Description
Spherical ice particles are produced by spraying droplets of salt solution into liquid nitrogen with the SPIPA-B setup. Centimeter-thick samples made of these particles are then introduced in the SCITEAS-2 simulations chamber and their slow sublimation at low temperature and in secondary vacuum is followed for several tens of hours by VIS-NIR hyperspectral imaging.
