Due to the decommissioning of several research reactors there will be a severe drop in available neutrons for research in Europe in the next decade despite the commissioning of the European Spallation Source (ESS). The High Brilliance Neutron Source (HBS) currently under development at Forschungszentrum Jülich is scalable in terms of beam energy and power due to its modular design. The driver Linac for HBS at will accelerate a 100 mA proton beam to 70 MeV. The Linac is operated with a beam duty cycle of up to 6% (11% RF duty cycle) and can simultaneously deliver three proton pulse lengths (384 Hz at 52 µ s, 96 Hz at 208 µ s and 24 Hz at 832 µ s) for three neutron production targets. The front end of the HBS Linac consists of an ECR source, LEBT and a 2.5 MeV RFQ followed by a CH-DTL with 35 room temperature CH-cavities. The presentation describes the conceptual design and the challenges of such a modern high power proton accelerator with high reliability and availability.
