	Time-resolved temperature mapping of a superconducting cavity can give valuable information on the limiting process of the cavity performance. A fast temperature mapping system has been developed at Argonne National Laboratory (ANL) for a superconducting deflecting cavity test. The time resolution of the temperature mapping could be up to 50 us. Not only the spatial distribution of surface heating but also the thermodynamics can be recorded, which helps to understand the limitation mechanism. This new temperature mapping system has helped us to understand the rf performance limitations during the cavity vertical tests. Based on the findings from the temperature mapping, proper cavity treatment has been applied and the cavity performances have been improved.
