A software framework, called Internal Post Operation Check (IPOC), has been developed to acquire and analyse kicker magnet current waveforms. It was initially aimed at performing the surveillance of LHC beam dumping system (LBDS) extraction and dilution kicker current waveforms and was subsequently also deployed on various other kicker systems at CERN. It has been implemented using the Front-End Software Architecture (FESA) framework, and uses many CERN control services. It provides a common interface to various off-the-shelf digitiser cards, allowing a transparent integration of new digitiser types into the system. The waveform analysis algorithms are provided as external plug-in libraries, leaving their specific implementation to the kicker system experts. The general architecture of the IPOC system is presented in this paper, along with its integration within the control environment at CERN. Some application examples are provided, including the surveillance of the LBDS kicker currents and trigger synchronisation, and a closed-loop configuration to guarantee constant switching characteristics of high voltage thyratron switches.
