The AMS facility DREAMS (DREsden Accelerator Mass Spectrometry facility) has been installed in 2011. The system is based on a 6 MV tandetron manufactured by High Voltage Engineering Europa (HVE). This accelerator also includes several other beamlines used independently by other groups within the Institute of Ion Beam Physics and Materials Research at HZDR.
The DREAMS facility includes two different ion sources. One of them is a modified version of the HVE ion source SO-110A, developed by the group and specifically designed to reduce cross-contamination between samples. This ion source is mainly used for radiohalide AMS (36Cl and 129I).
For 10Be and 36Cl measurements, the degrader method is used, where a silicon nitride foil is inserted between the analyzing magnet and the 35° electrostatic analyzer, thereby providing effective suppression of 10B and 36S, respectively.
The DREAMS facility is currently used for routine AMS measurements of 7Be, 10Be, 26Al, 36Cl, 41Ca, 55Fe and 129I.
