Measuring deuterium permeation through tungsten near room temperature under plasma loading using a getter layer and ion-beam based detection
A method to measure deuterium permeation through tungsten near room temperature under plasma loading cardboard sweet stand is presented.The permeating deuterium is accumulated in a getter layer of zirconium, titanium or erbium, respectively, on the unexposed side of the sample.Subsequently, the amount of deuterium in the getter is measured ex-situ
