  The China Spallation Neutron Source¿CSNS¿accelerator comprises an 80MeV linac and a 1.6GeV rapid cycling synchrotron. It started operation in 2018, and the beam power delivered to the target has increased from 20kW to 140kW, step by step. Various beam loss studies have been performed through the accelerator to improve the beam power and availability. For the CSNS linac, the primary source of the beam loss is the halo generated by beam mismatches. In the upgrade plan of the CSNS, the beam current will increase five times, which requires more strict beam loss control. Much work is done during the design phase to keep the loss down to 1W/m of loss limit. This paper will report results obtained from beam experiments and optimization methods applied to the CSNS linac upgrade design.

  IMPACT (Isotope and Muon Production with Advanced Cyclotron and Target Technology) is a proposed upgrade project for the high-intensity proton accelerator facility (HIPA) at the Paul Scherrer Institute (PSI). As part of IMPACT, a new radioisotope target station, TATTOOS (Targeted Alpha Tumour Therapy and Other Oncological Solutions) will allow to produce promising radionuclides for diagnosis and therapy of cancer in doses sufficient for clinical studies. The proposed TATTOOS beamline and target will be located near the UCN (Ultra Cold Neutron source) target area, branching off from the main UCN beamline. In particular, the 590 MeV proton beamline is intended to operate at a beam intensity of 100 uA (60 kW), requiring a continuous splitting of the main beam via an electrostatic splitter. Beam loss simulations to verify safe operation have been performed and optimised using BDSIM, a Geant4 based tool enabling the simulation of beam transportation through magnets and particle passage through accelerator. In this study, beam profiles, beam transmission and power deposits are generated and studied. Finally, a quantitative description of the beam halo is introduced.
