MICADAS Accelerator Mass Spectrometer

The heart of the BRAMS Facility is a MICADAS MIni CArbon DAting System.  The Bristol MICADAS is equipped with a 200 kV tandem accelerator employing helium stripping, which gives a transmission of almost 50%, a cesium sputter ion source capable of accepting both solid and gas cathodes, and a state of the art gas ionisation detector detector.  It is also one of the first AMS systems in the world to employ permanent 'green' magnet technology.  This results in a much lower power consumption; whilst magnetic field strength and measurement stability remain excellent.
