Cyclinac Programme PARTNER – UA – 17.10.08 9
Cyclinac = Cyclotron + Linac for Image Guided HadronTherapy RF generators RF generation Fast cycling beam for tumour multi-painting modules computer of LIGHT controlled source (synchro)cyclotron chopped beam at 200-400 Hz PARTNER – UA – 17.10.08 10
Properties of the cyclinac beam Accelerator Beam always Energy variation Time needed for present during by electronic varying the energy treatments means Cyclotron Yes No - 50-100 ms (*) Fast cycling Synchrotron No Yes 1 second The energy is changed by adjusting the Cyclinac Yes Yes 1 millisecond RF pulses to the modules (*) With movable absorbers The cyclinac beam is ideal to paint many times moving tumours in 3D without variable absorbers PARTNER – UA – 17.10.08 11
