Biography

Research and academic activities at IST/IPFN At IPFN I work mainly on the developments of the heavy ion beam diagnostic. I am responsible for the numerical modelling, design, upgrades and commissioning of the Heavy Ion Beam Diagnostic for the ISTTOK tokamak in operation since 1992. The main difference to previous arrangements was the implementation of a 2D matrix cell detector to collect the complete fan of probing ions exiting the plasma. This new approach opened the possibility for the simultaneous measurement of electron density and temperature, plasma potential and internal magnetic field profiles with their temporal evolution. I am supervising a PhD student in implementing new developments for the HIBD diagnostic system in order to measure density fluctuations to characterize MHD activity and turbulence and performing cross checks with Mirnov coils and Langmuir probes. I am also supervising a PhD student working on the implementation of a new detection system in order to provide the simoultaneos measurements of plasma potential, plasma poloidal magnetic field and plasma density radial profiles and their fluctuations up to 250 kHz. This is based on a new concept using a combination of two multiple cell detectors and a cylindrical electrostatic energy analyser. International Collaborations From 1995 to 1996, I developed a conceptual study for an HIBD on the Stellarator TJ-II at CIEMAT, Madrid. The simulation code was integrated with the TJ-II magnetic field calculation routines. Due to higher beam attenuation effects the 3rd ionization needed to be include in the simulation (Cs++e->Cs2++2e-, Cs++e->Cs3++3e- e Cs2++e->Cs3++2e-). I conceived and designed a new detection system based on the combination of a 2D multiple-cell detector and an electrostatic energy analyzer. In 1995, developed a conceptual study for an HIBD for the Spherical Tokamak MAST at Culham. Now in 2013, this activity has regain interest and I developed new simulations in order to support study the possibility to implement a HIBD for MAST-Upgrade by 2014/15. I have also been involved in the development of Laser Induced Breakdown Spectroscopy methods (similar system is used in Mars rover Opportunity) and analysis for Tritium and deposit composition monitoring in fusion devices. • Work at ITER International Team - Garching (4 years) From Jan. 2000 to end of Dec. 2003 I worked at ITER-Garching JWS, Germany. I was responsible for coordinating the physics design and the integration of the active and passive spectroscopic diagnostics (visible CXRS and MSE, UV, XUV and imaging hard X-ray) and the vacuum extended diagnostic systems into ITER (NPA, VUV). • Work at the IAEA ( 5 Years) Since Jan. 2004 to Jan. 2009 I worked at the International Atomic Energy Agency (grade P4) where I was responsible for the activities of the IAEA Fusion sub-programme. The work was devoted to organize and coordinate research projects in the area of Fusion, plan and held technical meetings and set-up consultancy meetings for supporting coordinated research projects. • Work at EFDA in Garching (October 2009-August 2011) I was working as Coordinator (Programme Responsible Officer) for the Emerging Technologies Programmes on: i) Dust and Tritium Inventory and Removal, ii) High Temperature Superconductors for DEMO and Fusion Power Plants. I was also responsible for the management of 3 large EU training programmes (GOT – Goal Oriented Training) and three biannual fellowships. • JET-EFDA Culham (UK) (secondment since August 2011-September 2013) I was responsible for the Public Relations office at JET (4 months) and for managing the peer review and clearance of publications for all JET papers and conference communications. In support of knowledge and results dissemination I was responsible to organize seminars, scientific meetings and rehearsals of oral and poster presentations to international conferences. • Other activities At present I am the coordinator for the Portuguese contribution (4 PhD, 2 Eng.) for the DEMO project on Diagnostics and Control. The activities are addressing the development and design of interface concepts between diagnostics and other tokamak systems (breading blanket, remote handling, vessel, cryostat, pit and safety) I am appointed (2015) member of the Technical Advisory Committee for Fusion for Energy I am responsible for teaching (Assistant Professor) on the Physics Department of the Instituto Superior Técnico experimental and theoretical physics on the subjects of Electromagnetism and Mechanics.
