Energy loss of 40Ar in Au: Comparison of TOF-E and TOF-TOF method

Energy loss of 40Ar ions in Au has been measured using two methods: TOF-E and TOF-TOF. The two methods are compared and discussed. The final results cover energy range 2-445 MeV (0.05-11 MeV/u) and give satisfactory agreement with SRIM 2003 predictions. Statistical error of the data is at the level of 1-2%.
