VIS reflectance spectra collected during electron irradiation experiments of ice particles (spherical, 67 µm average diameter) intimately mixed with NaCl particles (sieved to less than 100 µm)

Spherical ice particles are produced by spraying droplets of water into liquid nitrogen with the SPIPA-B setup. These ice particles are then intimately mixed with NaCl particles (sieved to less than 100 µm) in different concentrations and 9mm-thick samples are produced from the mixtures. The samples are then introduced into the MEFISTO chamber, placed on a liquid nitrogen cooling plate, and the chamber is evacuated to high vacuum. The samples can then be bombarded with energetic electrons at different energies and fluxes and VIS hyperspectral images are collected. Fib. 4 in Cerubini et al. (2022).

采用SPIPA-B装置将水滴喷入液氮中，制备得到球形冰粒。随后将这些冰粒与不同浓度的、筛分至粒径小于100 µm的氯化钠（NaCl）颗粒充分混合，利用所得混合物制备厚度为9 mm的样品。将样品置入MEFISTO腔室，放置于液氮冷却平台上，并将腔室抽至高真空环境。随后可利用不同能量与通量的高能电子对样品进行轰击，并采集可见（VIS）高光谱图像。该数据集相关内容可见Cerubini等人（2022）发表文献中的图4。
