A new method to investigate thin wires has been tested, which is based on a special sample holder and on a high energy X-rays. Due to the high penetration power of high energy Xrays quantitative texture data will be obtained without any additional corrections such as constant volume correction and absorption correction. The measurements have been carried out at the high energy beam line BW5 at HASYLAB - DESY (Hamburg). In order to overcome grain statistics problems on the investigated Cu-wire of 122 mu m thickness a special scanning routine together with the sample preparation allows to average over a wire length between l mm and up to 240 mm.
