“…E.g. the bench-mark nucleus 132 Sn is well produced in low-energy fission with the "classical" double-hump mass distribution whereas production of 140 Sn benefits from the flatter mass distribution in high-energy fission [36]. Fragmentation reactions on the other hand can be depicted as removal of nucleons in a statistical manner through quasi-free nucleon-nucleon collisions.…”

“…In the design of the RIA facility, projectile-fragmentation reactions induced by stable nuclear beams and in-flight separation as well as the use of a gas catcher have been considered to overcome this problem, see, e.g., Ref. [17]. As already mentioned, for the EURISOL project, the fragmentation and in-flight separation of a reaccelerated neutron-rich ISOL beam [10] is being investigated, which should allow producing extremely neutron-rich nuclides.…”

“…In the highpower fission-target option, secondary neutrons from a converter target induce fission in a uranium or thorium target at excitation energies mostly up to a few MeV above the fission barrier. Neutron-induced fission was also considered as one of the neutron-rich nuclide production mechanisms for RIA, and some estimates of possible beam intensities can be found in [17].…”

“…In the latest design of RIA, a deuteron beam up to 800 MeV and a beam power of 100 kW were considered as one of the different options, however due to the target geometry used, the production mostly relies on fission by low-energy neutrons in the range from 0.5 to 3 MeV [60], thus providing a nuclide distribution similar to the one obtained in the EURISOL proton-converter option.…”

Possibilities are studied for the optimization of EURISOL rare nuclide yields in specific regions of the nuclear chart by building the driver accelerator in a way that enables accelerating several additional beam species, to specific energies, besides the baseline 1 GeV proton beam. Nuclide production rates with these driver beams are compared to the production rates expected with the 1 GeV proton beam in the directproduction and the high-power-converter scenarios. Arguments are presented to show that several additional driver-beam scenarios could provide substantial benefit for the production of nuclides in specific regions of the nuclear chart. The quantitative values in this report are preliminary in the sense that they depend on assumptions on the values of some key parameters which are subject to technical development, e.g., maximum beam intensities or limits on the target heat load. The different scenarios are compared from the aspect of nuclide yields. The arguments presented here, when complemented by the corresponding technological and financial considerations, are intended to serve as a part of the basis for decisions on the design of the driver accelerator of EURISOL.

“…The production of intense highly charged uranium (U) ion beams is imperative for producing intense radioactive isotope (RI) beams at numerous accelerator facilities [1][2][3] because of the exceptional efficiency of RI production achieved through the in-flight fission of U ions [4]. Therefore, new superconducting ECR ion sources were constructed, successfully generating an intense beam of highly charged U ions.…”

Intense highly charged uranium (U) ion beams were produced using RIKEN 28 GHz superconducting electron cyclotron resonance (ECR) ion source in a high-temperature oven (HTO). We used a double-oven system to ensure ample vapor supply. Moreover, we optimized the vapor delivery into the plasma at a constant microwave power input. Consequently, we achieved intense U-ion beams, specifically 250 eμA for U35+, 36 eμA for U46+, and 10 eμA for U54+, at an injected microwave power of approximately 3000 W. This achievement stems from recent advancements, notably the optimization of the material consumption rates aimed at maximizing beam intensity, which we briefly review here.
