Abstract

The MEDICIS facility at CERN aims to produce non-conventional radionuclides towards medical applications. In this work, the first collection of europium-145 (Eu-145) at CERN-MEDICIS is presented, focusing on the development and optimization of a resonance laser ionization scheme to improve isotope extraction efficiency. A two-step ionization scheme was developed and implemented, ensuring compatibility with the available laser infrastructure. The collection campaign in October 2024 successfully delivered Eu-145 for metrology studies, demonstrating the feasibility of laser-enhanced Eu ionization. The results indicate a collection efficiency of 1.85%

\pm

0.09%, although further development is in progress to optimize the ionization scheme and ion source parameters and operating conditions.

CERN-MEDICIS的第一次激光电离铕收集

欧洲核子研究中心的MEDICIS设施旨在生产用于医疗用途的非常规放射性核素。本文介绍了欧洲核子研究中心（CERN-MEDICIS）首次收集到的铕-145 (Eu-145)，重点介绍了共振激光电离方案的开发和优化，以提高同位素提取效率。开发并实施了两步电离方案，以确保与可用激光基础设施的兼容性。2024年10月的收集活动成功地为计量研究提供了Eu-145，证明了激光增强Eu电离的可行性。结果表明，在进一步优化电离方案、离子源参数和操作条件的情况下，收集效率为1.85%±0.09%。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
