Notes:
This work deals with an experimental study of the start-up phase of a mercury high-pressure discharge. We demonstrate, by using electrical and spectroscopic measurements, that a steady-state discharge can be said to be equivalent to a specific stage of the warm-up phase if, for a given current, arc voltage together with several spectral line intensities are the same in both states. Subsequently, using these measurements we were able to: (i) determine the evolution of the electric field and the voltage drop at the electrodes in the course of a start-up phase; and (ii) establish that the determination of the excitation temperature of Hg and Ar excited levels gives us a first indication concerning discharge thermalization and local thermodynamic equilibrium hypothesis limits. © 1996 American Institute of Physics.
