Betsy, Travis, Gabriele

This afternoon Gabriele was kind enough to help us take the in-air violin measurements on the ETMXQUAD sus.  We set up all of the in-chamber equipment (HeNe laser/QPD setup) and adjusted them to sight across one fiber at a time, while Gabriele ran the spectrum analyzer.  

We were able to obtain data from the first 3 harmonics of the v-modes on 2 of the fibers (took about 2 hours).  Tomorrow we will proceed with the other 2 fibers.  More to come...
