“Calibration of U400M dee HF-voltage measuring system”

25.05.2018 – FLNR STAD Scientific Seminar “Calibration of U400M dee HF-voltage measuring system”, 11-00, Flerov Lab, b.131, room 250, second floor. 

Speaker: Ivanenko I.A. 

The results of measurement of U400M cyclotron dees absolute voltage using method of bremsstrahlung spectrum measurement for the following resonance system frequencies: 12.8, 13.317, 15.012, 15.1 and 17.5 MHz are presented. 

To get precise bremsstrahlung spectrum maximum energy the bremsstrahlung spectrum was simulated using FLUKA software. Comparison of calculated bremsstrahlung spectrum with the measured one gives maximum energy with an accuracy of ±2 keV. Centre software was used to estimate the effect of dees HF-voltage amplitude on ion beam capture in acceleration.
