| Sumario: | The LHCb preshower is a scintillator plane preceded by a lead sheet of 2.5radiation lengths. Its main task is to validate the electromagnetic nature of the showers for the Level 0 trigger. The readout system, working at the LHC frequency, has a large dynamics, high accuracy and allows successive triggers. It includes 64 anode photomultiplier tubes, an analogue very front end board and a digital front end board. The full readout system will be described in the following. |
