Animated pictures of the Hamamatsu R15458-02 PMT performance under different magnetic field orientations

The Hamamatsu R15458-02 PMT's photocathode was scanned with a collimated beam at 777 different positions to determine the relative transit time and gain. This measurement was performed at 192 different magnetic field orientations with a strength of 54.7 microtesla. These slides present measurement results as animated GIFs. Currently, PowerPoint and Google Slides display the images correctly, but LibreOffice does not. For further details, you can refer to Chapter 7 of M. Unland thesis "Development, simulation, and characterisation of a novel multi-PMT optical module for IceCube Upgrade with emphasis on detailed understanding of photomultiplier performance parameters" published in 2023
