Characterization of the new MCP-PMT as a timing detector for beta particles

Recently we received our new MCP-PMT of which I presented a first test in this post. Today I am posting the first serious characterization of the device. All the details can be found in this document which I embed below:

As a summary, I measured a time resolution of about 22-24 ps for the MCP-PMT as a beta particle time tagger.
