Proton Beam Multiplexer Developments for Multi-Target Operation at the High-Brilliance Neutron Source HBS

Abstract

The High-Brilliance neutron Source project (HBS) aims at developing a medium-flux acceleratordriven neutron source based on a 70 MeV, 100mA proton accelerator. The concept intends to optimize the facility such that it provides high-brilliance neutron beams for instruments operating at di_erent time structures. This can be realized by three di_erent target stations irradiated with di_erent proton pulse sequences. The appropriate proton pulses will be distributed by a Multiplexer unit. In the following, we present the integration of this Multiplexer with the HBS beam optics as well as ongoing developments of this unit and several components of the Multiplexer at the COSY facility in Jülich.
