A new 20-channels camera for SXR measurement with a temporal resolution of about 4 microseconds has been designed and is successfully used in the noisy U-3M plasma conditions. In the original electronics design all the diagnostics components, including the STM-32-microporcessor-based data acquisition system, are assembled in a single unit (without analog signals or digital interface wires). This design allows one to prevent the ground loop interference, to remove the RF load on diagnostics components and to increase substantially the system protection from different electromagnetic noises. The diagnostics developed has enabled us to observe different types of the SXR emission fluctuations with frequencies of 70 kHz. Developed SXR diagnostics allow us further studying eigenmodes in fusion plasmas. Product Description popup.authors Єрьомін В.П. Агаркова Н.М. Басаргін В.О. Войценя В.С. Губарєв С.П. . Древаль М.Б.
