Pohang Accelerator Laboratory (PAL) built a PAL-ITF (Injector Test Facility) at the end of 2012 to successfully complete PAL-XFEL (X-ray Free Electron Laser) in 2015. The PAL-ITF is equipped with various kinds of diagnostic equipment to produce high-quality electron bunches. The three main parameters that an injection testing facility should measure are charge, energy and emittance. Although ICT and Faraday Cup were installed to measure beam charge, the noise generated in a klystron modulator not only interrupted accurate measurement but prevented low charges under tens of pC from being measured. Due to the changes in the overall voltage level of ITF, integration of ICT measured value failed to maintain perfect accuracy in terms of methodology (measured value continuously changed by ± 5pC). Accordingly, to solve the noise problems and accurately measure the quantity of electron beam charge, Turbo-ICT was installed. This paper focuses on the processes and test result of electric bunch charge quantity measurements using Turbo-ICT.
