Characterization of LR-115 as an SSNTD
Okay, I have some LR-115, in 9x12 cm pieces. I intend to cut it up into 1 cm squares for actual use, though I might make them a little bigger, to allow for one or two indexing holes. First of all, there is a lot of information on LR-115 out there, but behind pay walls. I don't have library access. What information is available on the response of LR-115 to proton radiation in the range up to, say, 4 to 6 MeV? How does development time affect this response?
The single test I have done so far with LR-115 leads me to think that I may be able to control the response by controlling the etching time or temperature. (Images may be viewed at ; one will first have to join the yahoogroups list (using the web interface, and with cookies enabled) to be able to see the images.)
I have an Am-241 source ripped out of a smoke detector. That's what I used for my first LR-115 test. But this is an alpha source, and the response of the material to protons is likely to be quite different. I do know that the material is sold to be used for neutron detection through proton knock-on. See  for a data sheet on LR-115. (I have Type I film, with a 6 micro detector layer.)
So, first of all, can any participant here find information on the response from the literature?
Second, does anyone have access to exposure to neutrons? (I could put together a detector package, mounted on a piece of acrylic cell wall, so it would match the configuration as I plan to use the stuff in the actual experimental runs.) Or access to exposure to protons of known energy in the MeV range?
