The Spallation Neutron Source (SNS) injection and extraction kicker systems were designed by Brookhaven National Laboratory for SNS. The kicker control system is integrated using EPICS and has been used for supporting SNS ring commissioning and now for SNS beam production operations. One of the major challenges for SNS operations is to control beam loss. SNS Injection and Extraction Kicker Waveform monitor system has been implemented to support SNS high power operation. In this paper we present a method for kicker power supply waveform monitor system by using current industrial technology and recent operation experiences.
