Calculated Response of a Linear Energy Transfer Spectrometer (LETS) Correlation with Relative Biological Effectiveness and Quality Factors.

Abstract

Several computer codes have been written and applied to the problem of predicting the response of the AFWL Linear Energy Transfer Spectrometer (LETS) which has been built for use on Skylab. In addition, RBE and QF have been calculated for the same charged particle spectra and spacecraft shielding to calculate response of the LETS. The computer programs developed include a range and energy loss code, an energy limit code, a flux determination code and RBE/QF code. The energy spectra of protons and alpha particles external to the spacecraft were assumed to be exponential in nature. Calculations were performed over a wide e-fold range, from 10 to 999 Mev. Also, degraded spectra were employed for a wide range of spacecraft shielding thicknesses, up to 8.0 g/sq cm. Data are presented on results of these calculations, including predicted relative counting rates in the seven channels of the LET spectrometer. (Author)
