The characterization of the 780 nm optical filter was performed in the UITF laser room using a SuperK Fianium source equipped with an LLTF Contrast filter to provide tunable wavelengths. Measurements were taken with the optical filter oriented in both directions, allowing the laser to be incident on each face of the filter. In addition, the laser power was measured without the optical filter in the beam path, and these values were used to normalize the transmitted power measured through the filter.

Had to lower gradient from 12 Mv/m to 6 Mv/m due to CWWT trips 20 minutes after recovering to 12 Mv/m. Changed ODVH to 6Mv/m until we see if it will stay on after klystron replaced today.
