| Popis: | A new scanning system is considered. The system is developed at JINR and has a number of characteristic features. The windings of the bending magnets with a large number of ampere-turns operate at relatively low frequencies (≤20 Hz) to maintain the reactive power within reasonable limits. The winding power supplies use feedback systems to shape currents of the given waveform and amplitude. The main structural features and parameters of the prototype magnet and the results of developing and testing the electronic circuit for supplying the magnet with a current of the given waveform are presented. Density distributions of various ions on the target are calculated for one of the U400-M cyclotron beam lines using the parameters of the new scanners. |
