In January 2019, the UConn group opened up the tagger microscope and replaced the 7 fiber bundles subtending columns 1-42 with new ones that have been fabricated at UConn over the past year. These new bundles were constructed using St Gobain double-clad fibers in place of the single-clad light guide material that was used for the fibers that were originally installed. This upgrade completes a 3-year process of completely replacing the original defective fibers with new ones. In addition to using the improved light guide material, these replacement fibers were fused and bent using updated procedures that greatly improved the consistency of the results. This talk shows the performance of the detector in the GlueX tagger focal plane following the upgrade.
