Description
The RIMS-setup at the University of Hannover uses multiple grating-tuned Ti:Sa lasers to access a range of resonant ionization schemes. Combined with mass spectrometry, the method can detect actinides in single radioactive particles from the environment, down to 107 atoms of a single isotope [1]. In micron-sized particles from the Chornobyl exclusion zone, the relative 238Pu content can be determined by suppressing the dominant 238U in spent fuel. This is achieved quasi non-destructively without chemical preparation of the sample. The current capabilities of the RIMS-system are presented in this poster, with an outlook on further developments of the method and application to ultra-trace analysis.
