stahl-electronics.com - Ion Trap Design and FT-ICR

We provide support in the design, construction and operation of Ion Traps, roomtemperatur and cryogenic (4.2K), comprising Paul-, Penning- and FT-ICR-Traps. Our service includes the fundamental planning, time and cost estimation as well as the realization into a real measurement set up.
We provide mechanical and electronical components and support embedding them into existing setups.
Some examples of our latest projects:

Ion Trap for highly charged ⁴⁰Ca¹⁹⁺-Ions

Precision Penning Trap for fundamental research at the University of Mainz, Depart. of Physics

Picture: Precision Basic Research Penning Trap at the University of Mainz, Depart. of Physics. Our part in this project are optimizations and modifications with regard to ions species, and greatly improved and extended cryo electronics (2004...2006). The trap is routinely operated at cryo temperatures (T = 4.2K).

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.

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.
