Design and construction of S-band linear accelerator in Institute for research in fundamental science (IPM), is one of the successful experiences in design and construction of accelerators in Iran. Since brazing method has not been used for construction of such a system, copper remains hard during manufacturing process and hence this method would be a better candidate for construction of high gradient cavities. In addition, relatively low cost of such method will result in spread of high-gradient technology. Plans for this project consist of radiofrequency and mechanical design of cavities with Shrinking fit, Clamping and Vacuum Brazing method. After cold and hot test of cavities in Iran, high gradient test such as Breakdown Rate will be carried out in SBOX RF test stand at CERN.
