Libera Spark HR
Libera Spark is a compact beam position processor that offers high-precision position measurement of different beam types (electrons, protons, ions, etc.). It is optimized to work with button, stripline and shoe-box pickups. The digital signal processing (DSP) supports detailed adjustment of the processing window and position measurement in various regimes and bandwidths. Depending on the requirements and the Libera Spark version, the data available to the user ranges from bunch-to-bunch, turn-by-turn to slow data stream.
