Description

The U400M cyclotron complex has been operating at FLNR JINR since 1992. Since 2020, it has been undergoing modernization, which includes the reconstruction of the RF power supply system for the cyclotron accelerating system.

Reconstruction of the RF power system includes:

• replacement of the old rigid coaxial line with a modern design;

• calculation and manufacture of higher harmonics filter;

• calculation and manufacture of a device for matching the rigid
  coaxialline with a resonant system;

• calculation and manufacture of a capacitive trimmer for automatic
  frequency adjustment of the resonant system;

• calculation and replacement of an interstage broadband matching
  device.

The paper presents the results of calculations and the results of measurements of the finished elements of the system.
