| Keywords | Fast Neutral Lithium Beam Probe (FNLBP) Spherical Tokamak ETE fluctuation measurements |
| Abstract | A Fast Neutral Lithium Beam Probe (FNLBP) is being developed, in order, to perform measurement of the boundary plasma density in discharges of the Spherical Tokamak ETE, recently built at LAP/INPE. This plasma diagnostic method is adequate for use in fusion devices because it does not perturb the plasma and it provides data with high space and time resolution for the entire discharge lifetime. To obtain reliable measurements, however, FNLB probing depends on high signal-to-noise ratio (SIN) during beam emission spectroscopy of the Li beam injected into the plasma, specially if density fluctuation measurements are sought. Hence, our effort is been focused in the achievement of high intensity Li-0 output. Recently, probing of a low temperature (T similar to 5eV)and low density target plasma (n similar to 10(10)cm(-3)) produced in a plasma immersion ion implantation experiment (PIIIE)was performed by a 2-5keV FNLBP. The method used for the density determination of this glow discharge plasma was based on the comparison of the fluxes of 6708 Angstrom photons emitted from Li-0 beam injected into nitrogen gas that filled the PIIIE chamber and from the same beam injected into the plasma discharge. For this case, the attenuation of the beam was neglected. The plasma density measured was n(e)= 8.5 x 10(10)cm(-3)for pressure of operation of p = 7.0 x 10(-4)mbar and n(e)= 7.2 x 10(10)cm(-3)for p = 4.6 x 10(-4)mbar. These results are in good agreement with Langmuir probe data. The success of this measurement was only possible after a tenfold increase in the Li+ output and the increase of the lifetime of Li source by vitrification of the beta-eucryptite source, besides the optimization of the optical detection system and the neutralization of the beam. Presently, a new 10keV FNLBP is been developed to probe ETE plasma. For this case, where the Li beam will be strongly attenuated by the high density plasma (n(e)similar to 10(13)cm(-3)), the method of density reconstruction from the whole photon flux profile will be used. All the improvements performed during the operation of the old FNLBP device, will be implemented on this new FNLBP. |
