Connected Projects


The Extreme Light Infrastructure – Nuclear Physics (ELI-NP) laboratory in Bucharest, Romania, will host an IGISOL-type facility which will study exotic neutron-rich ion beams (with special focus in refractory elements) produced via photo-fission in actinide targets placed at the center of a cryogenic gas cell. The fission fragments are the stopped and thermalized in the CSC and transported over a complex radio frequency quadrupole for radioactive ion beam formation towards a powerful multiple-reflection time-of-flight mass spectrometer where a selection of the refractory isotopes of interest will be performed to deliver a isobaric or isomeric clean beam to several measurement stations. In the picture below, a schematic view on the ELI-NP IGISOL RIB is shown.

A intense gamma beam is delivered to the gas filled CSC which contains multiple thin actinide targets. The gamma beam induces photo-fission reactions in the actinide targets and the fission fragments are then thermalized in the gas, extracted to an RFQ for beam forming and delivered to a MR-TOF-MS to tailor the desired beam delivered to the final detector.

SARAF Ion Catcher

The Soreq Applied Research Accelerator Facility (SARAF) is under construction in the Soreq Nuclear Research Center at Yavne, Israel. When completed at the beginning of the next decade, neutron-rich nuclides will be generated at SARAF via neutron induced fission on thin ^{238}U targets allocated inside a gas filled CSC. The fission fragments are then stopped and thermalized in the CSC and extracted over a radio frequency quadrupole beamline towards an MR-TOF-MS with isobaric (and even isomeric) separation and identification capabilities to tailor pure exotic beams delivered to other detectors and experimental stations located downstream.

A deuteron beam is delivered to a liquid lithium target to produce a neutron flux to irradiate the actinide targets placed inside the CSC for the production of exotic nuclei via neutron-induced fission. The exotic nuclei are then extracted towards an RFQ beamline to an MR-TOF-MS, where the selection of the desired nuclei is performed and delivered to other detectors and experimental stations located downstream.
