Yields of fission products from various uranium and thorium targets

Developing uranium dicarbide–graphite porous materials for the SPES project

“…As tested in the past at ISOLDE [1] and recently studied at HRIBF [2], uranium carbide (namely UC x , with 1 6 x 6 2) dispersed in excess graphite is the ideal candidate as target material for the production of RIB. Even though the release of nuclear reactions products has been extensively studied for RIB production [2,3] the reasons for the good release properties of this material are not yet fully understood.…”

“…(1) to have large cross section and diffusion coefficient; (2) to work at the highest possible operating temperature, defined as the temperature at which its vapor pressure begins to affect the ionization efficiency of the ion source used in the exotic ions generation;…”

“…For instance, there has been some confusion about whether target material is UC or UC 2 [2]. Since the material composition and morphology are strictly dependent on processing conditions, and several methods have been so far employed for the production of the uranium carbide targets for RIB production, some uncertainties exist on the actual properties of the final material.…”

ISOL yield predictions from holdup-time measurements

“…In this paper, we report on measurements made on only two targets: a 6325 mesh (43 lm) target and a 6400 mesh (37 lm) target, both produced at Argonne National Laboratory [9]. We consider only these two targets because an extensive set of yield measurements were performed much earlier on these same targets [10,11]. Half-life values were obtained from the on-line Table of Isotopes [12], and values for the isotope-production rates were calculated by Zhao [13].…”
