Resumen
The aim of this work is to describe a theta-pinch for spectroscopic studies. This machine is different in some aspects from its equivalent for fusion studies. Here, in a single experiment, 1000 shots are used normally. The capacitor bank stores 14 kJ of electrical energy at 60 kV, but only 1 kJ is necessary to obtain an electron peak temperature of 150 eV, which is enough to produce a good emission spectrum in the VUV range of 300 to 2000 Angstrom. With this device it is possible to obtain intermediate ionization states of many elements (ionized six or seven times), Similarly to tokamaks, the theta-pinch spectrum contains spectral lines due to Forbidden transitions, where the Delta S = 0 rule for dipole electric transition is violated. 31 7 866 872
