ABSTRACT
A Li-like Ti and Ca recombination x-ray laser experiment has been undertaken using the ASTERIX laser (1.3μm wavelength with 450 ps duration laser pulses) irradiating slab targets. Time-integrated X-ray spectra of helium like titanium, Ti XXI and helium like calcium, Ca XIX, resonance and satellite lines have been observed with a LiF https://www.w3.org/1998/Math/MathML"> 2 d = 4.027 Å https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003063032/9284f42f-003f-4795-89cd-da73f9068931/content/ieq0160.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> crystal spectrometer and compared to model calculations of the spectra. The electron temperatures of the Ti and Ca plasmas have been deduced along the line focus,
