Abstract:
Spectroscopic techniques were employed to measure the electron density and temperature of a plasma produced by a CO2 laser at input energies close to those achieved in experiments on plasma heating by heavy ion beams in the Maxilac accelerator. The density was ~ (1–2) X 1017 cm–3, whereas the temperature was approximately 20–30 eV near the maximum of the heating radiation pulse and ~ 3 eV after the end of the pulse.
