Abstract
With the advent of LHCb Upgrade II new technologies in detection are required to keep up with the increased luminosity. One of the technologies developed are new Photomultiplier Tubes (PMTs), capable of amplifying the received signal. These new PMTs must have a time resolution below 50 ps. In this end of degree project I characterised two PMTs manufactured by Hamamatsu, the R11187 and the R14755U-100. The characterisation consisted in measurements of time resolution in both devices and a gain measurement in the first one. The values obtained for the time resolution are below the threshold of 50 ps and the gain (G = 7 × 105) is compatible with the requirements for the detector.
