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, 100 mA proton accelerator. The concept intends to optimize the facility such that it provides high-brilliance neutron beams for instruments operating at different time structures. This can be realized by three different target stations irradiated with different 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. *

“…To achieve the final beam energy of 70 MeV, the HBS Linac consists of a front end (ECR source), low energy beam transfer (LEBT, 2.5 MeV double radio frequency The beam is sent to three different targets by means of a multiplexer in the high energy beam transfer (HEBT) [4]. Hereby, a geometric request to the deflection angle from the particle orbit comes from the dynamics of the ion beam in the setup.…”
