We were originally motivated by a desire to determine whether
it is necessary
to model the radiation incident on a package during a halfraum shot or whether the DANTE temperature
can be used directly. This is in the context of using a scale-1
halfraum on the P6-P7 OMEGA axis (qDANTE = 37.4 deg), where the DANTE view
seems similar to that of the witness plate, with the hotspot/wall ratio being roughly the same for
this DANTE view
and the the witness plate view.
This expanded into a more general study of radiation
conditions inside the halfraum, looking, for example at the spatial dependence of
spectral energy distributions. A more
detailed and longer presentation, containing elaborations on some of the slides
presented here as well as aspects of the study not included in this
presentation, is also available:

This longer document represents more of the educational
component of our program, as our undergraduate researchers developed their
understanding of the experiments and modeling tools.
