R. Anne et al., A NONINTERCEPTIVE HEAVY-ION BEAM PROFILE MONITOR BASED ON RESIDUAL-GAS IONIZATION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 329(1-2), 1993, pp. 21-28
At GANIL we have developed a beam profile monitor based on ionization
of the residual gas of the beam transport lines under the impact of hi
gh energy heavy ion beams. The charged ions of the residual gas drift
by means of an electrostatic field onto a microchannel plate (MCP), wh
ich yields signals collected on a multistrip anode, providing the spat
ial distribution of the beam. Calculations and results are presented a
s well as discussions about the different parameters of the device.
