OSTI ID:5526776
Spectral emission lines from an H/sup -/ Penning surface-plasma source (SPS), the 4X source, are examined in the visible and near ultraviolet. Electron distribution temperatures are deduced from integral line-strength measurements. These temperatures are surprisingly low, about 0.5 eV. Electron density values of about 1.5 x 10/sup 14/ cm/sup -3/ and H-atom energies between 2 and 2.6 eV are determined from the measured Balmer-line profiles. Assuming the H/sup -/ energy is identical to the H-atom energy, an emittance limit of 0.006 ..pi.. x cm x mrad is deduced for this source with a 5.4-mm aperture.
