Description

Contaminants reduction in Electron Cyclotron
Resonance Charge Breeders (ECRCB) is a key point
for the future experiments foreseen at LNL and
GANIL Isotope Separation On Line (ISOL) facilities.
According to the mass separator resolution set
downstream the ECRCB, the radioactive ion beam
study can be challenged in case of low production
rate. An ongoing collaboration between LNL, LSPC
and GANIL laboratories aims to improve the beam
purity, acting on all the pollutant causes.
Comparative experiments will be done at LPSC using
different techniques, like covering the plasma
chamber wall with liners in several material. Different
configurations of the ECRCB will also be tested, with
the enhancement of the efficiency and charge
breeding time parameters as additional objectives. A
presentation of this program is proposed together
with the effective upgrade of the LPSC 1+N+ test
bench which goal was to improve the vacuum quality
and clean all the beam line devices.
