Degradation of Polymers
Degradation due to Monochromatic Aluminum X-rays and an Electron Flood Gun
This series of overlaid spectra are from a time based study of Polymers that shows how they degrade due to the total cumulative flux of Al X-rays during an overnight run (~14 hr).
The bright BLUE colored line is the Initial measurement, where degradation is limited to a few minutes of time due to the initial measurement itself.
