FT-ICR is a powerful non-destructive detection method,
for detecting electrically charged particles in an Ion Trap. We provide know-how in
construction, and operation of FT-ICR-Cells, roomtemperature and cryogenic, with focus on ultra high-resolution Traps and
detection of few to single particles. Versatile low noise FT-ICR amplifiers are available on stock (300K...4.2K).

Our part in this project (2002..2004) was particularly consulting service concerning the
construction of the trap and its optimization with regard to the high-resolution non-destructive detection
of single heavy ions per FT-ICR with single charge sensitivity.

The following example shows a FT-ICR-Resonance of a single carbon ion, having a line width of about 0,02Hz, corresponding to a resolution of 1ppb (= 10-9). Measurement time: less than 2 minutes. |

In collaboration with the KATRIN-group, we are currently developing a set of FT-ICR Ion Traps, which can be used for the online analysis of the ion composition in the beam line right inside the experiment. These informations are useful to estimate systematic effects concerning the analysis of the β-spectrum. |
