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...
Uniquely designed complex data acquisition system for Thomson scattering diagnostic was developed. It allows recording short duration (3–5 ns) scattered pulses with 2GHz sampling rate and 10-bit total resolution in oscilloscope mode. The system consists up to 48 photo detector modules with 0200MHz bandwidth, 1–48 simultaneously sampling ADC modules and synchronization subsystem. The photo detector...
Thomson scattering diagnostic is the most reliable and widely used method to measure electron temperature and density profiles of magnetically confined plasma. The prototype of data acquisition system for ITER divertor zone Thomson scattering diagnostic has been recently developed at the Budker Institute of Nuclear Physics (Novosibirsk, Russia). The small power (∼10−8W) and short duration (∼3–5 ns)...
The data acquisition system was developed for the diagnosis of Thomson scattering systems on GOL-3 and GDT. It's include: the modules photodetectors based on the avalanche photodiodes, working in real-time mode recorder based on 12 bit 500 MSPS ADC, the synchronization system providing synchronous operation of the multiple channels of the recording system and the communication modules for the interfacing...
The real-time processing of the electron beam parameters is a necessary procedure to optimize the key characteristics of the synchrotron radiation source. To study multi-bunch beam instabilities a high-speed electron beam profile monitor is developed. The device described must continuously implement 15625000 measurements of the vertical or horizontal electron beam profile at 16 points with a time...
