Large Dynamic Range Beam Profile Measurements
Large dynamic range (Peak/Noise >10{sup 5}) beam profile measurements are routinely performed in the Hall-B beamline at Jefferson Lab. These measurements are made with a 1 to 10nA electron beam current with energies between 1 to 6 GeV. The electron beam scatters off of a thin W or Fe wire and the scattered particle/shower is detected via scintillation or Cerenkov light several meters downstream of the wire. This report describes results on increasing the dynamic range by using multiple wires of varying diameters. Profile measurements with this large dynamic range are of use for accelerators with very stored energy (e.g. energy recovering linacs [ERL]) where small beam loss represents a significant amount of beam power. Results on measuring the transverse profile with large dynamic range during the CEBAF energy recovery experiment is also presented.
