A modern, low-cost universal controller for hot-cathode ionization vacuum gauges.
Many physics experiments require a good vacuum and therefore tools to diagnose vacuum-related problems. Ionization gauges provide a way to measure pressures in the medium to ultra-high vacuum regimes.
While the gauges themselves can be procured quite easily, the controller situation is more problematic. Existing commercial and DIY solutions have one or more of the following issues:
- poor performance at low (pA) collector currents
- designed with obsolete components and overly bulky
- lack of gauge voltage/current programmability
- no/poor connectivity to a logging database
- poor design and construction
The ionpak features:
- a single-board low-cost design with modern components
- open hardware and software
- sub-pA electrometer performance
- configurable voltages and emission current to adapt to various gauges
- Ethernet connectivity
