2.1.5 Bulk Metals

Three metallic surfaces were investigated as conversion surface.

The tungsten surface served as a performance test and as reference for the ILENA apparatus and was also used used as a neutralization surface in the NICE setup where mainly angular scattering was of interest. The tantalum foil was tested because of its availability (all the mounting parts for the surface were made of tantalum). To compare the results with tungsten single crystals a tantalum single crystal was investigated.
