Electronic Ion Detection

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.
Some examples
Nondestructive electron axial detection for Penning traps   FT-ICR-Resonance of a single carbon ion, quintuple charged

FD 1-40 Frequency Downconverter
Picture: FD 1-40 Frequency Downconverter
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
