Luís Lemos Alves

My field of work is the modelling and simulation of low-temperature plasmas. I use a research methodology that starts by formulating the problem, continues with the development / updating of a numerical tool, including its verification through benchmarking against other codes, and concludes with the validation of the physical model by comparison with experiments. Over the years I have developed many different numerical codes, extending from the numerical solution of the electron Boltzmann equation to the development of multi-dimensional dynamic models for reactive gas/plasma systems. My research focuses on the study of microwave and radio-frequency discharges, of interest for material science, biological and environmental applications.

Artur Malaquias

At IPFN I am responsible for the heavy ion beam diagnostic team. This diagnostic was installed in 1992 for the measurement of several plasma parameters of the ISTTOK tokamak. My interests are in the numerical modelling, data analysis, design and commissioning of upgrades. The main difference to previous arrangements of the ISTTOK-HIBD relies on the use 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. Other research interests include participation in European fusion projects in other tokamaks: JET, ITER and DEMO.
