Objective This project concerns the development of micropositioning systems to be used in beamlines for experiments with high brilliance soft x-rays synchrotron radiation machines. This is particularly the case of beamlines, such as those for microscopy, whose optical schemes require stringent accuracy tolerances, In order to obtain accuracies in the nanometric scale and compatibility with the ultra high vacuum environment, micropositioning systems are generally obtained using flexible elements. An accurate calculation of these systems involves a non-linear approach. The Eastern partner, that has a great experience in non-linear Finite Element (F.E.M.) calculations, will develop a special type of Finite Element for large displacement of very elastic beam systems. A specialized computer program will be developed and a precision analysis will be performed by comparison with commercial F.E.M. codes. Prototypes of manipulators based on flexible elements will be designed and constructed by the participants. The theoretical results obtained using the specialized F.E.M. program will be compared with experimental data in order to evaluate the accuracy of the computational approach followed. The measurement will be performed by the staff of the two participants in Sincrotrone Trieste's existing laboratories, using special set-ups based on laser interferometric techniques.
