fiber emission spectra - status report

[Alex Dzierba <dzierba@indiana.edu>]

Hi All

Blake has recently made measurements of emission spectra
for 2-m samples of blue (BCF-12), fast-green (BCF-20) and
slow-green (BCF-60) fibers for the source (LED) at various
distances from the end of the fiber attached to the
spectrophotometer.  The spectra were fit to Moyal functions,
integrated over wavelength and preliminary attenuation lengths
were found.  See preliminary results here:

This is a work in progress - more will be done by including the
spectra from manufacturer's to estimate the spectra
at "zero cm"  (similar to the analysis described in
GlueX-doc-924)

Cheers
Alex
