Research topics
- Study of Edge Plasma Physics in Tokamaks, focusing on the Power Exhaust and Pumping problems in the next generation of experiments. With the development of the next generation of Tokamak machines, the power to be handled by solid components will reach unprecedented levels. Lacking of an efficient design, the steady-state heat flux density to exhaust could reach values of several tens (or hundreds) of MW/m2, similar to the values characteristic of the sun surface. In the occurrence of incidental conditions (e.g. disruptions) the above value could temporarily increase by a few orders of magnitude, although for time durations limited to a few milli-seconds. The international fusion community is producing a massive effort to develop an effective design of the divertor, which is the Tokamak component devoted to receive the steady-state fluxes. Moreover, it is mandatory to protect also the remaining part of the wall from the transient loads, without compromising its capacity to allow an efficient transmission of the neutronic flux. Should the wall impede an efficient neutron transmission from the central reactor region to the blanket, the processes leading to Tritium production could be damaged. With a too low Tritium Breeding Ratio (TBR) the fuel cycle could not be closed. A comprehensive approach to the problem implies both studies of Plasma Physics (which is my main scientific interest) and material science. On this, I cooperate actively with the major institutions active in Italy (the DTT consortium, currently building the next italian experimental reactor in Frascati), in Europe (e.g. EUROFusion, which is designing the DEMO reactor. It is thought to produce electricity in the second half of this century) and some private companies (Eni in Italy, the Commonwealth Fusion System (CFS) in US, Tokamak Energy (TE) in UK)). In particular, I am active since several years to produce numerical simulations of several divertor configurations for different Tokamaks. Also, I work on the study of disruption phenomena, with focus on developing proper avoidance and mitigation strategies. Since 2015, I had supervised about ten MSc and several PhD thesis projects on the subject.
