“…After a week of irradiation, 99 Mo isotopes with activities of ≈ 500 TBq can be produced. Such activities are a significant improvement compared to those obtained at other facilities including some nuclear reactors [385,386]. The worldwide demand of 99 Mo isotopes is approximately 9000 6-day Ci 99 Mo per week [387], where 6-day Ci refers to activities measured 6 days after the end of target processing.…”

The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈ 400 MeV and photon fluxes (up to ≈ 10 17 photons per second) exceeding those of the currently available gamma sources by orders of magnitude. The high-energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially-stripped ions circulating in the accelerator. The secondary photons are emitted in a narrow cone and the energy of the beam can be monochromatized, eventually down to the ≈ 1 ppm level, via collimation, at the expense of the photon flux. This paper surveys the new opportunities that may be afforded by the GF in nuclear physics and related fields. CONTENTS 11.2. Photon Splitting 48 11.3. Photon Scattering 48 12.

In accelerator-driven 99 Mo/ 99m Tc production, the 100 Mo enrichment level should be chosen carefully as it greatly affects the yields of the involved Mo reactions. To facilitate selecting the 100 Mo enrichment level, we defined a figure of merit called density change coefficient and developed its calculation program. Density change coefficients calculated for nine commercial enriched 100 Mo products are presented and their use in selecting the 100 Mo enrichment level is discussed. Theory Molybdenum hierarchyWe classify Mo into three hierarchical groups as described in figure 3: (i) Mo materials, (ii) Mo element, and (iii) Mo isotopes. The Mo materials of interest in this paper were Mo metal and Mo(VI) oxide (MoO 3 ), both of which

The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈400 MeV and photon fluxes (up to ≈1017 photons s−1) exceeding those of the currently available gamma sources by orders of magnitude. The high‐energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially‐stripped ions circulating in the accelerator. The secondary photons are emitted in a narrow cone and the energy of the beam can be monochromatized, down to 10−3–10−6 level, via collimation, at the expense of the photon flux. This paper surveys the new opportunities that may be afforded by the GF in nuclear physics and related fields.
