Since 2011, I am an active member of the fusion programme, using ion beam techniques on Be and 3H contaminated samples from the plasma wall of the JET fusion reactor, contributing to a better understanding of the mechanisms of erosion, deposition and fuel retention and modelling these mechanisms in the life of a fusion reactor. This contribution and the ion beam analysis have resulted in about 25 articles in international journals, and the establishment of IST as a reference laboratory in the characterization of Plasma Facing Materials (PFMs). The demonstration of this relevance is the participation in international projects such as the EUROFusion project "Plasma-Wall Interaction and Exhaust", where we will contribute with the analysis of studies with ITER (W, Be) and DEMO-relevant PFMs using ion-beam techniques and the Coordinated Research Project (CRP-F11023) of IAEA, to provide a platform for efficient collaboration and transfer of knowledge between scientists from developing and developed Member States focus on the use of accelerator-based techniques for fusion-related technologies, of which I am the Portuguese Chief Scientific Investigator. Since my PhD thesis I also have been involved in research of W-alloys for applications as plasma-facing components produced by different techniques: spark plasma sintering, pulse plasma sintering, hot isostatic pressing and ion implantation. My contribution in this area was mainly focused on the production of materials by ion implantation and hydrogen retention in and hydrogen permeation through the wall materials. Another key priority of my investigations is the effects of neutron irradiation on thermal and mechanical properties and bulk tritium retention of armour materials (beryllium, tungsten). I would like to use this position to build a research line devoted to defects in diagnostic materials for future fusion reactors on a longer horizon of time, conditional upon my ability to obtain funding. With this in mind, I have proposed the installation of an irradiation module in The International Fusion Materials Irradiation Facility – Demo Oriented NEutron Source (IFMIF-DONES), a centralized Research Infrastructure for the testing, validation, and qualification of fusion reactor materials. It is based on a one-of-a-kind neutron source whose energy spectrum and flux are matched to those expected for the first wall of future fusion reactors. The start of the construction of IFMIF-DONES is expected imminent and the engagement of DECN from the start in this global-scale effort will be vital. The potential interplay between these DONES modules and well-established particle accelerator techniques for the investigation of irradiated materials should be emphasized. Despite the fact that it requires significant structural organic developments to be made possible, it is feasible and will enable IST to present a globally unique offer, resulting in a significant increase in the visibility and significance of IST in the international context of the development and application of nuclear analytical techniques, a research area of great international significance at both the fundamental and applied levels. In collaboration with Dra Marta Dias, we are currently creating the Thermophysical Properties Laboratory on CTN, using equipment provided by IST Professor Umesh Mardolcar. The goal is to study heat transfer at high temperatures in order to supplement studies and the development of materials for fusion reactors. Since the end of my doctoral studies, I remain employed at IST as a junior research contract focused on the development of protective Liquid Metal walls for PFCs in plasma reactors, as an alternative to the solid PFC and in the project FRIENDS (Fleet of dRones for radIological inspEction, commuNication anD reScue) a project dedicated to design, develop and validate a fleet of drones equipped with navigation and radiological sensors for inspection and monitoring of scenarios with nuclear threats. I also participated in several proposals for FCT and European projects, in two as a coordinator and in many others as a collaborator. Although not funded they received good evaluations.
