For the LHCb detector at the Large Hadron Collider, the ongoing second long shutdown (LS2) of CERN's accelerator complex will be a period of metamorphosis. After two successful data-collection runs, the detector is being upgraded to improve the precision of its physics measurements, many of which are the best in the world. There will therefore be five times more collisions every time proton bunches cross within the detector after LS2 and the LHCb collaboration plans on increasing the data-readout rate from 1 megaHertz to the LHC's maximum interaction frequency of 40 megaHertz (or every 25 nanoseconds).
