Scaling laws and poloidal asymmetries in the scrape-off layer of FTU
The scrape-off layer (SOL) plasma of FTU is routinely studied by means of five fast reciprocating probes, located in the poloidal plane. Each of them bears four electrodes acting as four single Langmuir probes, and is able to span the entire SOL in less than 160 msec. The whole system (the electrical and mechanical part) is remotely controlled by computer. The main aim of these diagnostics is to build a solid database allowing the study of the scaling of the main quantities relevant for the SOL, with the core plasma parameters, and the characterisation of possible poloidal assymmetries. A brief explanation of the research work undertaken is provided and the subsequent results and conclusions are presented.
