	At GSI ion beams of many elements, from H up to U, are produced with energy as high as 4.5 GeV/u with the SIS-18 synchrotron. For absolute beam intensity and micro-spill structure measurements a BC400 organic scintillator is used. Due to the low radiation hardness of this material, alternative inorganic scintillators like ZnO:Ga and ZnO:In were investigated. The properties and possible application of these novel radiation hard fast scintillators will be discussed. Their response to Sn, Xe and U ion beams will be reported.

MOPP006	Commissioning of the Beam Loss Monitoring system for the HADES beam-line at GSI	74
	P. Boutachkov, S. Damjanovic, M. Sapinski, B. Walasek-Höhne GSI, Darmstadt, Germany
	The High Acceptance Di-Electron Spectrometer experiments at GSI (HADES) require high-intensity heavy ion beams. Monitoring and minimization of the beam losses are critical for the operation at the desired beam intensities. FAIR-type Beam Loss Monitor (BLM) system based on sixteen plastic scintillator detectors is installed along the beam line from the SIS-18 synchrotron to the experiment location. The detectors are used in counting mode, with maximum counting rate of order of 20 MHz. The system has been commissioned during the 2018 beam time. Details on the detector setup, its calibration procedure and how it can be used for quantitative beam loss determination are presented.

MOPP037	Status of Beam Instrumentation for FAIR HEBT	193
	M. Schwickert, P. Boutachkov, T. Hoffmann, H. Reeg, A. Reiter, B. Walasek-Höhne GSI, Darmstadt, Germany
	At present the Facility for Antiproton and Ion Research (FAIR) is under construction at the GSI site. As part of the FAIR project the beamlines of the High Energy Beam Transport (HEBT) section interconnect the synchrotrons, storage rings and experimental caves. The large range of beam energies (MeV to GeV) and beam intensities up to 10¹² particles per pulse for uranium, or up to 2·10¹³ particles per pulse for protons, demand in many cases for purpose-built beam diagnostic devices. Presently, the main diagnostic components are being manufactured by international in-kind partners in close collaboration with GSI. This contribution presents an overview of the beam instrumentation layout of the FAIR HEBT and summa-rizes the present status of developments for HEBT beam diagnostics. We focus on the status of the foreseen beam current transformers, particle detectors, scintillating screens and profile grids.

	Funding: This project has received funding from the European Union¿s Horizon 2020 programme under Grant Agreement No 730871. Scintillation screens made of various inorganic materials are widely used for transverse beam profile diagnostics at all kinds of accelerators. The monitor principle is based on the particles¿ energy loss and its conversion to visible light. The resulting light spot is a direct image of the two-dimensional beam distribution. For large beam sizes standard optical techniques can be applied, while for small beam sizes dedicated optical arrangements have to be used to prevent for image deformations. In the modern linac based light sources scintillator usage serves as an alternative way to overcome limitations related to coherent OTR emission. Radiation damages and intensity based saturation effects, in dependence of the screen material, have to be modelled.
