light loss in blue fibers



Dear All

Following a conversation with George and Elton yesterday, I did a
crude estimate of the light loss in the BCAL fibers used for the
beam test using information from spec sheets from Bicron and
Kuraray (Elton posted these on the portal).  The Regina
group is doing a more refined calculation based on their detailed
measurements of emission spectra at various source distances from
a UV source exciting the fiber.

Cheers
Alex
