Large energy acceptance gantry for proton therapy utilizing superconducting technology.

We describe the iterative process we have applied to design the magnets and the beam transport, for which we have used different codes. <i>COSY Infinity</i> and <i>OPAL</i> have been used to design the beam transport optics and to track the particles in the magnetic fields, which are produced by the magnets designed in <i>Opera</i>. With beam optics calculations we have derived an optimal achromatic beam transport with the large momentum acceptance of the proton pencil beam and we show the agreement with particle tracking calculations in the 3D magnetic field map.
 
 A new cyclotron based facility with this gantry will have a significantly smaller footprint, since one can refrain from the standard degrader and energy selection system behind the cyclotron. In the treatments, this gantry will enable a very fast proton beam delivery sequence, which may be of advantage for treatments in moving tissue.&#13.
