Vacuum Spark

X-ray radiation is obtained from a point plasma produced by pinch effect Cohen et al. (1968) in a vacuum spark similar to that used by Lie and Elton (1971) with a 220 kA peak current. The extremely dense and hot minute plasma appears at a distance of 0.5 to 1 mm from the anode tip and has maximum dimensions of a few microns.The spectroscopic observations are performed by means of a focusing Cauchois spectrometer so as to avoid effects of fluctuations in the source position.

Vacuum Spark

The spectrum of the TFR Tokamak has been observed in the range 5-100 Å. Identification of Mo XIV to Mo XXXIII lines originating from the limiter was achieved by comparison with the Mo spectrum emitted from a low-inductance vacuum spark, and with relativistic calculations. Some of the TFR lines were identified as forbidden transitions (electric quadrupole). The appearance of these lines depending on plasma parameters is discussed.

Vacuum Spark

The spectra of Ne-like ions of Ba, La, Ce, and Pr in the 1.9 – 2.7 Å region, excited in the low-inductance vacuum spark plasma, have been obtained for the first time. A Johann's crystal spectrograph in combination with an image intensifier was used for recording the spectra. The 2s22p6 – 2s2p63p and 2s22p6 – 2s22p53d transitions have been identified in these ions along with the satellite lines of Na-like and Mg-like Ba–Pr ions.
