 Monte-Carlo simulation with FLUKA for solid Mo-100 target / Infantino, A (CERN) ; Hoehr, C (TRIUMF) The influence of proton beam profile and beam angle impinging a solid Mo-100 target at 24 MeV has been studied with the Monte-Carlo code FLUKA. The yield of Tc-99m is dependent on both the profile and the angle, with the extreme case of a reduction of the yield by about 50% when a more realistic Gaussian beam was used and a beam angle of 60° to the normal of the target plate.. 2017 - 5p. - Published in : AIP Conf.

 Neutron-induced fission cross-section measurement of 234U with quasi-monoenergetic beams in the keV and MeV range using micromegas detectors / Tsinganis, A (CERN) ; Kokkoris, M (Natl. Tech. U., Athens) ; Vlastou, R (Natl. Tech. U., Athens) ; Kalamara, A (Natl. Tech. U., Athens) ; Stamatopoulos, A (Natl. Tech. U., Athens) ; Kanellakopoulos, A (Natl. Tech. U., Athens) ; Lagoyannis, A (National Centre for Scientific Research ‘Demokritos’, Athens) ; Axiotis, M (National Centre for Scientific Research ‘Demokritos’, Athens) Accurate data on neutron-induced fission cross-sections of actinides are essential for the design of advanced nuclear reactors based either on fast neutron spectra or alternative fuel cycles, as well as for the reduction of safety margins of existing and future conventional facilities. The fission cross-section of $^{234}$U was measured at incident neutron energies of 560 and 660 keV and 7.5 MeV with a setup based on ‘microbulk’ Micromegas detectors and the same samples previously used for the measurement performed at the CERN n_TOF facility (Karadimos et al., 2014).

 Particle physics: No sign of asymmetry in the strong force / Dobrin, Alexandru Florin (CERN) The strong force binds the constituents of nuclei together. Differences between the force's fundamental interactions and their mirror images were thought to have been observed in heavy-ion collisions, but new data challenge this picture.. 2017 - 3 p. - Published in : Nature 546 (2017) 477-479
