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

Abstract

Semi-empirical fitting based on classical Bohr theory has been applied to the experimental LET data in silicon of the RADEF heavy ion cocktail species. The parameterized LET descriptions to be used in the European Component Irradiation Facilities are introduced and compared with the commonly used estimations from SRIM-code. Also, a new user interface, ECIF Cocktail Calculator, based on this work, has been published under the RADEF webpages at http://www.jyu.fi/accelerator/radef/ECIFCalc.

Methodologies for the Statistical Analysis of Memory Response to Radiation

“…The proton energies used at RADEF ranged from 100keV to 6MeV for LEP tests [2], and from 6MeV to 55MeV for HEP. The LET of the heavy ions used at HIF ranged from 3.3 to 67.7 MeV.cm 2 .mg -1 [3], whereas the LET of the heavy ions used at RADEF ranged from 1.9 to 60 MeV.cm 2 for the various types of heavy ions. Irradiation time varied from several seconds to a few minutes for ions, and from a few minutes to a few hours for neutrons.…”
