[Dsg-rich] all data for RICH prototype mirror reflectivity test

[Tyler Lemon]

Hello,

Attached are the raw data for the tests performed on the prototype mirror. Each Excel file is from tests one spot of the mirror. Within each Excel file are several sheets: compiled results based on the average of measurements, calibration data for Photodiode A and B (these sheets are the same for all measurements taken on the same day) and measurement data for Photodiode A and B. In the event that the attached zip file is too large to send correctly, the data have also been posted at https://userweb.jlab.org/~tlemon/RICH/2020-01_RICH_prototype_mirror/

For each spot, the LabVIEW program took 25 measurements of each photodiode in the test station.

To provide more background on the test station and how it works, below are some links to previous DSG notes and talks on the tests for the previous RICH sector. If there are any questions, please let us know.

To the collaborators who fabricated the mirror, thank you very much for the acknowledgement and discussion on the mirrors that was forwarded to us by Dr. Rossi.

If there are any other mirrors fabricated that you would like tested, DSG would gladly measure those mirrors as well. We look forward to helping you refine the mirror fabrication process.

Best regards,
Tyler
