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.

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.

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.
