This contribution summarizes the design and performance test of a prototype radiation-hard fast scintillation detector based on the indium-doped zinc oxide ceramic scintillator, ZnO(In). The prototype detector has been developed for use as a beam diagnostics tool for high-energy beam lines of the SIS18 synchrotron at the GSI Helmholtz Center for Heavy Ion Research GmbH. The new detector consists of multiple ZnO(In) scintillating ceramics tiles stacked on the front and back sides of a borosilicate light guide. The performance of the detector was tested in comparison to a standard plastic scintillation detector with 300 MeV/u energy 40Ar, 197Au, 208Pb, and 238U ion beams. The investigated prototype exhibits 100% counting efficiency and radiation hardness of a few orders of magnitude higher than the standard plastic scintillation counter. Therefore, it provides an improved beam diagnostics tool for relativistic heavy-ion beam measurements.

We report on the status of work on a non-invasive profile monitor under development for use at the Facility for Rare Isotope Beams (FRIB), a heavy-ion LINAC which produces high-intensity, multi-charge state beams. The measurement will be made by collecting photons generated at the interaction point of the beam and a collimated molecular gas curtain. These photons will be collected with an intensified camera system, generating a two dimensional image and allowing for measurements of profile, beam halo, and other properties more prevalent at specific locations of interest, such as charge state spread after folding segment bends. Included will be ongoing design specifications, simulation results, and discussion of measurement techniques for acquiring signal from the device.
