In this work the shock-to-detonation transition of Hexanitrostilbene (HNS-II) is investigated in a modified 21mm PMMA gap test. Time of Arrival (ToA) measurements determine the run-to-detonation distance (RDD) of the specimen. Combined with the calibrated donor/gap system this results in a Pop plot which is compared to numerical results and used to calibrate a reactive burn model.enHNSrun-to-detonationgap testpop plottime of arrivalposter
