The measured pulse currents are displayed locally or remotely as single values or graphs. The data acquisition systems utilize commercial PXI chassis by National Instruments (NI), controllers and 2-channel 14bit, 100MHz high-speed digitizer cards. Measurement routines are programmed with LabVIEW 2012. Special in-house custom made ‘CA-Lab’ client software provides interface for the independent systems to write values into pre-assigned process variables of the EPICS control system. The retrieved data can be displayed in the machine control system and stored in a data archive. This allows shot to shot assessment of the pulse currents for accelerator operation and troubleshooting as well as long term data evaluation in correlation with other relevant machine parameters. This report also describes the set-up for the pulse current measurements and the structured programming for the data acquisition. Limits of the applied measurement technique and experience with the information gained for the accelerator operation will be explained.
