Is there nothing in Knoll (Radiation Detect and Measure) that's useful on this subject?  Also, e.g., research-grade NaI crystals are mated directly to the PMT, no?

I looked for something, even qualitative, and could not find anything interesting. I found some stuff related to fiber optics that surprised me (not as big an improvement as I expected), but I do not know how that applies to scintillation detectors. I do not *think* a scintillation detector will work at all without coupling compound.
