At the IGISOL-4 facility, neutron-rich, medium mass nuclei have usually been produced via charged particle-induced
fission of natural uranium and thorium. Neutron-induced fission is expected to have a higher production cross section
of the most neutron-rich species. Development of a neutron source along with a new ion guide continues to be one of
the major goals since the commissioning of IGISOL-4. Neutron intensities at di↵erent angles from a beryllium neutron
source have been measured in an on-line experiment with a 30 MeV proton beam. Recently, the new ion guide coupled to
the neutron source has been tested as well. Details of the neutron source and ion guide design together with preliminary
results from the first neutron-induced fission experiment at IGISOL-4 are presented in this report.
