# Étude et développement d'un dispositif non-interceptif de mesure d’intensité du faisceau du GANIL de haute résolution ($<$1nA) et de haute précision ($<$1)

Abstract : The GANIL beam intensity measurement System enables tuning and control of the accelerator system. All along the ion beam transport line, the intensity is measured continuously with low frequency current transformers. The performance as optimized today is not satisfactory to precisely determine the accelerator efficiency on-line. A first study showed that the only sensors usable at GANIL are sensors sensitive to magnetic field (current transformers) and to electric field (capacitive probes). The theoretical study searched to predict the output of these types of sensors and enabled to define a signal treatment which corresponds to the specifications. For every sensor, this calculation is validated experimentally. Moreover this study raised the problem of calibration. The different tests completed allowed a definition of the real characteristics of the current measurements and a choice of the appropriate system.
