Stulle, F. Bergoz, J.F. MOP041 resonance impedance laser plasma network 2015 2015-12 We report on the calibration methods implemented for the Turbo-ICT/BCM-RF. They allow to achieve percent-level accuracy for charge and current measurements. Starting from the Turbo-ICT/BCM-RF working principle, we discuss scientific fundaments of calibration and their practical implementation in a test bench. Limits, both principle and practical, are reviewed. Achievable accuracy is estimated.
