Photonuclear reactions on titanium targets of natural composition at the bremsstrahlung endpoint energy of 30 and 40 MeV have been investigated. The yields of Sc at the end of the bombardment were measured to be (0.45 ± 0.07) MBq/(μA h g) and (1.34 ± 0.12) MBq/(μA h g) for 30 and 40 MeV, respectively. Cross-sections per equivalent quantum of the reactions Ti(γ,x)Sc and Ti(γ,xn)Ti were measured.

With the usage of the postcompression technique, few-cycle joule-class laser pulses are nowadays available extending the state of the art of 100 TW-class laser working at 10 Hz repetition. In this Letter, we explore the potential of wakefield acceleration when driven with such pulses. The numerical modeling predicts that 50% of the laser pulse energy can be transferred into electrons with energy above 15 MeV, and with charge exceeding several nanocoulombs for the electrons at hundreds of MeV energy.

Based on analytical description of isotope production by bremsstrahlung (X-ray) radiation, an algorithm is proposed for calculating the optimal dimensions of a cylindrical target of given mass positioned at a given distance from a bremsstrahlung converter to ensure the maximum yield of the isotope product. The expressions are derived for the total activity and its distribution along the target axis. A technique of γ-spectrometric measuring the activity of a thick production target is proposed.

The detection of high-flux gamma beams from laser plasma interactions is always hampered by signal pileup. In this study, a gamma threshold detector based on the bubble chamber is designed to detect high-flux gamma beams. Through simulations, it has been demonstrated that this detector can detect gamma rays with energies above 5 MeV through photonuclear reactions, even at fluences as high as 1011 photons/cm2.

Background: Actinium-225 is one of the most promising radionuclides for targeted alpha therapy. Its limited availability significantly restricts clinical trials and potential applications of Ac-based radiopharmaceuticals.
Methods: In this work, we examine the possibility of Ac production from the thermal neutron flux of a nuclear reactor.
Production of Sn and Sn by photonuclear reactions on natural antimony.
Appl Radiat Isot

A.Alikhanyan National Science Laboratory (Yerevan Physics Institute), Yerevan, Armenia.
Natural antimony targets were irradiated in a 60 MeV bremsstrahlung beam and gamma spectrometric measurements were performed. The goal was to establish the yield of Sn, a radionuclide with great potential for application in medicine. Considering that Sn is predominantly produced through a photonuclear reaction in which an charged particle is emitted (Sb(γ,p3n)), the yield of this tin isotope is much lower than the yields of several antimony isotopes produced in (γ,xn) reactions.
