Recent experimental results of high gain C VI x-ray lasing in rapidly recombining plasmas are described. 7 {mu}m diameter carbon fiber targets of up to 5 mm length were irradiated at intensities between 3x10{sup 15}{approx}1x10{sup 16} W/cm{sup 2} by a 2 ps, 20 TW chirped pulse amplification (CPA) beam from the VULCAN Nd-glass laser ({lambda}=1.053 {mu}m) at RAL. The gain length product on the 18.2 nm Balmer {alpha} transition of C VI ions was measured to be 6.5{+-}1. The ratio of intensities of resonance lines of H-like and He-like ions in the rapidly recombining plasmas was used as a useful diagnostic of initial conditions for high gain operation of the C VI recombination x-ray lasing.
