Transmission electron microscopy in plasma surface interaction in fusion research.

Transmission electron microscopy (TEM) is a powerful method to study the microstructure of plasma facing materials in fusion devices. The main topics that have been presented so far are the observation of radiation damage caused by particle bombardment and the characterization of deposits and dust created in fusion devices and transient heat load events. The present work summarizes the recent TEM works in this field and the possible use of TEM studies in high heat flux testing.
