    "abstract": "The UNILAC was improved for high current performance by replacing the Wideroe\nprestripper accelerator by an RFQ and an IH-type DTL. In addition, one of two\nion source terminals was equipped with high current sources of MUCIS- and\nMEVVA-type. Therefore, a redesign of the LEBT from the ion source to the RFQ\nentrance was necessary. The new LEBT was installed at the beginning of 1999.\nThe commissioning was carried mainly with a high intense argon beam. The\nachieved 17 emA Ar+ are 6 emA above the RFQ design intensity. The expected\nperformance of the new LEBT was achieved: full transmission for high current\nbeams, preservation of brilliance along the beam line, isotope separation for\nall elements, transverse phase space matching to the RFQ linac, and macropulse\nshaping. In particular, the high degree of space charge compensation was\nconfirmed.",
