New Mineral Oil Attenuation Tester
Index
-
First Light - Data for the following plots were taken
by hand on 2/7/01
with the optics crudely aligned. Automated
data collection and final alignment of optics have occurred since that
date.
-
PMT ratio
with no absorbers - this is the first time that we are able to see
a signal in PMT1 (the one 2 m from the optics) without depending on the
sample cylinder for total internal reflection transport of the light. Singals
in the two PMTs are quite compariable.
-
PMT
ratio with Lucite bar.
