/ISOLDE
The properties and performance of TiN thin films are closely related to the concentration and mobility of lattice defects in the thin film structures of TiN. This makes a local atomic scale study of TiN thin films an ever-growing demand. [...]

Magnetic field at Ce impurities in La sites of La$_{0.5}$Ba$_{0.5}$MnO$_{3}$ double perovskites
/ Bosch-Santos, B (Sao Paulo U.) ; Nascimento, N M (Sao Paulo U.) ; Saiki, M (Sao Paulo U.) ; Correa, E L (Sao Paulo U.) ; Sales, T S N (Sao Paulo U.) ; Pereira, L F D (Sao Paulo U.) ; Cabrera-Pasca, G A (Para U.) ; Saxena, R N (Sao Paulo U.) ; Schell, J (Duisburg-Essen U. ; CERN) ; Carbonari, A W (Sao Paulo U.)
Due to its rich variety of electromagnetic properties, such as a colossal magnetoresistance, charge and orbital ordering, and metal-insulator transition, the magnetic behavior in La$_{0.5}$Ba$_{0.5}$MnO$_{3}$ double perovskite compounds has been investigated by several techniques, however more experimental data, especially from atomic resolution techniques, are still necessary to understand such complex behavior. In this paper, we have used a nuclear and short-range technique, the Perturbed Angular Correlation (PAC) spectroscopy, to investigate the magnetic hyperfine interaction at the $^{140}$Ce and $^{111}$Cd probe nuclei as impurities occupying La sites.

Chemical Purification of Terbium-155 from Pseudo-Isobaric Impurities in a Mass Separated Source Produced at CERN
/ Webster, Ben (Teddington, Natl. Phys. Lab ; Surrey U.) ; Ivanov, Peter (Teddington, Natl. Phys. Lab) ; Russell, Ben (Teddington, Natl. Phys. Lab) ; Collins, Sean (Teddington, Natl. Phys. Lab) ; Stora, Thierry (CERN) ; Ramos, Joao Pedro (CERN ; Leuven U.) ; Köster, Ulli (Laue-Langevin Inst.) ; Robinson, Andrew Paul (Teddington, Natl. Phys. Lab ; Manchester U.) ; Read, David (Teddington, Natl. Phys. Lab ; Surrey U.)
Four terbium radioisotopes ($^{149, 152, 155, 161}$Tb) constitute a potential theranostic quartet for cancer treatment but require any derived radiopharmaceutical to be essentially free of impurities. Terbium-155 prepared by proton irradiation and on-line mass separation at the CERN-ISOLDE and CERN-MEDICIS facilities contains radioactive$^{139}$Ce$^{16}$O and also zinc or gold, depending on the catcher foil used.

Rapid growth of organic aerosol nanoparticles over a wide tropospheric temperature range
/ Stolzenburg, Dominik (Vienna U.) ; Fischer, Lukas (Innsbruck U.) ; Vogel, Alexander L (Frankfurt U. ; CERN ; PSI, Villigen) ; Heinritzi, Martin (Frankfurt U.) ; Schervish, Meredith (Carnegie Mellon U.) ; Simon, Mario (Frankfurt U.) ; Wagner, Andrea C (Frankfurt U.) ; Dada, Lubna (Helsinki U.) ; Ahonen, Lauri R (Helsinki U.) ; Amorim, Antonio (Lisbon U. ; CMAF, Lisbon) et al.
Nucleation and growth of aerosol particles from atmospheric vapors constitutes a major source of global cloud condensation nuclei (CCN). The fraction of newly formed particles that reaches CCN sizes is highly sensitive to particle growth rates, especially for particle sizes <10 nm, where coagulation losses to larger aerosol particles are greatest.

/BGV
The beam-gas vertex (BGV) detector is an innovative instrument measuring noninvasively the transverse beam size in the Large Hadron Collider (LHC) using reconstructed tracks from beam-gas interactions. The BGV detector was installed in 2016 as part of the R&D; for the High-Luminosity LHC project. [...]

Development of the SLRI beam test facility for characterization of monolithic active pixel sensors

Synchrotron Light Research Institute (SLRI) has successfully constructed a new experimental station, a Beam Test Facility (BTF), to the current SLRI accelerator complex. SLRI-BTF is capable of producing electron test beams with the number of electrons ranging from a few to millions of electrons per spill and with tunable energy from 40 MeV up to 1.2 GeV. [...]

Alternative approach to populate and study the $^{229}$Th nuclear clock isomer
/ Verlinde, M. (Leuven U.) ; Kraemer, S. (Leuven U.) ; Moens, J. (Leuven U.) ; Chrysalidis, K. (CERN) ; Correia, J.G. (Lisbon, IST) ; Cottenier, S. (U. Gent (main) ; Unlisted, BE) ; De Witte, H.

A new approach to observe the radiative decay of the $^{229}$Th nuclear isomer, and to determine its energy and radiative lifetime, is presented. Situated at a uniquely low excitation energy, this nuclear state might be a key ingredient for the development of a nuclear clock, a nuclear laser and the search for time variations of the fundamental constants.
