Query: A Factor of Four Increase in Attenuation Length of Dipped Lightguides
  for Liquid Argon TPCs Through Improved Coating   This paper describes new techniques for producing lightguides for detection
of scintillation light in liquid argon time projection chambers. These can be
used in future neutrino experiments such as SBND and DUNE. These new results
build on a dipped-coating technique that was previously reported and is
reviewed here. The improvements to the approach indicate a factor of four
improvement in attenuation length of the lightguides compared to past studies.
The measured attenuation lengths, which are >2 m, are consistent with the bulk
attenuation length of the material. Schematics for a mechanical dipping system
are provided in this paper. This system is shown to result in coatings with <
10% variations
