Challenges in continuous profile monitoring include degradation of materials after long-term exposure to the proton beam, as well as beam loss due to that material intercepting the beam, which can additionally cause activation of nearby equipment. An overview of various profile monitoring techniques used in high-power neutrino extraction beamlines, issues faced so far at beam powers up to several hundred kW, and some possible future profile monitoring solutions for MW-class beamlines will be shown.
