Classification: CPC G | IPC G

Claim 0:
1. A particle beam dose profile measurement apparatus comprising:
a particle detector stack comprising a plurality of scintillator layers, wherein:
each scintillator layer of the detector stack is disposed along an axis of the apparatus such that the axis projects through each layer; and
each scintillator layer is configured to produce scintillation light indicative of an energy deposition, in that scintillator, of a particle beam incident upon the detector stack along said axis,

readout circuitry configured to measure the scintillation light of each scintillator layer; and
dose profile determination circuitry configured to determine a dose profile of said particle beam within the detector stack, said determination is based on:
fitting a theoretical energy deposition profile to the measured scintillation light of each scintillator layer,
wherein said theoretical energy deposition profile comprises a quenching correction.
