We supply the modelers with a database, SpuBase (doi:10.5281/zenodo.10783295), that is based on the latest approach for obtaining solar wind ion sputter yields in agreement with experimental sputter data outlined in Jäggi et al. We include an overview of sputter results for typical Lunar and Hermean surfaces. To obtain total sputter yields for any given surface, we perform a mass balance of individual mineral sputter yields. For a set of impact angles, the angular and energy distribution data are scaled according to the sputter yield, summed up and fitted to obtain one probability distribution for each chemical element involved. Comparison of the results from different geochemical terranes on the Moon and Mercury has shown that variations in the abundance of silicates result in comparable energy and angular distribution data owing to the underlying model assumptions. The inclusion of sulfides relevant for Mercury, however, significantly affects the energy and angular distributions of sputtered particles. The application of the damage-driven sulfur diffusion rate in FeS in all sulfur-bearing minerals results in 35 times lower sulfur yields on average and a less prominent forward sputtering of sulfur at grazing incidence angles.

SpuBase：用于建模目的的太阳风离子溅射数据库

我们为建模者提供数据库 SpuBase (doi:10.5281/泽诺多.10783295），这是基于获得太阳风离子溅射产率的最新方法，与 Jäggi 等人中概述的实验溅射数据一致。我们概述了典型月球和赫米亚表面的溅射结果。为了获得任何给定表面的总溅射产额，我们对各个矿物溅射产额进行质量平衡。对于一组冲击角度，根据溅射产率对角度和能量分布数据进行缩放、求和并拟合，以获得所涉及的每种化学元素的一个概率分布。月球和水星上不同地球化学地体结果的比较表明，由于基本模型假设，硅酸盐丰度的变化导致了可比较的能量和角度分布数据。然而，包含与汞相关的硫化物会显着影响溅射粒子的能量和角度分布。在所有含硫矿物的 FeS 中应用损伤驱动的硫扩散速率，导致硫产率平均降低 35 倍，并且在掠入射角处硫的前向溅射不太明显。
