Experimental Linear Energy Transfer of heavy ions in silicon for RADEF cocktail species

Abstract

Experimental Linear Energy Transfer values of heavy ions in silicon are presented with comparison to estimations from different semi empirical codes widely used among the community. This paper completes the LET data for the RADEF cocktail ions in silicon.

Semi-empirical LET descriptions of heavy ions used in the European Component Irradiation Facilities

“…As mentioned in our previous publications [5], [6] the largest discrepancy between the SRIM estimations and the experimental data is observed for the heaviest ions, i.e. Kr and Xe in our case.…”

“…The experimental data for LET in Si, published in [5], [6], are described via adaption of semi-empirical formula introduced in [7]. This procedure is based on the classical Bohr theory for electronic stopping.…”

“…The linear energy transfer (LET) in silicon for the ions included in the RADEF heavy ion cocktail have been experimentally defined and published in [5], [6]. This paper presents an adaption of semi-empirical formula, presented in [7], to these LET data.…”

Semi-Empirical LET Descriptions of Heavy Ions Used in the European Component Irradiation Facilities

“…LET LET LET (6) In (6), is the number of experimental data points for the ion in question, LET and LET are the experimental LET value and the corresponding LET value from the fit at a given energy , respectively. The parameterized LET in silicon with the experimental data for each of the RADEF ions are presented in Fig.…”

“…The common ions are highlighted. The linear energy transfer (LET) in silicon for the ions included in the RADEF heavy ion cocktail have been experimentally defined and published in [5], [6]. This paper presents an adaption of semi-empirical formula, presented in [7], to these LET data.…”
