In the NSLS-II storage ring during user operation, fast-acquisition (FA) 10-kHz BPM data are collected, and their spectral properties are analyzed. Various periodograms and spectral peaks are being provided every minute, and they are very useful in identifying any changes in the orbit. Unfortunately, because of the large amount of data, only several numbers are being continually archived for later study, and the full raw data are saved only by hand when needed. We are developing methods utilizing tensor decomposition techniques to save and analyze the FA data; this paper reports the current status of this project.
