2.1.2 Magnesium Oxide and Aluminum Oxide Surfaces

Different MgO based surfaces were tested to be used as the stop surface:

All these samples had a usable surface area of 1 to 2 cm\( ^{2}\). The following surface was tested for use as a conversion surface:

This conversion surface had a size of 10mm x 10mm. The remaining surface roughness was typically of the order of 1nm\( _{rms} \) as specified by the supplier [7].
