We offer a variety of non-destructive electronic detection
systems for Ion Traps. They allow you to perform a medium-resolution (axial detection)
or a high-resolution (FT-ICR-Detection) analysis of particles. These detection systems can
be provided custom specific or as standard modules, sensitivity up to Single Ion
Detection is feasible.
Using of novel phase sensitive spin detection technique in conjuction
with our custom modules allows measurement on single heavy ions and
protons.

The FD 1-40 is intended for downconverion of ion signals from the
MHz-range (1 to 40MHz) down to the LF (low frequency) range of 0...40kHz. It is a
multichannel device, which has 2 inputs and 8 output channels.
Features:
- Input Frequency Range 0.1 ... 40MHz
- 8 Independent Output Channels
- Individually Selectable L.O. Frequencies for Every Channel
- LabVIEWTM Source Code Available
- Typical Application: Ion FT-ICR Experiments
