	Magnetic channels are used in many cyclotrons to focus the beam radially through crossing of the coils and yoke region. These magnetic channel are generally iron made and use three iron bars to reduce the radial gradient of the cyclotron magnetic field. The current sheet approximation (CSA) was generally used to evaluate their performance. For the new magnetic channel to be used in the upgrading of the k800 cyclotron of the LNS-INFN, we investigate the use of permendur vanadium in alternative to the usual iron to reduce the volume of the bar and mainly the magnetic force. Moreover, using the computer code COMSOL (and CST) the 2D model of the magnetic channels have been optimized using a genetic algorithm and complex geometric configuration. High magnetic gradients with high uniformity and reduced magnetic force were achieved. The preliminary results of our work are presented and discussed.

Magnetic channels are used in many cyclotrons to focus the beam radially through crossing of the coils and yoke region. These magnetic channel are generally iron made and use three iron bars to reduce the radial gradient of the cyclotron magnetic field. The current sheet approximation (CSA) was generally used to evaluate their performance. For the new magnetic channel to be used in the upgrading of the k800 cyclotron of the LNS-INFN, we investigate the use of permendur vanadium in alternative to the usual iron to reduce the volume of the bar and mainly the magnetic force. Moreover, using the computer code COMSOL (and CST) the 2D model of the magnetic channels have been optimized using a genetic algorithm and complex geometric configuration. High magnetic gradients with high uniformity and reduced magnetic force were achieved. The preliminary results of our work are presented and discussed.
