The space-resolved spectrum emitted by a polyethylene laser produced plasma in the range 20-300 AA has been analysed. Plasma parameters, i.e. electron temperature and density, relative ion populations and plasma dimensions, have been determined. A model that takes into account Stark and Doppler broadening, Doppler shift and optical opacity, reproduces numerically the observed profiles of the Lyman lines of C VI with good accuracy and explains their build-up within the plasma.

Abstract
The space-resolved spectrum emitted by a polyethylene laser produced plasma in the range 20-300 AA has been analysed. Plasma parameters, i.e. electron temperature and density, relative ion populations and plasma dimensions, have been determined. A model that takes into account Stark and Doppler broadening, Doppler shift and optical opacity, reproduces numerically the observed profiles of the Lyman lines of C VI with good accuracy and explains their build-up within the plasma.
