Status of the TJUAMS facility

The XCAMS system at Tianjin University, operational since October 2017, has successfully analyzed over 8,000 samples for ¹⁴C, ¹⁰Be, and ²⁶Al measurements during its seven years of service. Significant improvements were achieved through the 2023–2024 installation of two automated graphitization systems, substantially enhancing ¹⁴C sample throughput. Continuous optimization of system parameters and operational protocols, guided by long-term performance data and component reliability assessments, has established robust analytical capabilities. These advancements have enabled broad applications of cosmogenic nuclides in geoscience and environmental research. This contribution details the facility’s current status, including preparation methods, performance metrics, operational results, and component evaluations.

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.
