Description:

(abstract)

In order to secure the sample to the sample holder and create a structure that serves as a partition between the gas introduction system on the back of the sample and the ultra-high vacuum measurement chamber, a vacuum seal must be completed at the same time as the sample is fixed. We searched and tried sealing methods to perform permeation measurements on samples with several mm size, since standardized products such as international ConFlat flanges cannot be used for vacuum seals in these sizes.
