Sumario: | The ALICE Beam Monitoring System has been developed with the aim of detecting beam failures that can affect the experimental region. It is composed of synthetic diamonds as detector, a material that is particularly adapt to harsh radiation environment. However some sensors have shown an increase in the noise in the last year of operation. For this reason, I have developed a station to study the working parameters of the diamond sensors used in this system, in order to check their conditions. I've found an increase of the dark current of almost all the sensors and, in particular, the sensors of the system BCM-A seem to have suffered a greater damage than the others. |
