Fast data acquisition measurement system for plasma diagnostics using GEM detectors

This paper refers to measurement system for plasma diagnostics for tokamaks currently being developed. For the most of the GEM detector readout structures, large number of input channels is required to form a working measurement system. This constraint is especially important for two-dimensional GEM readout structures. Presented measurement system layout is a general model for further implementation. The system is based on fast serial gigabit links and PCI-Express interface for communication. The system can support up to 512 measurement channels, per each PCI-Express x16 slot. The system consists of several modules – PCI-Express 8-to-1 switch, Analog Front End, ADC Front End, and FPGA backplane boards. Implemented data processing algorithms enable fast raw data acquisition and real-time processing. The integration algorithms allow measurement system to cooperate with GEM detector working at high rates.
