- Description
- Spherical salty ice particles are produced by spraying droplets of NaCl solutions into liquid nitrogen with the SPIPA-B setup and 9mm-thick samples are produced from this material. 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.
