The Methodology and Results of Absolute Dee Voltage Measurements at the Cyclotrons of the FLNR JINR Using the X-Ray Spectrum Method

— The methodology and results of absolute dee voltage measurements using the X-ray spectrum method at the FLNR JINR cyclotrons are presented. An Amptek XR-100T-CdTe semiconductor detector was used to measure bremsstrahlung spectra. The technique was tested on the U-400M isochronous cyclotron and was used to adjust the high-frequency accelerating system to the operating mode during commissioning of the DC-280 cyclotron.
