Description
The high luminosity upgrade of the LHC will result in an average pile-up of about 200 interactions per bunch crossing.
The time information of the particles measured by the detectors can be used to mitigate the effects of pile-up on the reconstructed data.
Several groups are investigating different technologies to achieve a sufficient time resolution for this goal.
The Picosec group of the CERN RD51 collaboration is developing gas detectors with high time resolution.
A beam test was carried out in October 2016 to characterize the time performance of different gaseous and solid state detectors.
The focus of this talk is the characterization of the Micro Channel Plate photomultiplier (MCP-PMT) used as time reference in the beam test.
A special run with two MCP-PMTs and oscilloscope readout is used to characterize their time performance.
The time resolution of the MPC-PMTs is studied using different algorithms.
The influence of different effects on the time resolution of the system is investigated.
