In this research, a theoretical study for calculation of the range of protons with energy (2-10MeV) when passing in the superconductor media (Ti, Mo, Sn and W). The range of proton were calculated by using A. K. CHAUBEY and H. V. GUPTA equation, SRIM 2012 program ,PASTR programs, and then by using a semi empirical equation we got for calculating least square method . We get a good agreement among these results. As well as that we calculate the maximum difference between the semi empirical calculation and with all results by using the statistical test ( kstest2) in Matlab program .
