Abstract

As a part of future developments of beam diagnostics, a low energy experimental bench (LEEx-B) has been recently designed, built and commissioned at IPHC-CNRS of Strasbourg. The bench is composed of a Cs+ ion gun installed on a HV platform and providing beams up to 25 keV. A beam profiler and an Allison-type emittance-meter allow the qualification of the setup and also the characterization of the beam. During the commissioning process, the electronics, and the control system were upgraded in order to push the limits towards low beam currents measured by the emittance-meter.
