Description
High-repetition-rate, multi-petawatt laser systems require high-throughput diagnostics capable of capturing proton beam characteristics on a shot-to-shot basis. We present GOSSIP (Glowing On-shot Scintillator Stack for Imaging Protons), a compact, reusable, multi-layer scintillator diagnostic designed to measure spatially resolved transverse proton beam profiles across multiple energies. The diagnostic has been deployed in multiple experiments, including proton beam profiling and proton probing measurements of field dynamics at the NSF ZEUS facility. Results demonstrate the ability to resolve fine beam features and capture energy-dependent spatial structure. We will also discuss key technical challenges, including scintillator material optimization, calibration requirements, and resolution limits due to scattering. GOSSIP provides a scalable approach for real-time proton beam diagnostics in next-generation high-intensity laser experiments.
