The EXCYT radioactive beam facility at LNS, based on the ISOL (Isotope
Separator On Line) technique, will start producing its first radioactive
beams during 2004. We are setting up a suitable high sensitivity
diagnostics, in order to guarantee a real time monitoring of the beam
parameters (transversal profiles, ion composition and current), offering
also the capability to perform the beam imaging at very low beam energy
(50 keV). For this purpose, a simple technique based on the use of a thin
CsI(Tl) scintillating plate that does not require any amplification
system inside the beam pipe, has been employed. Tests performed with
stable beams have shown a current sensitivity well below 105 pps, a value
that can be improved by adopting a more suitable lens and an intensified
and cooled CCD camera.
