The test set-up of Electron Linac Low-level RF system

During the commissioning of RF power supply systems for electron accelerators developed by the SINP MSU and built on the basis of KIU-168, KIU-271 klystrons, there is a need to check and calibrate the low-level RF system, which generates the input signal of the klystron in the form of a rectangular pulse of adjustable duty cycle, filled with high-frequency oscillations. The task of calibrating the low-level RF system is to obtain the dependence of the output pulse power on the control voltage of the variable attenuator in the form of a graph and a table. For this purpose, a test set-up was built. Then the calibration process was automated using Matlab-based software.
