>Well, I hear KODAK has the widest spectral sensitivity to INFR_RED, Konica
has a little less detection range, and so forth. Although I recently had
the idea, after speaking with people on hypersensitization, if you hyper
infra-red film, you make it like 2-3 stops faster, but still retain the
infra-red response curve..
>Look in astronomy magazines for companies advertiseing hypersensitization
equipment, usually involves hydrogen gas pressure, etc. as I understand.

This may not increase overall speed as much as you think. the purpose
behind hypering is to drive out moisture in the film that causes the
electron charge from low exposure levels from leaking away, ie overcoming
reciprocity failure. It may be worth the try anyway
