The cryogenic stopping cell of the IGISOL facility at ELI-NP

An IGISOL beamline that produces neutron-rich nuclei via photo-fission induced by a high-brilliance gamma beam is being developed at the Extreme Light Infrastructure - Nuclear Physics (ELI-NP) facility. The core device will be a cryogenic stopping cell with an actinide target system in its center. We report on some of the latest simulation results for an optimal design of this gas cell.
