The prototype of uniquely designed complex data acquisition system for ITER divertor Thomson scattering diagnostic was developed. It allows recording short duration (3-5 ns) scattered pulses with 2 GHz sampling rate and 10-bit total resolution in oscilloscope mode. The system consists of 48 photo detector modules with 0-200 MHz bandwidth, 48 simultaneously sampling ADC modules and synchronization subsystem. The photo detector modules are based on avalanche photodiodes (APD) and ultra-low noise transimpedance amplifiers. ADC modules include fast analog to digital convertors and digital units based on the FPGA (Field-Programmable Gate Array) for data processing and storage. The synchronization subsystem is used to form triggering pulses and to organize the simultaneously mode of ADC modules operation.
