	To store high current ion beams up to 10 A, a superconducting storage ring (F8SR) is planned at Frankfurt university. For the realisation, a scaled down experimental setup with normalconducting magnets is being build. Investigations of beam transport in solenoidal and toroidal guiding fields are in progress. At the moment, a new kind of injection system consisting of a solenoidal injection coil and a special vacuum vessel is under development. It is used to inject a hydrogen beam sideways between two toroidal magnets. In parallel operation, a second hydrogen beam is transported through both magnets to represent the circulating beam. In a second stage, an ExB-Kicker will be used as a septum to combine both beams into one. The current status of the experimental setup will be shown. For the design of the experiments, computer simulations using the 3D simulation code bender were performed. Different input parameters were checked to find the optimal injection and transport channel for the experiment. The results will be presented.

MOPL010	ESSnuSB Project to Produce Intense Beams of Neutrinos and Muons	proton, target, linac, injection	207
	E. Bouquerel IPHC, Strasbourg Cedex 2, France
	Funding: This project is now supported by the COST Action CA15139 "Combining forces for a novel European facility for neutrino-antineutrino symmetry-violation discovery" (EuroNuNet). A new project for the production of a very intense neutrino beam has arisen to enable the discovery of a leptonic CP violation. This facility will use the world’s most intense pulsed spallation neutron source, the European Spallation Source (ESS) under construction in Lund. Its linac is expected to be fully operational at 5 MW power by 2023, using 2 GeV protons. In addition to the neutrinos, the ESSnuSB proposed facility will produce a copious number of muons at the same time. These muons could be used by a future Neutrino Factory to study a possible CP violation in the leptonic sector and neutrino cross-sections. They could also be used by a muon collider or a low energy nuSTORM. The layout of such a facility, consisting in the upgrade of the linac, the use of an accumulator ring, a target/horn system and a megaton Water Cherenkov neutrino detector, is presented. The physics potential is also described.

MOPL015	Effect of Beam Losses on Wire Scanner Scintillator Readout, Hypothesis and Preliminary Results	simulation, linac, quadrupole, beam-losses	216
	B. Cheymol ESS, Lund, Sweden
	In hadron accelerators, the characterization of the beam transverse halo can lead to a better understanding of the beam dynamics and ultimately to a reduction of the beam losses. Unfortunately the effect of losses on beam instrumentation implies a reduction of the instrument sensitivity due to the background noise. In this paper, we will discuss the effect of losses on the wire scanner scintillator foreseen for the ESS linac, in particular the different hypothesis for the input will be described and preliminary results will be presented.

MOPL018	Scintillator Detectors for the ESS High Energy Wire Scanner	radiation, simulation, photon, linac	232
	B. Cheymol ESS, Lund, Sweden
	In the ESS linac, during commissioning and restart phase, wire scanner will be used intensively to characterize the transverse beam profiles. At low energy, the mode of detection is based on Secondary Emission (SE), while at energies above 200 MeV, the primary mode of detection will be the measurement of the hadronic shower created in the thin wire. In this paper we will present the design and the output signal estimation of the shower detector, based on inorganic crystal and silicon photodetector.

WEPM8X01	Collimation Design and Beam Loss Detection at FRIB	monitoring, collimation, network, ion	400

	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661. As a multi-charge-state, heavy-ion, superconducting accelerator with a folded geometry, FRIB faces unique beam loss detection and collimation challenges to protect superconducting cavities from beam-induced damage. Collimation is especially important in the Folding Segment 1 where the multiple charge states are created by a charge stripper and selected by a charge selector. The transported ECR contaminants, interaction with the residual gas, and beam halo due to stripping could induced significant beam losses in this region. We have simulated the potential beam losses and planned collimation accordingly. A layered loss detection network is also specifically designed to visualize potential blind zones and to meet the stringent requirements on loss detection. The related sub-systems are designed and procured and are introduced in this paper.

THAM6Y01	Simulations and Detector Technologies for the Beam Loss Monitoring System at the ESS Linac	linac, simulation, DTL, neutron	553
	I. Dolenc Kittelmann, T.J. Shea ESS, Lund, Sweden
	The European Spallation Source (ESS), which is currently under construction, will be a neutron source based on 5 MW, 2 GeV superconducting proton linac. Among other beam instrumentation systems, this high intensity linac requires a Beam Loss Monitoring (BLM) system. An important function of the BLM system is to protect the linac from beam-induced damage by detecting unacceptably high beam loss and promptly inhibiting beam production. In addition to protection functionality, the system is expected to provide the means to monitor the beam losses during all modes of operation with the aim to avoid excessive machine activation. This paper focuses on the plans and recent results of the beam loss studies based on Monte Carlo simulations in order to refine the ESS BLM detector requirements by providing the estimations on expected particle fluxes and their spectra at detector locations. Furthermore, the planned detector technologies for the ESS BLM system will be presented.
