EMuS at CSNS Updated Target Studies

Abstract

In this article, the latest studies of the Experimental Muon Source (EMuS) target systems for muon production and capture are briefly presented. The EMuS is foreseen to be located at the China Spallation Neutron Source (CSNS) in Dongguan. It uses the proton driver of the neutron source and comprises of different target stations and beam lines for muons. EMuS will be a world class muon source especially competitive for muon Spin Resonance (µSR) experiments.

Target Design of MELODY

“…Our studies with FLUKA [7] and G4beamline [8] Monte Carlos show that once the slab is displaced on the horizontal plane or the slab is rotated with respect to the proton beam direction, there is an increase at the rates of surface muons because of the optimized ranges of pions in the target or the increase of the dimensions for the large surfaces of the slab, respectively. Both configurations have been studied also before with similar results in [9], [10] and [11]. Furthermore, other configurations have been studied like doublets, triplets with several rotations, and other surface geometries without being better under our selection criteria.…”
