However, at that time, there is still no consensus in the linac community on the best
radiofrequency (RF) structures to use in the intermediate section (from 5 MeV to 100 MeV).
There is some debate still open concerning the best structure to choose. This is why many
different options are still open including a "warm option" (i.e. room temperature RF
structure) and two superconducting options (crossbar and spoke cavity). Advantages and
disadvantages of these different structure types can be compared, especially regarding the
XADS specific requirements (reliability and tuning). But it is clear at this point that no definite
solution will be firmly given for this intermediate section until some particular R&D has been
finalized, laboratory performance demonstrated and a thorough comparison performed.
Figure 3.2-12 illustrates the linac scheme.
