This unique program is designed to bridge the interaction gap between the young theorists and experimentalists in condensed matter physics as an advanced training at the upper graduate and postgraduate level. The lectures will focus on certain fundamentally important condensed matter physics experimental methods and the physics of major effects measured by these methods. Six important  measurement techniques are planned to be covered with each of the topics including several hours of advanced lectures stressing the theory-experiment relations aiming at the understanding of the material in depth by the participants.
