A universal and competitive compact AMS facility

The 600 kV AMS facility at ETH/PSI has been upgraded to a universal platform for AMS at low energies allowing to perform studies of 10Be, 14C, 26Al, 41Ca, 129I, 236U and Pu. The most significant improvement in performance is due to a new gas ionisation chamber of much better energy resolution. Performance for 10Be, 14C, 26Al, 129I and Pu isotopes is now competitive with larger AMS facilities. The background in 41Ca measurements is sufficiently low to measure samples for biomedical applications.
