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).

high-resolution FT-ICR-Trap at GSI GmbH, Darmstadt.
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. |
