Article Synopsis
- A new method has been developed to maintain constant gas pressure in in situ measurements, specifically demonstrated in a high-pressure X-ray photoelectron spectroscopy system.
- By using the pressure of a differential stage as feedback to adjust the sample's position, the technique achieves remarkable consistency within a few hundred nanometers, outperforming typical optical microscopy limits.
- This method effectively compensates for thermal drift and allows continuous data acquisition while heating the sample, maintaining pressure within 5% variation even during significant gas flow changes.
