Abstract (en)

[origin: US4639634A] Cyclotron permitting a better utilization of the power when an internal target is used. According to the invention, vertical defocussing coils are arranged along a circular path across which is arranged the target. The elongated, curved coils have the effect of destroying the vertical focusing and consequently widen the beam before impact takes place with the target, so that the latter is not damaged. Application to the production of radioisotopes.
