We have developed a data acquisition and analysis program for the PEEM station at NSRRC. This program system can handle several gigabytes of data flow generated by the newly commissioned PEEM station. The data acquisition system controls one CCD, five gratings, several Pico-am current meters, and the PEEM system through one PC computer. A multi-threaded programming technique is used in this system to manage all the hardware components systematically in the timing domain while recording the image data. The image data consists of individual energy spectrum for each of the 1035 x 1317 pixels of the CCD. By comparing the spectra with those stored in the database, we can identify, with a score of likelihood, the elements and their oxidation states in the sample system. An FET device composed of three different materials, Silicide, silicon oxide, and silicon, has been used to test the performance of the program system. The results are consistent with those obtained by the SPEM station.
