Description

The High Brilliance Neutron Source (HBS) is a new High Current Accelerator-driven Neutron Source (HiCANS) project, planned and to be realized at the Forschungszentrum Jülich, Germany.
The project represents a promising alternative for expanding neutron availability in Europe by using a high-current, low-energy proton accelerator and state-of-the-art technologies to deliver thermal neutron fluxes comparable to medium to high flux reactor sources, supporting both scientific and industrial applications.
The driver accelerator is designed to reliably accelerate a 100 mA proton beam to 70 MeV, which will then be distributed pulse-by-pulse via a multiplexer to three different neutron targets, each operating with a distinct time structure.
The planned linear accelerator (LINAC) consists of an ECR source, a LEBT section, two RFQs, and more than 45 normal-conducting CH drift tube structures.
This talk will present the layout of the proposed normal-conducting HBS accelerator, with a particular focus on the challenges in the design of the resonators and the beam dynamics of the CH drift tube section.
