| Abstract |
Proton beam monitoring is essential for the J-PARC neutrino beamline, where neutrinos are produced by the collision of 30 GeV protons with a long carbon target. Along with continued upgrades to the J-PARC beam power, from the current 420 kW to 1.3+ MW, there is also a requirement for monitor upgrades. A Beam Induced Fluorescence monitor is under development, which would continuously and non-destructively measure the proton beam profile spill-by-spill by measuring fluorescence light from proton interactions with gas injected into the beamline. Monitor design is constrained by the J-PARC neutrino beamline configuration, where a major challenge will be getting sufficient signal to precisely reconstruct the proton beam profile. R&D for a pulsed gas injection system is under way, where injected gas uniformity and vacuum pump lifetime are main concerns. Design of a light detection system is also under way, where light transport away from the high radiation environment near the proton beamline, as well as fast detection down to very low light levels, are essential.
