  The existing fast beam current transformers of the LHC have been shown to exhibit both bunch length and bunch position dependency. A new Integrating Current Transformer (ICT) have therefore been developed in collaboration with Bergoz Instrumentation to address these issues. As goals a 0.1 %/mm beam position dependency and 0.1 % bunch length dependency were specified, along with a bandwidth of 100 MHz. This paper describes the principles of ICT operation and presents the laboratory measurement results obtained with the first prototypes at CERN.
