Two methods of target technology for investigation of X-ray laser-plasma emission are presented. The first deals with steel and gold microcapillary targets. They are about 200 mum in inner diameter and about 500 mum in length. The second method deals with metal plus plastic targets of reduced and controlled density in the range of 1.6-8.1 g/cm3 for Cu + polyethylene (PE) and 1.6-7.6 g/cm3 for Fe + PE.
