The classical PHOENIX 28 GHz electron cyclotron resonance ion Source (ECRIS) has been developed to prospect high pulsed multi charged lead ion (MCI lead) beams for the Large Hadron Collider (LHC) [1,2]. The goal of the experiment is to reach 1 emA pulses of Pb27+ during 0.4 ms with a 10 Hz repetition rate. This high beam current is one order of magnitude higher than the ones available nowadays. The strategy to take up this challenge is based on an increase of the radio frequency (RF) to 28 GHz and an increase of the RF power density. A new high acceptance, high resolution analysing beam line has been coupled to PHOENIX in order to study efficiently the intense beams delivered by the source. Thus, 0.6 emA of Xe20+ has been measured in the afterglow (AFG) among 9 emA analysed in the Faraday Cup (FC). The lead production is under study and a preliminary beam of 0.6 emA of Pb24+ AFG has already been obtained. The cross check of a 3D beam simulation program and measured beam characteristics enables to estimate the beam emittance to be ~ 200 mm.mrad. The project of development of an upgraded version of PHOENIX is presented (a new ECRIS named APHOENIX).
