UNILAC Status and Developments

During the beam time in 2003 a carbon beam from the ECR ion source was mainly accelerated via the high charge state injector (HLI) in the UNILAC for the SIS-injection like in the years before [1]. Several UNILAC experiments used the beam with high duty factor additionally. Additionally, the ECR source was in operation for the production of various isotopes (2H, He, Ne, Mg, Ar, Ca, Cr, Zn, Xe). Mainly experiments for the super heavy element synthesis (SHIP) and the nuclear chemistry requested beam time for the experimental hall. Additionally, ion beams from the ECR were injected into the SIS (Rising collaboration, ESR-experiments). The Penning ion source provided carbon, calcium, argon, titanium, vanadium, ferric, krypton and molybdenum beams with medium intensity, especially when the ECR was in use for the irradiation of patients. For heavy ions (Au, Bi, U) a beam from the PIG source was accelerated via HSI in the UNILAC with short pulses mostly for the injection into the SIS 18. Additionally U was used for HSI-RFQ-Tests. The MUCIS provided a high current beam for the re-commissioning of the HSI after shutdown 2 (Ar) and for different high energy experiments with high intensities (N2, Kr, Kr). The MEVVA ion source delivered only once a high intensity tantalum beam, accelerated via HSI in the UNILAC for SIS injection. Due to serious problems with the delivery of uranium cathodes no high current uranium beam operation was performed in 2004. Besides only 97 hours (209 hours in 2003) for accelerator tests were available, resulting in a reduced program for machine development.
