Profile Measurement Of Scanning Proton Beam For LiSoR Using Carbon Fibre Harps

Harps using secondary electron emission from 16 carbon monofilament wires have been built to measure the horizontal and vertical beam profiles of an intense 71 MeV proton beam. A very large dynamic range and good time resolution are achieved by a newly developed 16 channel CAMAC read‐out module using logarithmic amplifiers. A first test at low beam current is reported.
