N2 - Density structures elongated along the magnetic field lines, so-called blobs, are able to contribute significantly to the scrape-off layer (SOL) transport in magnetically confined fusion plasmas. Thus, understanding of generation and dynamics of blobs is needed to predict the particle and energy flux to the walls of a future fusion reactor. Although the understanding of blobs has improved a lot over the recent years [1, 2], the details about both, blob generation and evolution remain still unknown. In this paper, studies of blob properties at the stellarator TJ-K are presented. The generation rate, blob size, and velocity have been studied with Langmuir probes and a fast camera. Special emphasis is put on the influence of the edge turbulence.
