ~EBIT!. The technique was implemented on the Lawrence Livermore EBIT to simulate Maxwellian plasmas. We discuss technical and experimental issues related to these simulations. To verify the fidelity of the quasi-Maxwellian, we have measured line emission due to dielectronic rec...
متن کاملAn electron beam ion trap for the NSCL reaccelerator
The reacceleration of stopped fast-fragment beams or low-energy ISOL beams to the energy range of 0.3–12 MeV/nucleon allows for experiments such as low-energy Coulomb excitation and transfer reaction studies and for the precise study of astrophysical reactions. The coupling of a reaccelerator to a gas stopper at a fragmentation facility will provide rare isotope beams of nuclides not available ...
متن کاملAbsolute measurement of the resonance lines in heliumlike vanadium on an electron-beam ion trap
Absolute measurements of the energies of resonance lines in heliumlike vanadium on an electron-beam ion trap are reported. The 1s2p P1→1s, 1s2p P2→1s ~1s2p P1→1s and 1s2p P0→1s! blend and 1s2s S1→1s transitions are 5205.10 6 0.14 eV, 5189.12 6 0.21 eV, 5180.22 6 0.17 eV, and 5153.82 6 0.14 eV, respectively. This agrees with recent theoretical calculations and the experimental precision lies at ...
متن کاملEUV Spectroscopy of Xenon Ions Created Using an Electron Beam Ion Trap
Laser-produced plasma source development for Extreme Ultra Violet (EUV) lithography has concentrated on xenon, since XeXI emits at 13.5 nm, the wavelength at which the reflectivity of MoSi mirrors is centred. However it is not obvious that the required conversion efficiencies can be achieved using xenon, and tin has been identified as a strong emitter at this wavelength. The transitions respons...
