New Ionisation Measurement Concept

...was proposed.
Measuring few points of V-A Chart before a spike => no EMC interferences.
HV ~ 100V digitally adjustable
- uC unit will have an extra dig. outputs
- HV PS will have an D/A converter in the feedback for adjustment

Current measurement by a TIA (with integration)

Double shielding will be still necessary but now in opposite way.
Electrodes: 100x100 mm
