The objective of this internship is to take advantage of the new possibilities offered by the dynamic diamond anvil cell, an innovative dynamic compression device, to demonstrate novel phenomena or gain a detailed understanding of certain effects discussed in the literature, by performing ultrafast pressure variations. The work will focus on studying the nucleation kinetics of noble gases (Ar, Ne, Kr) as a function of the compression rate, and on comparing the results with recent measurements carried out at the XFEL in cryogenic jets. A PhD may be pursued following this internship.
