Great development. If I understand correctly, your current system includes one Faraday cup behind the focal plane that is connected with Zeptona electrometer. What is the prospect of building a system with several such electrometers? Do you expect that the mechanism of cup movement would be the dominant source of noise for such a system? Would it be advantageous to put it in a mass spectrometer with fixed cups and variable dispersion (zoom lens)?

Very fascinating how technology is advancing. Would this be something where gains are seen most specifically in the U-Pb system or would this be widely obtained when other isotope systems are measured?

Shaun, could you comment on the temperature and temperature stability of the Atona/Zeptona detector housing? What is the requirement for getting stable baselines, gains and measurement precision?

Do you have linearity issues when charged up to high voltages due to changes in ghost capacitance and or electrostatic flexure in components?
