Gigahertz (GHz) hard x-ray imaging using fast scintillators


Gigahertz (GHz) imaging technology will be needed at high-luminosity X-ray and charged particle sources. It is plausible to combine fast scintillators with the latest picosecond detectors and GHz electronics for multi-frame hard Xray imaging and achieve an inter-frame time of less than 10 ns. The time responses and light yield of LYSO, LaBr_3, BaF_2 and ZnO are measured using an MCP-PMT detector. Zinc Oxide (ZnO) is an attractive material for fast hard X-ray imaging based on GEANT4 simulations and previous studies, but the measured light yield from the samples is much lower than expected.

The DRS4 board was developed by Stefan Ritt (stefan.ritt@psi.ch) of Paul Scherrer Institute. The proton measurements were performed at the Los Alamos proton radiography (pRad) facility with the help from the pRad team. LLNL funded the MIT-LL CMOS prototype imager work.
