Zusammenfassung:Using only time of flight data to determine energy loss, an analysis procedure has been developed to improve the precision of simultaneously measuring electronic stopping powers of swift heavy ions from a continuous energy spectrum provided by a typical elastic recoil detection analysis geometry. This procedure eliminates the well-known calibration problem of Si detectors when used with heavy ions. Consequently, the stopping powers and the energy dependence are determined with higher precision. This approach is demonstrated by measuring the stopping powers of Be, C, Si, and Br in amorphous C over a continuous range of energies. The results exhibit good agreement with limited existing data but indicate some deviations from the predicted theoretical values.
