A white neutron source based on the Be(p, nx) reaction for fission studies at the IGISOL-JYFLTRAP facility has been designed and tested. 30MeV protons impinge on a 5mm thick water-cooled beryllium disc. The source was designed to produce at least 1012 fast neutrons/s on a secondary fission target, in order to reach competitive production rates of fission products far from the valley of stability. The Monte Carlo codes MCNPX and FLUKA were used in the design phase to simulate the neutron energy spectra. Two experiments to characterise the neutron field were performed: the first was carried out at The Svedberg Laboratory in Uppsala (SE), using an Extended-Range Bonner Sphere Spectrometer and a liquid scintillator which used the time-of-flight (TOF) method to determine the energy of the neutrons; the second employed Thin-Film Breakdown Counters for the measurement of the TOF, and activation foils, at the IGISOL facility in Jyväskylä (FI). Design considerations and the results of the two characterisation measurements are presented, providing benchmarks for the simulations.

Precision Mass Measurements on Neutron-Rich Rare-Earth Isotopes at JYFLTRAP : Reduced Neutron Pairing and Implications for r-Process Calculations
Vilén, Markus; Kelly, J. M.; Kankainen, Anu; Brodeur, M.; Aprahamian, A.; Canete, Laetitia; Eronen, Tommi; Jokinen, Ari; Kuta, T.; Moore, Iain; Mumpower, M.

S.; Rinta-Antila, Sami; Surman, R.; Voss, Annika; Äystö, Juha (American Physical Society, 2018)The rare-earth peak in the r-process abundance pattern depends sensitively on both the astrophysical conditions and subtle changes in nuclear structure in the region. This work takes an important step towards elucidating ... -
Nuclear fission studies with the IGISOL method and JYFLTRAP
Gorelov, Dmitry (University of Jyväskylä, 2015)there is no unique model or theory which describes all aspects of this phenomenon. Experimental measurements of nuclear fission product distributions still remains quite a challenging task for modern technologies. In ...
