MOP065	Consolidated Design of the 17 MeV Injector for MYRRHA	274

	Funding: Project supported by the EU, FP7 MAX, contract No. 269565 and BMBF, contract No. 06FY7102. The MYRRHA research reactor will be an Accelerator Driven System, which demands a 2.4 MW proton beam delivered by a 600 MeV cw operated linac. The beam dynamics design of the injector has been consolidated to fulfil the requirements with respect to beam losses and quality. After a 4-rod-RFQ, four 7-gap room temperature CH cavities with a constant phase and an effective voltage of 750 keV are used to reach 4.3 MeV. Then the proton beam is accelerated to 18 MeV using six superconducting 5-gap Nb CH structures with a constant beta profile. With reducing the gradient and adjusting the phase of the twelfth CH structure the originally demanded 17 MeV can be delivered, too. Every SC CH cavity is cooled down to 2K with liquid helium in a separate cryo module. The new geometric design of the SC CH cavities improves the rigidity and reduces the electric peak field.
