A systematic cross-machine study has been initiated to investigate the remobilization of tungsten micron-size dust from tungsten surfaces implementing a newly developed technique based on controlled pre-adhesion by gas dynamics methods. It has been utilized in a number of devices and has provided new insights on remobilization under steady-state and transient conditions. The experiments are interpreted with contact mechanics theory and heat conduction models. }, year = {2017}, journal = {Nuclear Materials and Energy}, volume = {12}, pages = {569-574}, month = {08/2017}, doi = {10.1016/j.nme.2016.10.021}, language = {eng}, }
